Cataract: Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)Cataract Extraction: The removal of a cataractous CRYSTALLINE LENS from the eye.Lens, Crystalline: A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.Lens Nucleus, Crystalline: The core of the crystalline lens, surrounded by the cortex.Phacoemulsification: A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1)gamma-Crystallins: A subclass of crystallins that found in the lens (LENS, CRYSTALLINE) of VERTEBRATES. Gamma-crystallins are similar in structure to BETA-CRYSTALLINS in that they both form into a Greek key-like structure. They are composed of monomeric subunits.Lens Implantation, Intraocular: Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.Visual Acuity: Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.Lens Cortex, Crystalline: The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.Lens Capsule, Crystalline: The thin noncellular outer covering of the CRYSTALLINE LENS composed mainly of COLLAGEN TYPE IV and GLYCOSAMINOGLYCANS. It is secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears.Crystallins: A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.Lenses, Intraocular: Artificial implanted lenses.Blindness: The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.Aphakia, Postcataract: Absence of the crystalline lens resulting from cataract extraction.Pseudophakia: Presence of an intraocular lens after cataract extraction.beta-Crystallin A Chain: The acidic subunit of beta-crystallins.Ophthalmology: A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.Eye Diseases: Diseases affecting the eye.beta-Crystallin B Chain: The basic subunit of beta-crystallins.Capsulorhexis: The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (Dorland, 28th ed)Lens DiseasesGenes, Dominant: Genes that influence the PHENOTYPE both in the homozygous and the heterozygous state.alpha-Crystallin A Chain: One of the subunits of alpha-crystallins. Unlike ALPHA-CRYSTALLIN B CHAIN the expression of ALPHA-CRYSTALLIN A CHAIN is limited primarily to the lens (LENS, CRYSTALLINE).Vision Disorders: Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).Pedigree: The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.Anterior Chamber: The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (Cline et al., Dictionary of Visual Science, 4th ed, p109)Visually Impaired Persons: Persons with loss of vision such that there is an impact on activities of daily living.Anesthesia, Local: A blocking of nerve conduction to a specific area by an injection of an anesthetic agent.Eye ProteinsGlaucoma: An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)Refractive Errors: Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.Aqueous Humor: The clear, watery fluid which fills the anterior and posterior chambers of the eye. It has a refractive index lower than the crystalline lens, which it surrounds, and is involved in the metabolism of the cornea and the crystalline lens. (Cline et al., Dictionary of Visual Science, 4th ed, p319)IndiaEye Injuries: Damage or trauma inflicted to the eye by external means. The concept includes both surface injuries and intraocular injuries.Microphthalmos: Congenital or developmental anomaly in which the eyeballs are abnormally small.alpha-Crystallins: A subclass of crystallins that provides the majority of refractive power and translucency to the lens (LENS, CRYSTALLINE) in VERTEBRATES. Alpha-crystallins also act as molecular chaperones that bind to denatured proteins, keep them in solution and thereby maintain the translucency of the lens. The proteins exist as large oligomers that are formed from ALPHA-CRYSTALLIN A CHAIN and ALPHA-CRYSTALLIN B CHAIN subunits.Sodium Selenite: The disodium salt of selenious acid. It is used therapeutically to supply the trace element selenium and is prepared by the reaction of SELENIUM DIOXIDE with SODIUM HYDROXIDE.Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.Vitrectomy: Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.Corneal Opacity: Disorder occurring in the central or peripheral area of the cornea. The usual degree of transparency becomes relatively opaque.Postoperative Complications: Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.Astigmatism: Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed)Vitreous Body: The transparent, semigelatinous substance that fills the cavity behind the CRYSTALLINE LENS of the EYE and in front of the RETINA. It is contained in a thin hyaloid membrane and forms about four fifths of the optic globe.Vision, Low: Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).Iris Diseases: Diseases, dysfunctions, or disorders of or located in the iris.Lod Score: The total relative probability, expressed on a logarithmic scale, that a linkage relationship exists among selected loci. Lod is an acronym for "logarithmic odds."Postoperative Period: The period following a surgical operation.Aldehyde Reductase: An enzyme that catalyzes reversibly the oxidation of an aldose to an alditol. It possesses broad specificity for many aldoses. EC 1.1.1.21.Connexins: A group of homologous proteins which form the intermembrane channels of GAP JUNCTIONS. The connexins are the products of an identified gene family which has both highly conserved and highly divergent regions. The variety contributes to the wide range of functional properties of gap junctions.Aphakia: Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.Eyeglasses: A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.Galactosemias: A group of inherited enzyme deficiencies which feature elevations of GALACTOSE in the blood. This condition may be associated with deficiencies of GALACTOKINASE; UDPGLUCOSE-HEXOSE-1-PHOSPHATE URIDYLYLTRANSFERASE; or UDPGLUCOSE 4-EPIMERASE. The classic form is caused by UDPglucose-Hexose-1-Phosphate Uridylyltransferase deficiency, and presents in infancy with FAILURE TO THRIVE; VOMITING; and INTRACRANIAL HYPERTENSION. Affected individuals also may develop MENTAL RETARDATION; JAUNDICE; hepatosplenomegaly; ovarian failure (PRIMARY OVARIAN INSUFFICIENCY); and cataracts. (From Menkes, Textbook of Child Neurology, 5th ed, pp61-3)Vision Tests: A series of tests used to assess various functions of the eyes.DNA Mutational Analysis: Biochemical identification of mutational changes in a nucleotide sequence.Refraction, Ocular: Refraction of LIGHT effected by the media of the EYE.Myopia: A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.Ophthalmic Solutions: Sterile solutions that are intended for instillation into the eye. It does not include solutions for cleaning eyeglasses or CONTACT LENS SOLUTIONS.

Modifications to rat lens major intrinsic protein in selenite-induced cataract. (2/2726)

PURPOSE: To identify modifications to rat lens major intrinsic protein (MIP) isolated from selenite-induced cataract and to determine whether m-calpain (EC 3.4.22.17) is responsible for cleavage of MIP during cataractogenesis. METHODS: Cataracts were induced in rats by a single injection of sodium selenite. Control and cataract lenses were harvested on day 16 and dissected into cortical and nuclear regions. Membranes were washed with urea buffer followed by NaOH. The protein was reduced/alkylated, delipidated, and cleaved with cyanogen bromide (CNBr). Cleavage products were fractionated by high-performance liquid chromatography (HPLC), and peptides were characterized by mass spectrometry and tandem mass spectrometry. MIP cleavage by m-calpain was carried out by incubation with purified enzyme, and peptides released from the membrane were analyzed by Edman sequencing. RESULTS: The intact C terminus, observed in the control nuclear and cataractous cortical membranes, was not observed in the cataractous nuclear membranes. Mass spectrometric analysis revealed heterogeneous cleavage of the C terminus of MIP in control and cataract nuclear regions. The major site of cleavage was between residues 238 and 239, corresponding to the major site of in vitro cleavage by m-calpain. However, sodium dodecyl sulfate-polyacrylamide gel electrophoresis and mass spectrometric analysis indicated that in vivo proteolysis during cataract formation also included sites closer to the C terminus not produced by m-calpain in vitro. Evidence for heterogeneous N-terminal cleavage was also observed at low levels with no differences between control and cataractous lenses. The major site of phosphorylation was determined to be at serine 235. CONCLUSIONS: Specific sites of MIP N- and C-terminal cleavage in selenite-induced cataractous lenses were identified. The heterogeneous cleavage pattern observed suggests that m-calpain is not the sole enzyme involved in MIP C-terminal processing in rat lens nuclei.  (+info)

Anterior polar cataracts in CS rats: a predictor of mature cataract formation. (3/2726)

PURPOSE: The objective of this study was to characterize the morphology of the anterior opacities formed during recovery from posterior subcapsular cataract (PSC) in Royal College of Surgeons (RCS) rats. METHODS: Lenses from RCS rats at 8 and 12 weeks postnatal (n = 14 and 12, respectively) were examined under a dissecting microscope for the presence of anterior opacities. Lenses with anterior opacities were fixed, embedded in epoxy resin, and sectioned along the optic axis for light microscopy (LM) and transmission electron microscopy (TEM). RESULTS: At eight weeks postnatal, 21.5% of animals (3/14) had anterior cataracts. Light microscopy of 1- to 2-microm-thick sections revealed an anomalous layer of material located at the epithelium-fiber interface, which was identified as a zone of liquefaction by TEM. Epithelial cells had minor structural defects but were not necrotic. Anterior portions of elongating and cortical fibers under the zone of liquefaction were undisrupted, whereas their posterior portions had numerous vacuoles. The anterior opacities were classified as anterior polar cataracts (APCs) based on the location and type of morphologic damage in the affected lenses. At twelve weeks postnatal, 25% of animals (3/12) had APCs that involved prominent vesiculation of the anterior cortex. Ultrastructural examination showed that large vesicles were located between and inside anterior fibers and that most extracellular spaces were abnormally widened. Posteriorly, internalization of the PSC by new fiber growth was disordered and displayed vesiculation and density variations. In the bow region, LM revealed minor structural irregularities that were identified as groups of apparently degenerating fibers by TEM. CONCLUSIONS: APCs in RCS rats are caused by degeneration of elongating fibers in the bow region and subsequent damage in the superficial anterior cortex. The percentage of animals with APCs (25%) was consistent with the percentage of animals in which mature cataracts eventually develop. The morphologic changes, time of onset, and percentage of animals affected suggest that APC is the initial manifestation of mature cataract formation in RCS rats.  (+info)

Effect of dietary taurine supplementation on GSH and NAD(P)-redox status, lipid peroxidation, and energy metabolism in diabetic precataractous lens. (4/2726)

PURPOSE: To evaluate changes in glutathione and NAD(P)-redox status, taurine and malondialdehyde (MDA) levels, glucose utilization, and energy metabolism in diabetic precataractous lenses and to assess whether these changes can be prevented with dietary taurine supplementation. METHODS: The experimental groups included control and streptozotocin-diabetic rats with a 3-week duration of diabetes fed unsupplemented or taurine (1% or 5%)-supplemented diets. The levels of glucose, sorbitol, fructose, myo-inositol, oxidized glutathione (GSSG), glycolytic intermediates, malate, alpha-glycerophosphate, and adenine nucleotides were assayed in individual lenses spectrofluorometrically by enzymatic methods, reduced glutathione (GSH) spectrofluorometrically with O-phthaldialdehyde, MDA colorimetrically with N-methyl-2-phenylindole, and taurine by high-performance liquid chromatography. Free cytosolic NAD+/NADH and NADP+/NADPH ratios were calculated from the lactate dehydrogenase and malic enzyme systems. RESULTS: Sorbitol pathway metabolites and MDA were increased, and GSH and taurine levels were reduced in diabetic rats versus controls. The profile of glycolytic intermediates (an increase in glucose 6-phosphate, no change in fructose 6-phosphate and fructose 1,6-diphosphate, an increase in dihydroxyacetone phosphate, a decrease in 3-phosphoglycerate, phosphoenolpyruvate, and pyruvate, and no change in lactate), and a 9.2-fold increase in alpha-glycerophosphate suggest diabetes-induced inhibition of glycolysis. Free cytosolic NAD+/NADH ratios, ATP levels, ATP/ADP, and adenylate charge were reduced, whereas free cytosolic NADP+/NADPH ratios were elevated. Lens taurine levels in diabetic rats were not affected by supplementation with 1% taurine. With 5% taurine supplementation, they were increased approximately 2.2-fold higher than those in untreated diabetics but remained 3.4-fold lower than in controls. Lens GSH levels were similar in diabetic rats fed unsupplemented and 5% taurine-supplemented diets, whereas GSSG and MDA levels and GSSG/GSH ratios were reduced by 5% taurine supplementation. The decrease in free cytosolic NAD+/NADH, ATP/ADP, and adenylate energy charge were ameliorated by 5% taurine supplementation, whereas accumulation of sorbitol pathway intermediates, depletion of myoinositol, inhibition of glycolysis, a decrease in ATP and total adenine nucleotide, and an increase in free cytosolic NADP+/NADPH were not prevented. CONCLUSIONS: Dietary taurine supplementation ameliorates MDA levels, GSSG/GSH, and NAD+/NADH and fails to prevent the osmotically mediated depletion of GSH and taurine and the decrease in glucose utilization and ATP levels in diabetic precataractous lens. Dietary taurine supplementation cannot be regarded as an alternative to aldose reductase inhibition in eliminating antioxidant and metabolic deficits contributing to diabetes-associated cataractogenesis.  (+info)

Cardiac involvement in proximal myotonic myopathy. (5/2726)

Proximal myotonic myopathy (PROMM) is a recently described autosomal dominantly inherited disorder resulting in proximal muscles weakness, myotonia, and cataracts. A few patients with cardiac involvement (sinus bradycardia, supraventricular bigeminy, conduction abnormalities) have been reported. The cases of three relatives with PROMM (weakness of neck flexors and proximal extremity muscles, calf hypertrophy, myotonia, cataracts) are reported: a 54 year old man, his 73 year old mother, and 66 year old aunt. All three presented with conduction abnormalities and one had repeated, life threatening, sustained monomorphic ventricular tachycardia. This illustrates that severe cardiac involvement may occur in PROMM.  (+info)

Changing trends in barriers to cataract surgery in India. (6/2726)

Cataract is a major cause of blindness in Asia. Efforts in India to provide cataract surgical services have had limited success in reaching the cataract-blind population. Earlier studies identified the major barriers to cataract surgery as poverty, lack of transportation or felt need, or sex related; and the critical barriers in rural areas as lack of awareness, difficult access, and cost. Compared with these earlier data, the results of the present study in Karnataka State indicate a shift in the character of the barriers. They now appear to be more related to case selection and service provision. These shifts are analysed and alternative strategies to increase the uptake to cataract surgery are recommended.  (+info)

Deamidation of alpha-A crystallin from nuclei of cataractous and normal human lenses. (7/2726)

PURPOSE: To quantitate the extent of deamidation of asparagine-101, glutamine-50, and glutamine-6 of alpha-A crystallin in the nucleus from human cataractous and normal lenses. METHODS: Reverse phase chromatography was used to prepare alpha-A crystallin from total proteins of the nucleus from cataractous and age-matched normal human lenses. Synthetic peptides were made corresponding to the expected amidated and deamidated tryptic fragments containing asparagine-101, glutamine-50, and glutamine-6. The peptides were used to identify and quantitate amidated and deamidated forms of tryptic fragments from alpha-A crystallin eluting from a reverse phase column. RESULTS: Significant amounts of deamidation of asparagine-101 and glutamine-50, but not glutamine-6, were present in alpha-A crystallin from nuclear sections of both cataractous and age-matched normal lenses. Quantitative analysis of tryptic peptides containing these residues indicated no statistical difference in deamidation in cataractous versus normal lenses. CONCLUSIONS: There was no significant difference in the extent of deamidation of asparagine-101, glutamine-50, and glutamine-6 for alpha-A crystallin, purified from the nucleus of cataractous versus age-matched normal lenses. These results strongly suggest that deamidation of these residues does not play a role in the biogenesis of human nuclear cataract.  (+info)

Management of phacolytic glaucoma: experience of 135 cases. (8/2726)

We retrospectively analyzed 135 eyes with phacolytic glaucoma. A trabeculectomy was added to standard cataract surgery if symptoms endured for more than seven days, or if preoperative control of intraocular pressure (IOP) with maximal medical treatment was inadequate. In the early postoperative period, IOP was significantly lower in the combined surgery group (89 eyes) compared to the cataract surgery group (46 eyes) (p < 0.001). At 6 months there was no difference in IOP or visual acuity between the two groups. There were no serious complications related to trabeculectomy. It is reasonable to conclude that in eyes with a long duration of phacolytic glaucoma, addition of a trabeculectomy to cataract surgery is safe, prevents postoperative rise in intraocular pressure and decreases the need for systemic hypotensive medications. A randomized trial is on to further address this question.  (+info)

Cataracts are a degenerative eye condition usually associated with advanced age, but people of all ages can be treated for cataracts. June is Cataract Awareness Month, so lets explore some of the most common questions about early cataract development and treatment.. What Causes Cataracts. Most people will eventually develop a cataract, but some cataracts form earlier or quicker. Certain environmental factors, health conditions and lifestyle habits can cause cataracts to form more rapidly. These include cigarette smoking, UV exposure, eye trauma, hypertension, diabetes, steroid use, or genetic predisposition to early cataracts.. How Do You Know If You Have Cataracts. Cataract development is a slow and progressive process. In fact, you probably wont know you have a developing cataract until your ophthalmologist tells you. It may be years before the cataract begins to impair your vision and cause symptoms like double vision, blurred vision, muted colors, glares and halos.. When to Have Cataract ...
Posterior subcapsular cataracts were studied in 10 patients (19 eyes) and were photographed at four to 12 weeks intervals by the Oxford Retroillumination Camera. Changes in the fine structure of PSC may occur in as short a time as four weeks. Posterior subcapsular cataracts are shown to be in a state of flux and are not, as might be assumed, slowly but relentlessly progressive. This could imply the existence of a repair mechanism in the lens. ...
definition of PSC, what does PSC mean?, meaning of PSC, Posterior Subcapsular Cataract, PSC stands for Posterior Subcapsular Cataract
Congenital cataract, although uncommon, accounts for about 10% of childhood blindness.1 The cataract is usually seen as an isolated abnormality but may occur in association with other ocular developmental or systemic abnormalities. About 50% of bilateral cases have a genetic basis. Congenital cataract is both clinically and genetically heterogeneous; isolated congenital cataract is usually inherited as an autosomal dominant trait although autosomal recessive and X linked inheritance are seen less commonly.2 Most progress has been made in identifying the genes causing autosomal dominant congenital cataract.2 Two main approaches have been used to identify the causative mutations. In large families linkage analysis has been used to identify the chromosomal locus followed by screening of positional candidate genes; most genes have been identified using this strategy. A second approach has been to screen DNA from large panels of patients with inherited cataract for mutation in the many candidate ...
Cataracts. A cataract is a clouding of the eyes natural lens, which is behind the pupil and the iris.. There are various types of cataracts:. A cortical cataract is diagnosed as a white, wedge-like opacity that starts in the outer corners of the lens and work their way to the center of the lens. Cortical cataracts occur in the lens cortex, which is the part of the lens that surrounds the central nucleus.. People with diabetes or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract. The subcapsular cataract occurs at the back of the lens. Nuclear cataracts form deep in the central area (nucleus) of the lens. Nuclear cataracts are typically associated with aging.. Symptoms. At first, cataracts dont affect your vision greatly. Gradually, you may notice that your vision is blurred slightly. It may become hazy, like looking through a cloudy piece of glass.. A cataract may make you more sensitive to light. Driving at night may become more difficult. ...
Purpose: : Matrix Metalloproteinases (MMPs) have been shown to play a functional role in epithelial to mesenchymal transition (EMT) during TGFß-induced anterior subcapsular cataract (ASC) formation. A new model of ASC using adenoviral gene delivery (AdTGFß1) was employed in MMP-9 knock out (KO) mice to examine the requirement of MMP-9 expression in TGFß-induced cataract formation. Methods: : Wild-type and MMP-9 KO mice, on an FVB background, aged 6-8 weeks were injected with recombinantion-deficient adenovirus containing cDNA coding for active porcine TGFß1 (AdTGFß1) or control vector (AdGFP) containing green fluorescent protein, into the anterior chamber of the eye. The animals were sacrificed at 4 and 21 days post-injection. The eyes were dissected, fixed for histology and stained with Massons Trichrome or used for immunohistochemical localization of α smooth muscle actin (α-SMA). Results: : In the wild-type mice (day 4 (n=7); day 21 (n=2)) post-injection, adenovirally delivered active ...
Figure 1 cataract surgery in patients with age and axial length of the scatter plot 3 Discussion Senile cataract blindness in Chinas current primary eye disease, population growth and aging makes the sharp rise in the number of cataract is still the best way to resolve through the surgery to see again [1-3]. Epidemiological research suggests that a large number of senile cataract formation more risk factors: smoking, alcohol consumption, ultraviolet radiation, such as diabetes and corticosteroids [4], but the exact cause of the disease is not clear. Cataract and refractive error correlation between the reports [5,6] is greater: cortical cataract may appear astigmatism change; nuclear cataract can cause progression of myopia; a high degree of myopia and cataract formation are relevant, medium and low degree of myopia associated with cataract formation is still in dispute. Myopia may be the mechanism leading to cataract [7,8] is: the regulatory power of myopia declined, making ciliary muscle ...
Purpose: : Preliminary investigations in our laboratory have shown altered morphology and arrangement of lens fiber ends in juvenile (4-6 weeks old) Royal College of Surgeons (RCS) rats during the formation of posterior subcapsular cataracts (PSCs). The changes included the rapid generation of multiple suture sub-branches and fiber end disorganization with an associated redistribution of F-actin in the basal membrane complex (BMC). The present study was undertaken to elucidate the earliest changes that initiate aberrant fiber end migration and to pinpoint their temporal sequence. Methods: : RCS rats (n=23) at ages 2, 2.5, 3, 3.5, 4, 5 and 6 weeks old were euthanized and lenses were enucleated. Fixed lenses from animals at 2-3.5 weeks old were processed either for scanning electron microscopy (SEM) to evaluate morphology, or immunofluorescent confocal microscopy (LSCM) to localize specific molecular components. Lenses from animals at 4-6 weeks old were analyzed by LSCM and correlated with ...
Definition of posterior polar cataract in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is posterior polar cataract? Meaning of posterior polar cataract as a legal term. What does posterior polar cataract mean in law?
A cataract is a clouding of the lens of the eye. As you age, proteins in your lens begin to break down and the lens becomes cloudy. You may not even realize you have a cataract because it usually grows very slowly and may not impede vision early on. While cataracts are rarely dangerous, after many years they will likely affect vision. By age 65, over 90% of people have a cataract and half of the people between the ages of 75 and 85 have lost some vision due to a cataract.. There are several types of cataracts. Each type of cataract develops in a specific portion of the lens. A cortical cataract forms in the shell layer of the lens, known as the cortex, and gradually extends its "spokes" from the outside of the lens to the center. These spokes block or distort the light passing through the eye. This causes glares to form around lights and a loss of contrast between colors and shades. Both near and distance vision are slowly reduced. If left untreated, cortical cataracts can result in vision ...
What is a Cataract?A cataract is a clouding or opacity in the lens of the eye. Depending upon the size of the cataract, it can diminish normal vision. The clouding process is a result of changes in the proteins and lens fibers in the eye. What are the Symptoms of Cataracts?. Cataracts usually form rather slowly, so the symptoms my slowly progress over time. Blurred or hazy vision. Reduced color vision. Increased difficulty seeing at night. Change in prescription. Increased complaints of glare when driving at night. How Common are Cataracts?. Cataracts are very common as you age and cataract surgery is the most commonly performed surgical procedure performed in the world!. What Causes Cataracts?. Most cataracts form as a result of age and time. Other possible causes of cataracts include diabetes, certain medications, UV radiation, smoking, alcohol and nutritional deficiency. Some infants or young children can develop cataracts, but this is very rare. The cause is usually genetics or infection ...
Posterior subcapsular cataract. This patient is a diabetic male whose vision decreased dramatically over the course of about a month. Glare was a significant complaint.
Results:. Three and one half years after single-dose TBI, 51 of the 74 patients (69%) were alive and cataracts had developed in all of these 51 patients. Cataracts developed in 18 of the 90 (20%) patients treated with fractionated TBI, with an 83% (95% CI, 63% to 100%) risk for lens opacification at 6 years\f. Cataracts developed in only 1 of the 33 (3%) patients treated with chemotherapy alone. Incidence of cataracts is higher and lens opacification occurs earlier after single-dose TBI than after fractionated TBI (P , 0.01). With Cox regression analysis, the use of irradiation (relative risk, 21.0), the mode of irradiation (relative risk, 7.4), and the use of steroid treatment (relative risk, 2.9) for more than 3 months after bone marrow transplantation increased the risk for cataract formation. In contrast, age, sex, and chronic graft-versus-host disease did not influence the rate of cataract development. The probability of requiring cataract surgery after 6 years was 85% (CI, 75% to 95%) for ...
In the current study, we confirmed a missense mutation c. 139 G , A in Cx50 (GJA8) in a six-generation Chinese pedigree with congenital cataract. This mutation resulted in an asparagine substitution for aspartic at amino acid residue 47 (D47N).. Cataracts are defined as opacification of the normally transparent crystalline lens, and are the leading cause of vision loss in the world. Congenital cataract is a type of cataract that emerges at birth or during early childhood [5, 18]. The abnormality of lens can interfere with normal development of eyes [5, 19]. Congenital cataracts can be inherited or familial, either as an isolated lens phenotype or as part of a genetic/metabolic disorder, commonly with full penetrance and autosomal dominant transmission [19]. Genetic factors play an important role in congenital cataract [20]. Gene mutations that affecting the lens development during embryonic period are considered to be the main cause [18]. Up to now, more than 39 genes and loci have been ...

Dr. Chaisson explains that just about everyone is at risk for cataracts. If we all live long enough, we will likely develop cataracts because it is a natural part of the aging progress. There are several different things that can attribute to cataract development; aging is the number one cause, but secondary to age is exposure to ultraviolet light, certain medications, diseases and genetics.. Ultraviolet light from the sun will affect the progression or speed of development of cataracts. This is why wearing sunglasses daily is so important; even on an overcast day ultraviolet light will still filter through an overcast sky.. Certain medications such as steroids and anti-psychotics can also contribute to the progression of different kinds of cataracts.. Diabetes can cause a person to develop what is known as a snowflake cataract which are basically a cataract that looks like a snowflake.. Congenital cataracts are a form of cataract that people can be born with. Often this type of cataract is not ...
Cataracts are opacities of the lens of the eye that reduce the amount of light that reaches the retina. For the individual with cataracts, this results in a dimming of vision that can progress to blindness if the cataracts are not treated. In fact, there are currently 15,000,000 people worldwide who have lost their vision due to cataracts. While there is currently no way to prevent the development of cataracts, they can be effectively treated with a cataract surgery procedure. Cataracts can occur as a result of several different causes, but are generally associated with aging. The following are risk factors that can increase the likelihood of developing cataracts: smoking, alcohol use, exposure to sunlight, obesity, diabetes, and use of steroid medications such as prednisone. When cataracts are due to aging they typically occur in both eyes but often affect one eye more than the other.. ...

Introduction. According to recent studies, age-related cataract is responsible for 48 per cent of blindness worldwide, representing around 18 million people. Although cataracts can be surgically removed, in many countries surgical services are inadequate, and cataract remains the leading cause of visual impairment. As people live longer, the number of people with cataract is growing. Cataract is also an important cause of low vision in both developed and developing countries. Even where surgical services are available, low vision associated with cataract may still be prevalent as a result of the long period spent waiting for operations and barriers to surgical uptake, such as cost, lack of information, and transportation problems 1.. The most important causes of adult visual impairment in Brazil include cataract, glaucoma, retinal diseases and non-corrected refractive errors. Cataract accounts for between 40 and 50 per cent of the cases despite the many efforts that have been made over the past ...

There are three main types of cataracts which are categorized by where they are located within the lens. A subcapsular cataract is found at the rear of the lens. Subcapsular cataracts are an increased risk for individuals with diabetes, extreme cases of farsightedness or retinitis pigmentosa or are taking large amounts of steroid medications.A nuclear cataract is a cataract found at the central zone (nucleus) of the lens and is generally associated with aging. Finally, a cortical cataract typically occurs in the lens cortex, the part surrounding the nucleus. Cortical cataracts often start off with cloudy blotches that start in the periphery of the lens and gradually spread toward the nucleus.. ...
Some clinical and epidemiological studies have suggested that Alzheimers Disease (AD) and cataract, may share common pathogenetic mechanisms, subsequently a positive association between the prevalence of AD and cataract, although other studies found no significant relationship between dementia and visual impairment including cataract in the elderly. Little is known about the association between Activity of Daily Living (ADL) and the combination of AD and cataract. To examine the association between ADL and the combination of AD and cataract, we performed a national survey in nursing care institutions in Japan, examining the decreased ADL in elderly with and without AD and cataract for 453 elderly aged 85.0 ± 8.13 years. The proportion, 43.5% of AD in subjects without cataract was significantly higher than that, 23.5% with cataract. Almost all ADL in AD with cataract was significantly lower than that without cataract, although all ADL in cataract patients receiving surgery in AD was significantly (all
Are you suffering from cataract in one or both eyes? Is the cloudiness of the eyes natural lens is robbing you of your vision and quality of life? You no longer need to live with the vision impairment due to cataracts, thanks to cataract surgery.. Anyone thinking about undergoing Cataract surgery should first understand what is cataract.. The simplest definition for cataract is that it is a clouding of the natural lens, also called crystalline lens, in the eye that affects your daily activities and your ability to drive or read, and eventually leads to vision loss.. The only permanent way to repair a cataract is to have a cataract surgery. People with blurred or misty vision decide to have cataract surgery when the cloudiness in the eyes natural lens gets bad enough where the vision cannot be improved with glasses or contact lens.. The surgical removal of cataract is also recommended to prevent other progressive eye disease s, such as diabetic retinopathy- a leading cause of blindness; and ...
Quality of Life after Cataract Surgery. When we think of the impact that cataracts have on people, it is pretty easy to identify that vision decline or loss comes mainly from the blurry cloudy vision that cataracts cause, but also the night vision problems from the glare and haloes associated with cataracts. What is much more important than the vision loss itself is the negative impact on patients quality of life. Recent research published in Acta Ophthalmologica studied the effect of patient quality before and after having cataract surgery. The researchers compared patients with no known cataracts of the same age, health and lifestyle to those who had cataracts before and after cataract surgery. When compared with the general population, cataract patients had much lower health-related quality of life (HRQoL) than those without cataracts as measured by five dimensions: seeing, moving, hearing, performing their usual activities and general discomfort and symptoms. Then at 12 months after ...
Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. In addition to these age related changes, infants may be born with congenital cataracts. Direct ocular trauma and some medications, specifically the long term use of steroids, may also result in cataract formation. Long term exposure to infrared light and microwave radiation may also lead to cataract formation. Many peoples first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels. During cataract surgery, a patients cloudy natural cataract lens is removed and replaced with a synthetic lens to restore the lenss transparency. Following surgical removal of the natural lens, an artificial intraocular lens ...
Patients having cataract surgery at The Eye Clinic of Texas dont have to be concerned with undue restrictions on leaving Houston and flying and air travel after their cataract operation. "Having cataract surgery doesnt need t present a major barrier to air travel of flying," stated Bernard Milstein, M.D. "My cataract patients-especially as they seem to be getting younger-are continuing very active lifestyles. Often they need to get on an airplane or take advantage of air travel arrangements after cataract surgery and dont want to be hindered.". Most cataract surgeons require their patients to be examined the first day after cataract surgery and again at about 5-8 days after a cataract operation. This is the period of time where rare, but potentially serious, complications would likely be detected, if they were to occur. Beyond this period of time it is more a matter of making sure that you have access to continued follow up care at your cataract surgeons direction. If you are contemplating a ...
Background: The pathogenesis of cataract is influenced by a number of factors including oxidative stress. Glutathione S-transferase (GST) catalyses the nucleophilic addition of the thiol of GST to electrophilic acceptors. It is important for detoxification of xenobiotics in order to protect tissues from oxidative damage.. Objectives: To examine whether the interaction of polymorphism of GSTM1 gene and occupational sunlight exposure modulate the risk of cataract.. Methods: Blood samples from 95 subjects with cataract and 95 age and sex matched healthy persons were collected. The genotypes of GSTM1 were determined using PCR.. Results: The null genotype of GSTM1 was associated with an increase in cataract risk in the indoor workplace, but this association was not significant in the outdoor subjects.. Conclusion: The active genotype of GSTM1 has lost its protective role in persons who work outdoors. It is suggested that activity of the GSTμ enzyme may be inhibited in the human lens after ...
A cataract is progressive clouding of the natural lens in your eye. Cataracts are a natural part of aging and are one of the most common causes of vision loss in patients over the age of 65. No medication, laser treatment or exercise regimen can make cataracts disappear. The only way to eliminate a cataract is through surgery. There have been many technological advancements in cataract surgery during the last twenty years. Today, not only is cataract surgery one of the most common surgical procedures in the United States, it is also one of the safest. Cataract surgery no longer requires a hospital stay with bandaged eyes. It is usually performed in an outpatient setting, with patients going home following the procedure. Eye drops are needed for several days to protect against infection and inflammation. Most patients have minimal discomfort and can return to normal activities within 1-2 days after surgery.. During cataract surgery, the cloudy natural lens is removed from the eye and replaced ...
A cataract is when the natural lense of eye becomes foggy, yellowed or cloudy leading to impaired vision. It can also cause significant loss of vision and even blindness, if not treated.. Common symptoms of cataract are blurred vision, glare- sunlight or headlights may appear too bright, poor night vision, colors appear faded, double vision and frequent changes in prescription of your eyeglasses.. Cataracts are considered early-onsets if they happen under the age of 60.. The exact cause of early cataract is not known, however there are some risk factors that can be considered as possible causes:. ...
Dogs can get cataracts in their eyes just like humans can. Cataracts in dogs affect a structure in the eye called a lens. The lens is the globoid structure in the eye filled with a clear jelly-like substance. The lens is very important for sight, as it focuses light onto the retina to create an image that is in turn recognised by the brain. In a cataract, the normally clear lens undergoes changes that cause it to become opaque. The more opaque the lens becomes, the less it is able to fulfil its role in sight.. In most cases, we cannot identify the cause for cataracts in older dogs, and it is thought that genetics play a role. Some breeds, such as Bichon Frise, have a genetic predisposition to developing cataracts at a younger age. Identifiable causes include glaucoma secondary to diabetes, drug reactions or trauma.. A cataract develops over several months to years, and causes a foggy appearance in the eye. Small cataracts may have minimal effects on vision, however large, mature cataracts ...
Well help you understand your condition.. A cataract is clouding that forms on the lens of the eye, causing foggy or hazy vision and sensitivity to glare. Usually cataracts form with age, but they can also be caused by trauma, disease, family history and secondary medical conditions, such as diabetes. Sometimes a medication like steroids can cause a cataract, as can radiation treatments and long-term, unprotected exposure to sunlight. Sometimes a previous eye surgery can lead to a cataract.. Its important to know cataracts cannot spread from one eye to the other and they are not the cause of irreversible blindness. In fact, in most cases once your cataract is removed - and especially if an intraocular lens is implanted in its place - your vision will improve.. The majority of cataracts are discovered during routine eye examinations. If it is determined you have a cataract, you will meet with a surgeon who will further examine your eyes. Sometimes, the cataract may be causing problems even if ...
So You Have a Cataract…What Now?. Over fifty percent of people over the age of 60 (and quite a few younger than that) suffer from cataracts. Almost everyone develops cataracts as they grow older. Cataract formations occur at different rates and can affect one or both eyes.. A cataract is a progressive clouding of the eyes natural lens. It interferes with light passing through the eye to the retina. Aging and other factors cause proteins in the eyes lens to clump together forming cloudy areas. Early changes may not disturb vision, but over time cataracts typically result in blurred or fuzzy vision and sensitivity to light. People with progressed cataracts often say they feel as if they are looking through a waterfall or a piece of wax paper.. During cataract surgery, your cloudy lens (the cataract) is removed and replaced by a clear lens implant (IOL). If surgery is recommended for you, there is GREAT NEWS! Thanks to modern technology, you now have the opportunity to choose a replacement lens ...

A cataract is a clouding of the crystalline lens of the eye, which may occur slowly or rapidly. Symptoms that occur with cataracts include decreased near or distance vision and glare or halos.. Todays cataract surgery utilizes a small incision, no-suture technique. No shots or needles are used behind the eye. The cataract lens is removed with an instrument that uses high energy ultrasound. It is called phacoemulsification. This instrument breaks the cataract up into very small particles, which are then aspirated from the eye.. Following the removal of the cataract, an intraocular lens is placed in the eye through the small incision to take the place of the cataract lens.. Antibiotic drops and steroid or nonsteroidal drops are used in the eye postoperatively. You will be seen on postoperative day one to evaluate the eye. As with any surgery, complications can occur, and there is a possibility of hemorrhage or infection.. After cataract surgery the cataract does not return. However, one out of ...

Until recently, cataracts have typically been associated with older individuals - and for good reason: its one of the most common age-related eye diseases, currently affecting nearly 22 million Americans. Cataracts are so common, in fact, that its estimated by the age of 80, almost half of Americans will have a cataract or go through cataract surgery.. However, theres a new and alarming health trend on the horizon - a significant number of younger people are being diagnosed with cataracts.. Cataracts occur when theres a significant build-up of protein, which forms a cloud over the eye lens. This cloud can make it difficult for people to see, as it prevents light from entering the lens. Cataracts can typically be treated by changing the prescription of a persons eye glasses or, in more severe cases, replacing the damaged eye lens with an artificial one.. Cloudiness usually builds up over time, which is why cataracts are generally aged-related; however, more young people than ever are being ...
Although cataracts are the leading cause of vision loss worldwide, they are treatable with surgery. Cataract surgery is one of the safest and most common procedures performed in the United States today and boasts over a 95 percent success rate. Currently, 9 out of 10 patients regain vision between 20/20 and 20/40, so you can expect positive results when you schedule cataract removal.. The likelihood of developing a cataract as you age is quite high, but it is possible to avoid cataracts or delay their formation. If you do not yet have a developing cataract, there are a few steps that you can take to prevent cataracts:. Wear sunglasses - Exposure to UV rays from the sun can speed cataract formation, so wear sunglasses, even on cloudy days.. Apply sunscreen - Shield the delicate skin around your eyes from sun damage.. Dont smoke - Cigarette smoke contains thousands of toxins that cause cellular damage.. Maintain a healthy weight - Studies show that obesity increases the risk for cataracts, so ...
While it is advised that you get a check up every year, its still important to monitor your health from day to day to see if you notice any changes or develop odd symptoms. Cataracts occur when there is a build-up of protein in the eyes lens. This results in loss of vision due to the clouding of the lens, making it difficult to see. This clouding prevents the passage of light through the eye and can build up over time, even as new cells form. There are four main types of cataracts including age-related cataracts, congenital cataracts, secondary cataracts and traumatic cataracts. Age-related cataracts simply occur as you age, and may happen to anyone. Congenital cataracts are cataracts that infants may be born with due to complications in development, either in the womb or in early childhood. Secondary cataracts develop as a side-effect of other medical conditions such as diabetes, use of certain drugs, or radiation. And lastly, traumatic cataracts can occur after injury has been sustained in ...
... A cataract is a clouding of the eyes natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eyes focus, letting us see things clearly both up close and far away.. The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and allows light to pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.. Most cataracts occur gradually as we age and dont become bothersome until after age 55. However, cataracts can also be present at birth (congenital cataracts) or occur at any age as the result of an injury to the eye (traumatic cataracts). Cataracts can also be caused by diseases such as diabetes or can occur as the result of long-term use of certain ...
The precise pathogenic mechanisms and risk factors of cataract incidence in AD is yet unclear. Corticosteroid therapy is a known risk factor for cataract development, but in AD patients series it has not been demonstrated to be the only cause. We present three patients that had inflammatory skin disorders and developed bilateral cataracts; although not all of them had undergone chronic treatment with corticosteroids. Intumescent cataracts have not been described to be associated with AD; however two of our patients presented them. A possible explanation is that posterior subcapsular cataracts might present a pore and consequent hydration of the nucleus ...
TY - JOUR. T1 - Cytotoxicity to lens epithelial cells of sera from two patients with atopic cataract. AU - Ayaki, M.. AU - Singh, D. P.. AU - Shinohara, T.. AU - Majima, Y.. AU - Majima, K.. AU - Kousaka, M.. AU - Azuma, N.. PY - 1998/1/1. Y1 - 1998/1/1. N2 - We studied the cytotoxic effect of sera from two patients with bilateral atopic cataract. They were aged 19 and 26 years each. The sera was diluted 20 times, mixed with lens epithelial cells of mouse, and was stained by trypan blue after incubation for 3 hours. The incidence of cell death was 22% and 36% respectively. It was 7% in a 33-year-old normal person. The major cytotoxic factors were larger than 100kDa and were neutralized when mixed with the homogenate of lens epithelial cells. Both cases showed high levels of serum histamine. The findings seemed to suggest that atopic cataract was the result of breakdown of blood-aqueous barrier due to serum histamine or repeated rubbing of the eyeball which allowed entrance of autoantibodies to ...
The unexpected benefits of treating cataracts. By BlackDoctor.org. For some, its the fear of the unknown. The survey found that nearly four in 10 African Americans agreed that they were worried something would go wrong and theyd lose their vision or they would end up with visual disturbances after cataract surgery. Ive seen, in my practice and my own family, how this fear can cause people to wait until theyve nearly lost sight before doing something about cataracts. Theres never a reason to live with cataracts. Whats encouraging is that nearly all those surveyed would recommend cataract surgery to people scared of the procedure.. Since June is Cataract Awareness month, its a great time to share advice that might help you overcome fears and bring your life back into focus:. Get the Facts on Cataracts. The fact is that cataracts are a natural part of aging and cant be prevented. They cloud the eyes naturally clear lens, blocking or changing how light passes through and resulting in blurry ...
A cataract is a clouding that occurs in the lens of the eye. Normally, the lens of the eye in the form of a clear and transparent structure. In patients with cataracts, blurred vision clouded the cause of the lens as the next..  blurred or hazy vision..  Sensitive to light. Sometimes when he saw the lights like a halo (halo)..  If you see with one eye, objects can be seen twice..  When seen, the color of an object are like the patients of cataract or yellowish brownish.Eventually view, it would be difficult to distinguish between blue and violet..  vision problems can deteriorate gradually, which can often change the lenses.. So far, no one knows exactly why cataracts form. Aging is a risk factor. Cataract due to aging is called senile cataract.. occur not only in the elderly, although rarely, cataracts occur in children or newborns. The causes are congenital infection, hereditary enzyme abnormalities and other genetic diseases. In addition, the cataract can be triggered by trauma ...
What are the ten types of cataract and what risks are involved? Nuclear cataract, Cortical cataract, Posterior subcapsular cataract, Diabetic cataract,
What Are The Symptoms of Cataracts?. - Nearsightedness, unable to see things that are far away clearly. - Blurry, foggy, filmy or cloudy vision. - Changes in the way color is perceived. - Difficulty driving at night. - Sensitivity to glare from sunlight, preference for dim rooms. - Spectacles or other vision correcting tools not working as well as they did. - Double vision. What Causes Cataracts? In general, the buildup of protein in the eyes causes a non-transparent layer to build up, blocking light from entering the lenses. Usually, the body is able to get rid of these proteins naturally and keep the lens clear, but in the case of cataract patients, this system either malfunctions or slows down significantly.. Multiple Types of Cataracts There are many types of cataracts. The first type affects the elderly and happens as people age. The second type is called congenital cataracts and happens in newborn infants. The third type is secondary cataracts and it happens to those suffering from medical ...
Cataracts can be treated through surgery or eye drops, depending upon the cause of the cataracts, the stage of development and dependent upon the condition of the dog. Eye drops are the newest method of treatment for cataracts and are seeing a lot of success in the canine patients. The drops are an N-acetyl-carnosine solution that gradually lessens the opacity of the crystallized lens. They can be used on most dogs, no matter the age or health condition. The drops can be used in the early stages of a cataract, dissolving the developing crystallization and slowing or reversing the loss of vision. Surgical removal of the cataracts must be completed on a mature cataract and the dog must be relatively healthy to undergo surgery. The crystallized lens is emulsified and removed and often a lens implant is inserted to allow for near vision. Canine cataracts are a condition, that left untreated, can make a significant impact on your dogs activity level and ability to get around. By seeking early ...
A cataract is a cloudy lens inside the eye and is located just behind the iris (color of the eye). The most common sign is a white or gray pupil. However, some cataracts are difficult to see without a complete eye exam.. Pediatric cataracts can be present at birth or develop later in childhood. They could be present in both eyes or only one eye. They can be inherited if there is a family history of childhood cataracts or can occur spontaneously. Some cataracts are caused by metabolic or genetic disorders and additional testing is required to identify problems elsewhere in the body.. As in adults, cataracts in children can limit vision. More importantly, cataracts in a child can lead to amblyopia, strabismus, and nystagmus (uncontrolled, rapid jerking movements of the eyes). While it is possible for a cataract to be so small that it does not affect vision, many childhood cataracts should be removed in a timely fashion to help prevent permanent vision loss.. ...
Background: Cataract is defined as the loss of lens transparency because of opacification of the lens. Age-related cataract is the most prevalent type in adults, with the onset between age 45 to 50 years, while in children hereditary and metabolic causes are most common. Aim of the work: In this study, our aim was to discuss the epidemiology, pathophysiology, classification, risk factors, symptoms, and management of cataracts. Methodology: Weconducted this review using a comprehensive search of MEDLINE, PubMed and EMBASE from January 1981 to March 2017. The following search terms were used: cataracts, causes of cataract, pathophysiology of cataract, management of cataract. Conclusion: Cataract is one of the most common causes of blindness worldwide, and more prevalent in developing countries. It is also the most curable cause of blindness which involves a simple surgical procedure.
The Cataract Lake Trail (# 475) is a direct path to Cataract Lake. The trail begins at the Cataract Gulch Trailhead, which is about 0.5 miles west of the Sherman townsite on County Road 18X. You should expect to wade through Cottonwood Creek to begin this hike. After this creek crossing, the trail climbs into Cataract Gulch. The trails switchbacks climb the gulch quickly. After hiking for about one mile, hikers will now be following the comparatively gentle grade following Cataract Creek.. The Cataract Lake Trail follows and crosses Cataract Creek for the next two miles. During this portion of the hike, the trail ascends moderately to 12,000 feet. The trail enters Cataract Basin, an area of high alpine tundra below the Continental Divide. There are three lakes in this basin with the largest sitting under the highest point on the ridge.. The Cataract Lake Trail is popular with motorcyclist and horseback riders. This area also provides good opportunities for dispersed camping ...
Cataracts occur when the lens inside your eye becomes increasingly opaque resulting in misty or foggy vision.. The cause of cataract is age; however, they can be worsened by steroid use, diabetes and sunlight.. Someone with early stages of cataracts may notice a film in their vision. Often, things that used to be black and white now look grey and colours are perceived as dull. In early stage cataracts, new spectacles may improve vision but as the cataract worsens, spectacles often will not provide significant improvement. You may not be aware of cataracts in your vision because changes can be gradual. As cataracts become more advanced, vision becomes foggy, less detail is seen, reading can be slower, television isnt perfectly clear and driving becomes difficult when driving into the sun. At this stage, new spectacles will not restore normal vision and surgery is required.. Corrective surgery removes the cataract (the cloudy lens) and an artificial lens (intra ocular lens) is put into ...
Dr. Alison Gordon with Gordon Schanzlin New Vision Institute Institute in La Jolla discusses the recovery process from one of the most commonly performed surgical treatments in America. San Diego, CA - It has been estimated that more than half of all Americans will either need to have, or have already had, cataracts removed by the age of 80. Often part of the natural aging process, cataracts are characterized by a formation on the eyes natural lens that leads to cloudy and impaired vision. When left untreated, a cataract can get bigger and bigger, ultimately leading to total vision loss. Dr. Alison Gordon, a San Diego eye surgeon at Gordon Schanzlin New Vision Institute Institute, says advances in cataract surgery have made the removal of cataracts a relatively quick and simple procedure, with a minimal recovery process and results that can give patients much clearer and precise vision.. Cataract surgery typically involves the careful removal of the cataract and, in most cases, the replacement ...
Cataracts in its early development can cause blurred vision, nearsightedness or color blindness. If it goes without treatment and the cataract advances to covering up the lens of the eye, the person can go blind and cannot recover his or her vision unless subjected to cataract surgery. Generally, cataract surgeries are done on outpatient basis, meaning, the person with a cataract can get operated by an eye surgeon and in just few minutes cataract extraction is completed. The patient can rest for a couple of hours in the doctors office and can go home after.. There are things that must be done in order for the operated eye to heal faster and heal successfully. Medicated eye drops, taking antibiotics and regular check-up with the doctor would be necessary. On the other hand, there are people who are asking how soon women can wear eye makeup after cataract surgery. Well the answer to this depends on the condition of the eye after surgery. Generally, the eye needs to be covered with sterile gauze ...

Following the surgery, the follow-up visits can be conducted in the comfort and convienence of the Langner Eye Care office.. Cataract surgery is one of the most common surgeries performed today, and the procedure is much simpler than years ago - in fact, the majority of Dr. Langners patients have vision that is 20/30 or better on day one following surgury (in the operative eye). Advances in cataract surgery and the implanted lenses can now correct for astigmatism and presbyopia - so glasses may not be needed for the majority of tasks (note: not all ...
Cataract removal is one of the most common operations performed in the United States. It also is one of the safest and most effective types of surgery. In about 90 percent of cases, people who have cataract surgery have better vision afterward.. Cataract Surgery/ Laser Cataract Surgery (Phaco/ Femtosecond Laser) are achieved by the removal of the natural lens and the placement of an implant that best fits your personal needs. There are two technologies to choose from when performing this task. There is the most common practice of phacoemulsification wherein the internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye and there is also an advanced bladeless technology wherein a laser is utilized to cut the lens into small pieces prior to being aspirated from the eye. Please ask your surgeon during your consultation which method would be best for you.. More information can be found at www.reclaimyourvision.com/cataract/cataract-surgery-options.shtml.

A cataract is when the naturally clear lens of the eye becomes cloudy. Cataracts usually form slowly over time and may initially only cause a few hazy patches or halo effects around objects. The amount of light that passes through the lens is reduced and scattered distorting the image as it increasingly becomes cloudy. The cataract only affects the lens of the eye and it is not a film or growth over the eye. The majority of people affected by cataracts are over 40 years of age however they can develop in younger patients even as young as babies. According to the Royal Australian and New Zealand College of Ophthalmologists (RANZCO) by the age of 60, there is a 50% chance you will have had some form of cataract and by the age of 70 it increase to more than 90%. Cataract surgery is the most common surgical procedure performed in Australia. It has a very high success rate and may completely restore or even improve on your previous level of vision.. Cataracts can be categorized into 4 main forms: ...
A cataract is a clouding to the natural lens inside the eye. Cataracts develop as part of the natural aging process of the eye. However, cataract development can be caused by or be speed up by previous eye surgery, injury, certain diseases, and even some medications. Cataract development usually does not harm the eye but causes blurry vision. Cataracts usually progress slowly over a period of years and in early stages stronger eye glasses or brighter light may help. As cataracts progress and the lens becomes more cloudy, patients often experience symptoms such as painless blurry vision, glare and haloes around lights at night, double vision in one eye, need for bright light to read, and fading or yellowing of colors.. ...
Cataracts are a leading cause of vision loss in the United States and Canada. Here are 6 things you need to know.. 1. Chances are you will develop a cataract! Cataracts are considered part of the natural aging process so if you live long enough, you will likely eventually develop one. 2. A cataract is a clouding of the usually transparent lens in your eye.. The lens in your eye focuses light onto the retina at the back of your eye, allowing you to see. When your lens starts to clouds up, the images projected onto your retina become blurry and unfocused. You can compare this to looking through a dirty or cloudy window. If the window is not clear, you cant see!. 3. Age is not the only risk factor for cataract development.. While the risk of developing a cataract does increase as you age, it is not the only factor. Other risk factors include eye injury, certain medications (eg: steroids), diseases such as diabetes and macular degeneration, lifestyle choices such as alcohol consumption, smoking and ...

NAC eye drops are prescription medicines that are only available after a consultation with a veterinarian. If your dog appears to have difficulty seeing properly, or if you notice any strange colors or cloudiness in one or both of his eyes, these may be signs of canine cataracts. Take your pet to the veterinarian as soon as you can, as cataracts may develop quickly. If your vet diagnoses your dog with cataracts, speak with him about the proper treatment program for your pet. This depends upon the type and severity of the cataract, your dogs age and overall health condition and your budget. Generally, the two primary methods of treating canine cataracts are surgery and eye drops. Surgical procedures can remove a cataract entirely, but they are expensive, risky and may not be possible for some dogs. Additionally, cataracts that have been surgically removed may redevelop in your pets eyes. NAC eye drops, on the other hand, have been shown to have minimal side effects. They are generally ...

Children who are blind have to overcome a lifetime of emotional, social and economic difficulties which affect the child, the family and society. Loss of vision in children influences their education, employment and social life. Timely recognition and intervention can eliminate blind-years due to childhood cataract, as the condition is treatable
Cataract is the leading cause of treatable blindness in the world. The word "Cataract" originates from the Greek and Latin translations meaning "Waterfall".. This describes the whitish appearance of rapidly running water at the bottom of a waterfall. A cataract is the clouding of the crystalline lens which is located behind the iris. This whitish/yellow clouding occurs as a result of the denaturing of the protein lens fibres that make up the lens.. The most common causes are ageing, exposure to ultra-violet radiation and infra-red radiation, diabetes, certain medications and trauma. The symptoms associated with cataract are blurred or hazy vision, impairment of colour vision and glare.. Cataract can only be treated by surgery. This is by referral to an Ophthalmologist (Eye Surgeon) following an eye examination, who will then remove the lens and replace it with an Artificial Implant to restore the sight. We actively refer most patients in Leicestershire via the Direct Cataract Referral Service on ...

Is your vision blurry, especially at night or in very bright light? It could be an early symptom of cataracts. A cataract is a clouding of the lens of the eye that interferes with clear vision. Unlike a healthy, transparent lens, which focuses light rays precisely onto the retina, a lens clouded by a cataract loses its ability to focus light rays. The light that reaches the retina is scattered and diffuse, causing blurry vision. The amount of vision impairment depends on the size and density of the cataract and where it is located in the lens: the nucleus, cortex, or posterior lens capsule. A cataract in the periphery of the cortex, for example, has little effect on vision because it does not impede the passage of light through the center of the lens. On the other hand, a dense nuclear cataract causes severe blurring, interfering primarily with distant vision (at first). A cataract that develops in the posterior capsule has a greater effect on near vision and also causes sensitivity to glare. ...
Bladeless" laser-assisted cataract surgery as it is commonly promoted is deceptive, as the cataract is not removed by the laser. Instead the cataract must be removed by the same Standard (non-laser) technique called Phacoemulsification.. There is a lot of misleading information being circulated in the media concerning the possible benefits associated with bladeless laser-assisted cataract surgery. It is important in your research that you thoroughly review the financial disclosures of the authors of these articles, publications and websites.. First and foremost, it is important that patients understand that the laser does not remove the cataract. The laser merely assists a surgeon in only several steps of a multi-step operation. Regardless that the femtosecond laser is used, the remaining more technically challenging aspects of the cataract procedure including; removing the cataract from the eye using ultrasound and aspiration, cleaning and polishing the capsular bag, insertion of the ...
Over 20 million Americans aged 40 and older have cataracts, a clouding of the eyes lens and one of the most curable causes of vision loss. Most cataracts are related to aging, but other types of conditions can also lead to cloudy or blurry vision - some of which are very preventable.. The lens of the eye is the clear portion located beneath the pupil and the iris and helps to focus light or an image on the retina, the tissue at the back of the eye. In a normal eye, light passes through the transparent lens to the retina, where nerve signals then send the image to the brain. If the lens is cloudy from a cataract, the image you see will be blurred and colors may seem faded.. Read: Statins May Reduce Risk of Cataracts. Over time, old cells and proteins can clump in the lens which creates the clouding. These age-related cataracts can start small and "grow" slowly. However, a cataract cannot spread from one eye to the other.. ...
Cataracts are the worlds leading cause of blindness and surgery to remove them is the most regularly performed operation in the UK with figures showing that around 300,000 procedures are carried out every year. Yet there are still thousands of people living in the shadows of cataracts.. As part of Cataract Awareness Month, which runs throughout June, eye experts are urging people to know the signs and to seek advice if they think they are developing cataracts.. Mr Amit Patel, a Consultant Ophthalmic Surgeon at Spire Parkway Hospital in Solihull, explained that although cataracts are prevalent, they can be treated successfully to restore vision.. He said: "Cataract Awareness Month gives us a good opportunity to make people aware of the symptoms and impress upon them the need to have their eyes examined.. "A cataract is a clouding of the eyes natural lens, which lies behind the iris and the pupil. Basically the lens focuses light into a sharp image on the retina, which relays messages through ...
The purpose of this study was to valuate the prevalence of nuclear cataract in veal calves and to elucidate a possible impact by mobile phone base stations (MPBS). For this experiment a cohort study was conducted. A follow-up of the geographical location of each dam and its calf from conception through the fetal period up to slaughter was performed. The first trimester of gestation (organogenesis) was particularly emphasized. The activities of selected protective antioxidants (superoxide dismutase, catalase, glutathione peroxidase [GPx]) were assessed in aqueous humor of the eye to evaluate the redox status. Of 253 calves, 79 (32 %) had various degrees of nuclear cataract, but only 9 (3.6 %) calves had severe nuclear cataract. Results demonstrate a relation between the location of veals calves with nuclear cataracts in the first trimester of gestation and the strength of antennas. The number of antennas within 100 to 199 meters was associated with oxidative stress and there was an association ...
A chemical that could potentially be used in eye drops to reverse cataracts, the leading cause of blindness, has been identified by a team of scientists from UC San Francisco (UCSF), the University of Michigan (U-M), and Washington University in St. Louis (WUSTL). The study, published November 5th 2015 in Science, reports that the newly identified compound is the first that is soluble enough to potentially form the basis of a practical eye-drop medication for cataracts.. A release from UCSF explains that cataracts, identified as a "priority eye disease" by the World Health Organization, are caused when the lenses of the eyes lose their transparency. The condition affects affect more than 20 million people worldwide. Although cataracts can be successfully removed with surgery, this approach is expensive. Also, most people blinded by severe cataracts in developing countries go untreated.. Cataracts are primarily a disease of aging. As is seen in neurodegenerative conditions such as Alzheimers ...
Combining cataract and glaucoma surgery in a single procedure is not new. Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service at the Duke Eye Center in Durham, NC has the enormous privilege of working along with one of the top Glaucoma Services in managing patients that have co-existing Glaucoma along with cataracts and corneal problems. A "best practices" approach to patients that simultaneously have visually significant cataracts along with poorly controlled glaucoma is to combine cataract surgery with trabeculectomy. Drs. James Kim and Rand Allingham of the Glaucoma Service at the Duke Eye Center demonstrate meticulous surgical attention to this patient who has both visually significant cataracts and poorly controlled glaucoma. "The Duke Difference" means taking each patient individually and designing a program and procedure that is optimal and specific to their needs.. ...
Cataracts, one of the most common causes of blindness, develop when the lens of the eye, located behind the iris and pupil, becomes opaque or cloudy. A cataract can result in loss of vision as it prevents light from passing into your eye and focusing on the retina.. While cataracts most frequently result from the natural aging process, other risk factors include exposure to UV radiation, medical disease or a family history of the condition, trauma to the eye and smoking.. Cataracts occur when over time, pigment or protein is deposited in the lens and this, together with disruption of the normal structure of the lens fibers, can lead to reduced transmission of light, which causes visual problems. The condition can affect ones ability to see colors, drive, read, and recognize faces. Although cataracts arent painful, the following signs could indicate cataract development:. ...
A cataract is a clouding of the lens of the eye. This is an area that is normally clear. As this clouding happens, it keeps light rays from passing through the lens and focusing on the retina. The retina is a tissue lining that is sensitive to light. It is located in the back of the eye. This cloudiness happens when some of the protein which makes up the lens of the eye begins to change its structure. It then gets in the way of your eyesight. In its early stages, a cataract may not cause a problem. The cloudiness may affect only a small part of the lens. However, the cataract may grow larger over time and affect more of the lens. This can make it harder for you to see. If less light reaches the retina, it becomes even harder to see. Your vision may become dull and blurry. Cataracts cannot spread from one eye to another. Many people do, however, get cataracts in both eyes. There are many types of cataracts:. ...

These.asers have gained approval for the following steps in cataract surgery, reducing the need for surgical blades and other hand-held tools: Creating corneal incisions to allow the surgeon access to the lens Removing the anterior capsule of the lens Fragmenting the cataract so less phaco energy is required to break it up and remove it Creating peripheral corneal incisions to reduce astigmatism when needed Laser cataract surgery or, more accurately, laser-assisted cataract surgery is fairly new and significantly increases cataract surgery cost, primarily because the laser can cost from $300,000 to $500,000 for a surgeon to purchase and there are other significant costs associated with the use and maintenance of this technology. It takes about 2 - 4 weeks for vision to be completely restored. Glaucoma . Your surgeon can advise you about timing of the procedure and possible alternative medications. Cataracts that affect the back of the lens posterior sub capsular cataracts. This procedure can ...
There are some multifocal IOLs that is capable of correcting near vision problems that is commonly caused by presbyopia which in turn can also reduce your need to wear glasses as well. In general, these premium IOLs will let your cataract surgeon recommend you for a laser cataract surgery so that you will achieve the best possible visual outcomes. In some cases, minor refractive errors will still remain even after refractive cataract surgery has been performed. If this happens then LASIK or PRF surgery can be performed several weeks or a few months after to further improve your eyesight even when youre not wearing your sunglasses. You need to know that both laser cataract surgery and refractive cataract surgery will involve some of your own pocket expenses since it can be beyond what your vision or health insurance can cover for the cost of a normal cataract surgery. ...
There is no surgery that does not involve risk. This is also true of eye surgery. Even though cataract surgery techniques now include lasers and high-tech computer mapping, certain complications can still arise during and after surgery. Most minor problems improve on their own but some complications may require additional surgery. Highly experienced surgeons, such as Beverly Hills Vision Institutes Dr. Khodabakahsh, are often sought out for their skill with revision cataract surgery. Dr. Khodabakahsh is expertise is used to treat most lens related eye complications.. Cataract Surgery Basics. A cataract is formed when the natural lens of the eye opacifies to the point of not allowing light to pass through freely to the retina. Similar to a smudge on glasses lenses, cataracts make what you are viewing fuzzy, hazy or cloudy. Cataract surgery aims to remove the protein-riddled lens and replace it with a clear implant, known as an intraocular lens or IOL. The incision in the eye is so small it ...
A. People often think that cataracts can be removed with a laser. This is not true. Cataracts cannot be removed with a laser. In addition, there is no medicine one can take to treat a cataract. Cataracts are treated by microscopic surgery. In cataract micro-surgery, a tiny incision is made in the eye and the cloudy lens is removed through this opening. A clear, plastic lens is then put in the eye to REPLACE the cloudy lens. Following cataract surgery, most people will experience substantial improvement in their vision ...

In this study, we screened 6 genes for mutations in 9 Chinese families with congenital cataract and microcornea. Three mutations were identified in 3 of the 9 (30%) families, including a c.34C,T (p.Arg12Cys) in CRYAA, and a c.136G,A (p.Gly46Arg) and a c.116C,G (p.Thr39Arg) in GJA8, respectively. CRYAA is located in 21q22.3 and encodes the α-A-crystallin in lens epithelial cells and fiber cells. α-A-crystallin is a member of small heat shock proteins with the chaperone activity which contributes to keeping lens transparent [6,10,27]. Up to now, there were eight mutations of CRYAA found in sixteen families most of which involved substitutions from or to arginine [5]. And the corresponding phenotypes of the mutations were related with congenital cataract with or without microcornea, microphthalmia, or iris coloboma. We found a known c.34C,T (p.Arg12Cys) mutation in CRYAA of three patients from a family with congenital nuclear cataract and microcornea. Previously, this mutation has been identified ...

The aging of the baby boomers and the fact that patients older than 65 consume 10 times the eye ...
Cataract is the leading cause of visual impairment worldwide and surgery is the only effective treatment. Previous studies show that visual impairment impacts the patients socioeconomic status(SES). However, how cataract surgery affects the SES of cataract patients in rural area of China has not been determined before.. In the investigators study, cataract patients in rural area of Southern China will be enrolled and randomly divided into two groups. Cataract surgery will be performed in 4 weeks in intervention group, while performed at 1 year later in control group. The annual personal income by work, annual household income, hours in paid and unpaid work in the previous month, real estate ownership, household expenditures and quality of life will be investigated before and 1 year after surgery. Then, the difference in SES and quality of life change between two groups at 1 year later will be assessed. ...
There are many types of cataract. The most common type is age-related. This simply means that all of us will eventually have cataract in varying degrees in our life time. Age related cataract may appear anytime in your later years of life. In some people it may develop early while it may not be visually significant even in their seventies, for instance. Similarly, the degree and type of cataract may vary. The resultant visual disability [...]. ...
While there is no way to prevent cataracts, there are things you can do to slow their formation. Modifiable factors that increase the risk of cataracts include smoking, high blood pressure, obesity, and excessive alcohol intake. You may also slow the formation of cataracts by protecting your eyes from direct sunlight.. In the early stages of cataracts, vision may be slightly improved using forms of visual correction. However, in the later stages of cataract, surgery is required. Fortunately, surgery has proven to be extremely successful in the removal of cataracts. During cataract surgery, your ophthalmologist will replace your natural lens with an intraocular lens (IOL).. ...
Average age of this group is 72 (52-83). Preoperative visual acuity was ranged from hand motion to 2/60. Posterior chamber intraocular lens implantation was made during cataract surgery in 8 eyes. Vitrectomy was preformed immediately after cataract surgery in 6 eyes. Follow-up period was 9,5 (5-19) months. In the group with vitrectomy performed immediately after cataract surgery visual acuity was better than 0,5 in 5 eyes (83%), and less than 0,1 in one eye (17%). In the group with vitrectomy performed after cataract surgery, in the second act, visual acuity was higher than 0,5 in 5 eyes (50%), 0,1-0,5 in 3 eyes (30%) and up to 0,1 in one eye (10%). Secondary glaucoma and uveitis were more often in the case vitrectomy made in the second act and this procedure solve them. Cystoid macular oedema has been noted in one case ...
Cataract surgery is the removal of the natural lens of the eye (also called crystalline lens) that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over the time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. During cataract surgery, a patients cloudy natural lens is removed and replaced with a synthetic lens to restore the lenss transparency.. Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is implanted). Cataract surgery is generally performed by an ophthalmologist (eye surgeon) in an ambulatory (rather than inpatient) setting, in a surgical center or hospital, using local anesthesia (either topical, peribulbar, or retrobulbar), usually causing little or no discomfort to the patient. Well over 90% of operations are successful in restoring useful vision, with a low complication rate. ...
Early Signs of Cataract. Many cataracts are not obvious early on. There are even cases that a person did not know he had such a condition because his vision is still good. However, a cataract should be dealt with immediately by the time you are diagnosed with it. While wearing glasses and adding more lights might help enhance your vision, it will not be long before you will really require surgical treatment. You should consider surgery when you notice the following signs:. Extra Sensitivity to Light. Basically, an advanced cataract would cause your eyes to become highly sensitive to light. If you already have it, you would notice that you will see a halo around brilliant lights.. Double Vision. You will see two images rather of one.. Blurry Vision. This is the very first indication that you are having eye issues. You may need to see out an eye professional to verify whether or not this caused by cataract. Visit at Milan Eye Center. Poor Vision During the Night. When you have a cataract, you will ...
Description: Cataract (cataract) or lens opacity is the best known pathological condition of the lens. Initially, the peripheral parts of the lens are affected, which do not affect the change in vision and sharpness. However, as the cataract progresses toward the center of the lens, vision deteriorates until the individual sees only the difference between light and dark. The transparency of the lens decreases until it finally disappears completely. Such a damaged lens has a grey-white color. Cataracts are a very common hereditary disease and occur in nearly 100 different dog breeds. Various types of inheritance are described in relation to hereditary forms of cataract. Most HC are inherited by autosomal recessive, but they also exist with an autosomal dominant form of inheritance, eventually polygenic inheritance. According to scientific literature, the probability of developing the disease is 17 times higher in a heterozygous Australian Shepherd compared to a clear HSF4 animal. The test cannot ...

Purpose: To screen for mutations of connexin50 (Cx50)/GJA8 in a panel of patients with inherited cataract and to determine the cellular and functional consequences of the identified mutation.. Methods: All patients in the study underwent a full clinical examination and leucocyte DNA was extracted from venous blood. The GJA8 gene was sequenced directly. Connexin function and cellular trafficking were examined by expression in Xenopus oocytes and HeLa cells.. Results: Screening of the GJA8 gene identified a 139 G to A transition that resulted in the replacement of aspartic acid by asparagine (D47N) in the coding region of Cx50. This change co-segregated with cataract among affected members of a family with autosomal dominant nuclear pulverulent cataracts. While pairs of Xenopus oocytes injected with wild type Cx50 RNA formed functional gap junction channels, pairs of oocytes injected with Cx50D47N showed no detectable intercellular conductance. Co-expression of Cx50D47N did not inhibit gap ...

Surgery can remove cataracts. For most adults, surgery is only needed when vision loss caused by a cataract affects their quality of life.. There are a number of things you can do that may help you manage your vision problems. Many people get along very well with the help of eyeglasses, contacts, or other vision aids. Keep your eyeglasses or contact lens prescription up to date. Also make sure you have plenty of lighting in your home. You may be able to avoid or delay surgery.. Whether you need cataract surgery depends on how much of a problem the cataract causes for daily activities like driving and reading. Surgery is almost always by your choice (elective) and can be scheduled when it is convenient. For people who decide to have surgery, the surgery usually works very well.. Some people have to have surgery. Children are sometimes born with cataracts that need to be removed. Other people may get cataracts after an eye injury or as a result of eye disease or other health problems. Cataracts ...
Radiation cataract causes partial opacity or cloudiness in the crystalline lens and results from damaged cells covering the posterior surface of the lens. Symptoms can appear as early as one or two years following high-dose exposure and many years after exposure to lower doses. It is unclear how frequently radiation cataracts advance to severe visual impairment, although we have documented in a recent study about a 20-30% excess at 1 Gy of cataracts that prompted cataract surgery. A low-dose threshold may exist below which radiation cataract does not arise, although our recent analyses suggest that there may not be a threshold, or if one exists, it is somewhere in the range of 0 to 0.8 Gy. The excess cataracts seen are of the types generally associated with radiation: posterior subcapsular and cortical cataracts. Figure 1 shows the relation between radiation dose and cortical opacity of lens ...
TY - JOUR. T1 - Dose-dependent prevention of sugar cataracts in galactose-fed dogs by the aldose reductase inhibitor M79175. AU - Sato, Sanai. AU - Mori, Kazuhiko. AU - Wyman, Milton. AU - Kador, Peter F.. PY - 1998/2. Y1 - 1998/2. N2 - Sugar cataracts rapidly develop in dogs fed a diet containing 30% galactose. While studies on the formation and progression of these sugar cataracts suggest that they are osmotic in nature and are linked to aldose reductase, sugar cataract formation in the dog to date has not been completely prevented by the administration of aldose reductase inhibitors sorbinil and M79175. To demonstrate that the formation and progression of sugar cataracts in galactose-fed dogs can be dose-dependently inhibited by the administration of aldose reductase inhibitors, 9-month old male beagles were placed on diet containing 30% galactose with/without 10 or 16 mg kg-1 day-1 of M79175 for up to 39 months. Cataract progression in all dogs was followed by periodic slit lamp examination ...
A surface treated intraocular lens implant for use in the replacement of a cataractous natural lens to prevent posteriror capsular opacification. The surface treated intraocular lens includes one or more proteins, polypeptides, polyamino acids or polyamines bound to the surface of the intraocular lens implant covalently, non-covalently or a combination thereof. The one or more proteins, polypeptides, polyamino acids or polyamines present on the surface of the intraocular lens implant serves to reduce or eliminate residual lens epithelial cell migration within the lens capsule. By preventing residual lens epithelial cell migration, posterior capsular opacification of the intraocular lens implant is thus reduced or eliminated.
Stenotrophomonas maltophilia endophthalmitis following cataract surgery: clinical and microbiological results Jonathan S Chang, Harry W Flynn Jr, Darlene Miller, William E Smiddy Department of Ophthalmology, Bascom Palmer Eye Institute, Miller School of Medicine, University of Miami, Miami, FL, USA Background: Stenotrophomonas maltophilia is a Gram-negative organism known to cause opportunistic infections. It is a rare source of endophthalmitis, often in the setting of trauma, but has been reported following cataract extraction. The purpose of this study was to evaluate antimicrobial sensitivities, clinical characteristics, and treatment outcomes in patients with endophthalmitis caused by S. maltophilia following cataract extraction. Methods: A retrospective case review of records from January 1, 1990 to June 30, 2010 was performed at the Bascom Palmer Eye Institute. Results: Eight cases of S. maltophilia endophthalmitis were identified following cataract surgery. Initial visual acuity ranged from 20
Manual Small Incision Cataract Surgery also known as manual phaco or MSICS or SICS. This is the most cost effective cataract cataract extraction method with consistent very good visual outcome.We are demonstrating a real small incision 5.5 mm in this video. (You have seen a lot of SICS video at youtube but there incision size more than 8 mm). All types of cataracts (hard cataract,posterior polar cataract, mature cataract, hypermature cataract) can be operated by this method. Because we are breaking nucleus in the tunnel and taking out in the pieces. The breaking of the nucleus is done in the tunnel,so cornea is spared form the injury.
