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. ...

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 ...

In mice, mutations or targeted disruptions of the core circadian gene Bmal1 have been implicated in early onset of ocular pathologies, including premature/congenital cataract development. The aim of the present study was to analyze probands of consanguineous Pakistani cataract families to identify the novel pathogenic variants in the BMAL1 gene. We have studied 21 congenital cataract families. Ophthalmic examination was performed for the probands and available family members. Genomic DNA was isolated from peripheral blood. PCR and Sanger sequencing was performed for the entire coding region of the BMAL1 gene. Targeted Sanger sequencing of BMAL1 revealed a heterozygous variant c.41A>T; p.(Asp14Val) in one proband, but it did not co-segregate with the disease phenotype in the family. In addition, a nonsynonymous variant (rs2290037) was identified in five probands. Our study is the first one to analyze the role of BMAL1 gene mutations in humans for their association with congenital cataract. Although we
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 ...
In this article, we will share on a rare form of congenital cataract known as cerulean cataract.. Cerulean cataract (also known as blue-dot cataract) occurs where there are blue-white opacities in the lens cortex (middle layer of the lens). It can develop during childhood or occur at birth (congenital). The cause of cerulean cataract is due to mutation of several genes. It is of autosomal dominant inheritance (i.e. an affected individual has a copy of the mutant gene and a normal gene on a pair of non-sex chromosomes). The cataract can develop in 1 or both eyes and is progressive. Visual acuity is well-preserved, and surgery is usually not required before adult life.. Infants with cerulean cataract may be asymptomatic depending on the severity of the opacities. If severe, complications such as nystagmus (rapid involuntary movement of the eyes) and amblyopia (lazy eye) can develop. Both male and female can be equally affected. Family history of congenital cataract is one of the risk ...
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.. ...

A cataract is a clouding of the eyes natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world. Nuclear cataracts usually are associated with aging. Cataract development is a normal part of the ageing process, so everyone develops a degree of cataract as they get older. However, it can also occur at a younger age, where it may be related to a previous injury to the eye, medication use (such as steroids), or chronic illnesses such as diabetes.. When should I have cataract surgery?. Symptoms of a cataract might include hazy or blurred vision, light sensitivity and glare, feeling of a film over the eye, difficulty driving or reading, general loss of contrast with yellowing of vision.. Cataracts are diagnosed during a routine eye examination, and early on, they do not require surgical intervention. Often just changing your glasses will satisfy your visual needs. A cataract ...

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 ...

Cataracts are the clouding of the lens in the eye; its very common in older people. Over time, the cataract may grow larger and cloud more of the lens and may affect vision making it harder to see. Most cataracts are related to aging, smoking and diabetes. It can occur in either or both eyes.. The symptoms of early cataract may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. At later stages, surgery is the only effective treatment. A cataract needs to be removed when vision loss interferes with everyday activities, such as driving, reading, or watching TV. Surgery involves removing the cloudy lens and replacing it with an artificial lens.. Cataract removal is one of the most common operations performed in developed countries. It also is one of the safest and most effective types of surgery; about 90 percent of people who have cataract surgery have better vision afterward.. However, people in underdeveloped nations do not have access to such ...
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 ...
A cataract is a clouding of the lens within the eye. Your vision becomes blurred because the cataract is like frosted glass, interfering with your sight. Contrary to popular belief, cataract is not a layer of skin that grows over your eye.. If your doctor or optician has told you that you have a cataract, do not be alarmed. Many people over 60 have some cataract and the vast majority of these people can be successfully treated. Early cataracts may not affect your sight, and therefore do not require treatment.. If your cataract is impairing your vision, and is causing great annoyance or interfering with your daily routine, e.g. if you are a lorry driver and its affecting your driver vision, or if you enjoy arts and crafts such as needlework and can no longer do so, then you meet the criteria for being assessed for cataract removal. On the other hand if your vision is simply a little blurred but does not hinder your daily routine, you will be advised that there is no need for cataract ...
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 ...

Intraocular lens opacification after nonpenetrating glaucoma surgery with mitomycin-C. Intraocular lens opacification after nonpenetrating glaucoma surgery with mitomycin-C
We offer free Cataract seminars throughout the year with a Q&A session and one of the questions we hear often, is Will my cataract ever return after I have it removed? Many people are concerned about whether or not they will need to repeat cataract surgery on the same eye at a later date. Luckily, you can rest assured that you cannot get a cataract in the same eye after having cataract surgery. A cataract is the clouding of the eyes natural lens. In cataract surgery, the natural lens is removed and replaced with an artificial lens called an IOL. The new lens will not get cloudy. A small portion of cataract patients, experience a clouding of the lens capsule months or years after surgery. This occurs in the membrane or sac that used tohold the natural lens. This is called Capsular Opacification. Should this rare occurrence happen to you, it is easily treated by a YAG Laser Capsulotomy, a quick and painless procedure that can be done in our office in just a few minutes. If you have questions ...
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 ...
Congenital cataract is a major cause of visual impairment and childhood blindness. The solubility and stability of crystallin proteins play critical roles in maintaining the optical transparency of the lens during the life span. Previous studies have shown that approximately 8.3%∼25% of congenital cataracts are inherited, and mutations in crystallins are the most common. In this study, we attempted to identify the genetic defect in a four-generation family affected with congenital cataracts. The congenital cataract phenotype of this four-generation family was identified as membranous cataract by slit-lamp photography. Mutation screening of the candidate genes detected a heterozygous c.465G→C change in the exon6 of the βB2-crystallin gene (CRYBB2) in all family members affected with cataracts, resulting in the substitution of a highly conserved Tryptophan to Cystine (p.W151C). The mutation was confirmed by restriction fragment length polymorphism (RFLP) analysis and found that the transition

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 ...
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 ...
The impact of first and second eye cataract surgeries on falls: a prospective cohort study Ying Ru Feng,1,2 Lynn B Meuleners,2 Michelle L Fraser,2 Kate J Brameld,2 Seraina Agramunt2 1School of Population and Global Health, Faculty of Health and Medical Sciences, The University of Western Australia, Perth, WA, Australia; 2Curtin-Monash Accident Research Centre (C-MARC), Faculty of Health Sciences, Curtin University, Perth, WA, Australia Purpose: The purpose of this study was to investigate the impact of the first and second eye cataract surgeries on the risk of falls in participants with bilateral cataract and to determine which changes in visual measures are associated with changes in the number of falls throughout the cataract surgery process.Patients and methods: Fifty-five older adults with bilateral cataract aged 55+ years were assessed at three time points during the cataract surgery process, and they completed a falls diary. Two separate generalized estimating equation–negative binomial
Cataract surgery in infantile eyes, which are microphthalmic, can be even more demanding.. In addition, the frequent presence of other ocular and systemic anomalies such as nystagmus, glaucoma, amblyopia, and higher rate of postoperative complications may limit the success of cataract surgery.. In our previous study, the investigators examined the intraoperative performance and postoperative outcomes of bilateral cataract surgery in microphthalmic eyes of patients before their first birthday. At 1 year, the postoperative results showed that good visual outcomes could be obtained in microphthalmic eyes.. Since only a few studies have reported outcomes, and that too only short term of cataract surgery on microphthalmic eyes, in this prospective observational study we evaluated the long-term impact of bilateral cataract surgery on eyes with microphthalmos. The investigators examined the outcomes, complication rates, influence of age at surgery on pattern of axial growth and central corneal ...
The demand for cataract surgery is set to increase due to the ageing population of Australia. Cataracts are usually bilateral, but cataract surgery is almost always performed one eye at a time. Previous investigations of the impact of cataract surgery seldom analysed the separate effects of each surgery. Instead, patients who underwent first, second or both eye surgeries were combined in the analyses. In Western Australia, public hospital patients wait substantial periods of time between first and second eye cataract surgeries. For these patients, understanding the separate effects of first eye surgery on driving difficulty, vision-related quality of life and depressive symptoms is of considerable importance for their safety and well-being.This before and after study aimed to gain a better understanding of the impact of first eye cataract surgery on self-reported driving difficulty, vision-related quality of life and depressive symptoms for older drivers. It also aimed to investigate how changes ...
Presenile cataract may present in the second to fifth decades and can be associated with genetic or metabolic disorders, including myotonic dystrophy-associated cataract, hereditary hyperferritinemia cataract syndrome (HHCS), adult i blood group phenotype, female carriers of X-linked forms of cataract (eg, Nance Horan cataract-dental syndrome [NHS]; Lowe oculocerebrorenal syndrome [OCRL]), oil droplet cataract and diabetic cataract. Other adult-onset forms of cataract may result from local ocular disease (eg, uveitis, retinal dystrophy or degeneration, glaucoma, ocular tumors), certain drugs (eg, chronic corticosteroid regimens), radiation exposure, electrocution, metal ion deposits (eg, siderotic cataract), and trauma. ...

Background and objectives: This study was aimed to evaluate the incidence, age and sex distribution, aetiology, prognostic indicators, various complications associated with traumatic cataract and to determine final visual outcome of various treatment modalities. Methods:- In this prospective study 40 traumatic cataract patients were identified, then pre-operatively evaluated and had underwent surgery for cataract with or without intraocular lens implantation for a period from April 2015 to October 2016 at S.S.G. Hospital, Vadodara (India). All the patients were followed for a period of one and half months. Determinants of the visual acuity were compared between traumatic cataract due to open globe and closed globe injuries. Incidence of traumatic cataract with characteristics like age, sex, cause of injury, mode of injury, management of complications and visual outcome after management were analyzed and results interfered. Results: From the present prospective study enrolling 40 patients the ...
Cataract is a common ophthalmic disorder and the leading cause of blindness worldwide. While cataract is cured via surgical procedures, its impact on iris based biometric recognition has not been effectively studied. The key objective of this research is to assess the effect of cataract surgery on the iris texture pattern as a means of personal authentication. We prepare and release the IIITD Cataract Surgery Database (CaSD) captured from 132 cataract patients using three commercial iris sensors. A non-comparative non-randomized cohort study is performed on the iris texture patterns in CaSD and authentication performance is studied using three biometric recognition systems. Performance is lower when matching pre-operative images to post-operative images (74.69 ± 9.77%) as compared to matching pre-operative images to pre-operative images (93.42 ± 1.76%). 100% recognition performance is observed on a control-group of healthy irises from 68 subjects. Authentication performance improves if cataract

What is a cataract?. A cataract is a clouding of the eyes lens that causes loss of vision. This brochure is about age-related cataract, the most common type.. What causes it?. The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded. The lens also adjusts the eyes focus, letting us see things clearly both up close and far away.. The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light 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. Over time, the cataract may grow larger and cloud more of the lens, making it harder to see.. Researchers suspect that there are several causes of cataract, such as smoking and diabetes. Or, it may be that the protein in the lens just changes from the wear and tear it takes over the years ...
Purpose: To determine the impact of cataract surgery on visual functions (VFs) and quality of life (QoL) in patients with cataract at the National Eye Center, Kaduna. Methods: VFs and QoL questionnaires were administered to the patients preoperatively and 6 weeks postoperatively. Correlation was assessed among subjective VF, QoL, and visual acuity (VA). The preoperative and sixth-week postoperative VA, VF scores, and QoL scores were compared. A paired t-test was used for comparison between before and after surgery. Results: Two hundred and seventy-one patients were studied. The age range of the patients was 45 to 85 years with a mean age of 64.2 years (SD ± 6.51). There was significant improvement in overall VF and QoL following cataract surgery (P,0.0001). Mean VF scores preoperatively and at 6 weeks postoperatively were 28.6 (SD ± 7.9) and 15.1 (SD ± 3.5), respectively. The overall mean QoL scores were 23.7 (SD ± 9.0.) preoperatively and 13.5 (SD ± 1.1) postoperatively. This difference ...

Cataracts are defined as opacities of the eye lens and can be caused by a large number of risk factors. In aquaculture, cataracts in farmed Atlantic salmon (Salmo salar L.) represent an ethical problem and can cause economical losses. A series of studies have shown the cataract mitigating effect of dietary histidine (His) levels above the currently recommended minimum requirement in Atlantic salmon smolt and that dietary His levels are reflected in the concentrations of the His-derivative Nacetylhistidine (NAH) in the lens. However, the mechanism of lens protection by dietary His is not clear and no studies with adult Atlantic salmon growers have previously been carried out. Gene expression analysis in the lens is a powerful tool to investigate the molecular mechanisms of cataract formation in Atlantic salmon. In an initial study, the possible effects of different sampling procedures and tissue preservation methods on lens gene expression and lens RNA quality were investigated. Although there ...

At that point, you may need cataract surgery - a standard procedure that is very effective. [acronymattic.com] After discussion with the patients family, the decision was made not to perform cataract surgery because of the poor visual prognosis. With a successful surgery, long-term patching is necessary to complete the process of restoring vision. Many patients receiving a monofocal lens need a spectacle correction to achieve their best acuity following cataract surgery. 11. After ...
Background: Noma (cancrum oris) remains the scourge of children and the face of poverty in Sub-Saharan Africa. Recent data on the burden of noma and its risk factors are needed for evaluating and redesigning interventions for its prevention and control. Objectives: This study aimed to determine the pattern of noma and its risk factors in Northwestern Nigeria. Materials and Methods: It was a retrospective study that looked into cases of noma (cancrum oris) admitted into the Noma Children Hospital, Sokoto, Nigeria, between January 1999 and December 2011. Information on patients bio-data, the site and severity of lesions, and presence of trismus and its severity were extracted from the patients case files and analyzed using descriptive statistics. Results: One hundred and fifty-nine (8.3%) of the 1923 patients admitted to the hospital from January 1999 to December 2011 were diagnosed with fresh noma. The mean age of the patients was 3.0 ± 1.4 years, and majority of them, 139 (87.4%) were aged ...

First eye cataract surgery significantly reduced patient falls, although major changes in the dioptric power of spectacle correction of the operated eye after surgery increased fall risk, reported Anna Palagyi, PhD, and fellow researchers. Their prospective cohort study included patients who had bilateral cataract, were aged 65 and older, and were on public hospital cataract surgery waiting lists in Australia. Of the 329 patients who were recruited, 66.6% had first eye surgery in the study period. The first eye cataract surgery reduced incident falls by 33%; poorer dominant eye visual acuity was associated with falls during the study timeline. Those who had a larger than ±0.75 spherical equivalent diopter change had a two-fold greater incidence of falls after first eye cataract surgery compared with those with less or no change in lens power. The researchers recommended cautious postop refractive management to maximize the benefit of cataract surgery as a fall prevention measure. The research ...
American Academy of Ophthalmology: August 2006 - A number of medical associations including the American Academy of Ophthalmology, the American Society of Cataract & Refractive and the American Urological Association have warned patients that the common prostrate drug, Flomax, and similar medications known as alpha-blockers may cause problems during cataract surgery. If you are taking Flomax and plan on having cataract surgery it is important that you alert your cataract surgeon before you have your surgery.. Flomax, commonly used to treat an enlarged prostate, and other alpha-blockers such as Hytrin, Cardura and Uroxatral can cause abnormal movement of muscles controlling the opening and closing of the iris and thus can interfere with pupil dilation, creating a condition known as intraoperative floppy iris syndrome. Your cataract surgeon will take extra precautions including additional eye drops if you are taking these medications in order to prevent unexpected complications during cataract ...
Cataracts are cloudy patches that develop in the lens of your eye and can cause blurred or misty vision. In many cases, cataracts are age-related, appearing first when a person is in his or her 40s or 50s, but not affecting vision until after age 60. Cataract surgery is the only treatment available while medical treatment is often provided but has proven to be not very effective. A safe and effective new technique is needed to improve patients vision, especially for those with mild and moderate cataracts. Iontophoresis is a non-invasive technique in which a small electric current is applied to increase drug penetration into the tissues. The advantages are that it is easy to use and there are no systemic side effects. Based on the principle of iontophoresis, Suzhou Liu Liuliu Vision Science and Technology Co. developed a method to deliver traditional Chinese medicine with the iontophoresis device. Early results show that vision is improved after 4 weeks application of the treatment. The device ...

Despite recommendations for greater use of second-eye cataract surgery and the bilateral progression of the disease, there is a substantial proportion of unmet need for this treatment. Few studies have explored the factors associated with second-eye cataract surgery utilisation. The objective of our study was to estimate the proportion of second-eye cataract surgery, evaluate its time-trend, and explore differences in utilisation by patients gender, age, and region of residence. All senile cataract surgeries performed between 1999 and 2002 in the public health system of Catalonia (Spain) were obtained from the Minimum Data Set. The proportion of second-eye surgery from November 2000 to December 2002 was calculated. The time-trend of this proportion was characterised through linear regression models with the logarithmic transformation of time. The proportion of second-eye surgery was 30.0% and showed an increasing trend from 24.8% (95% Confidence Interval [CI] 21.6; 26.1) in November 2000 to 31.8% (95%

In spite of amazing technical progress, cataracts remain the leading cause of blindness in the world, affecting almost half (45%) of the 40 to 45 million blind people worldwide according to the WHO, this number increases to 180 million when people with «visual deficiency» are included [9, 10].. Evidently, cataracts pertain to the 80% of cases of blindness that are considered avoidable and, in developed countries, they are no longer a major cause of irreversible blindness. Nowadays, for example, cataracts are considered to be the principal pathology in not much more than 2% of the affiliates of ONCE (Spanish National Organization for the blind [11]). In spite of this, demographic growth and increase in life expectancy, growing more rapidly than the availability of modern surgical treatment in vast areas of the world, will cause cataracts to contribute considerably to the increase of the total number of blind people in the world, the number of whom is estimated to reach 100 million by about 2020 ...

The research team found that the HCV-infected patients were 1.36 times more likely to develop cataracts than non-HCV infected patients. Interestingly, patients who were undergoing a specific treatment with interferon-ribavirin therapy were at the greatest risk of developing cataracts. Using interferon-ribavirin therapy to treat HCV almost doubled the risk for developing cataracts compared to patients who were not infected with HCV. After the research was compiled, the researchers did not discourage the use of interferon-ribavirin therapy even though this treatment increased risk of cataract development ...

When cataracts encroach on the eyes, the only effective remedy is to surgically replace the eyes lenses with synthetic substitutes.. But what if scientists found a way to delay or prevent cataracts from forming in the first place?. Researchers at the University of Delaware may have found such an opportunity by identifying the prime suspects in the formation of cataracts - deficiency of two genes that encode regulatory proteins. When those two genes are unable to do their work, the lenses of the eyes become cloudy and develop cataracts, no aging process or damaging exposure to radiation required. Cataracts, the leading cause of blindness, can have a genetic basis.. The discoveries emerged in the laboratory of UD biologist Salil Lachke, assistant professor of biological sciences and a Pew Scholar in biomedical sciences. Lachke and graduate students Smriti Agrawal, Archana Siddam and post-doctoral fellow Deepti Anand study lens development in mice to better understand the genetic mechanisms that ...
Previous studies have shown that lenticular levels of Fe and Cu are elevated in age-related cataract. However, it is not known if these metals are present in a state that is permissive for redox reactions that may lead to the formation of free radicals. In addition, there is little data available concerning the concentration and lenticular distribution of ferritin, the major intracellular Fe-sequestering protein, in the lens. The aim of the present work was therefore to determine the distribution of ferritin and the redox-availability of Fe and Cu in healthy and cataractous lenses. Lens ferritin distribution was assessed by ELISA and immunohistochemistry. A modified ELISA detected ferritin in an insoluble lens protein fraction. Ferritin levels were not significantly different in the cortex vs nucleus of healthy lenses. In contrast, ferritin levels in the cataractous lens nuclei appeared to be 70 % lower compared to the cortex. This was at least partially due to the presence of ferritin within ...
Mean spherical equivalent (SE) dropped from -18.32±2.37 diopters (D) preoperatively to -0.88±0.52D 5-years postoperatively. The mean Snellen decimal BCVA and UCVA were 0.73±0.23 and 0.55±0.26, respectively. More than 50% of eyes achieved 20/25 or better BCVA postoperatively. The safety index was 1.26±0.32. Forty eyes (65.5%) had UCVA of 20/40 or better postoperatively. The efficacy index was 0.99±0.42. Mean central vault was 475.28±216.38µm postoperatively. No eyes showed central contact between ICL and crystalline lens. Nevertheless, 10 eyes showed peripheral contact; with a central vault between 150 and 260µm. Two eyes developed anterior subcapsular cataract, although just one eye required cataract surgery ...
