Phenotype of autosomal recessive congenital microphthalmia mapping to chromosome 14q32. (1/277)

BACKGROUND: Congenital microphthalmia (OMIM: 309700) may occur in isolation or in association with a variety of systemic malformations. Isolated microphthalmia may be inherited as an autosomal dominant, an autosomal recessive, or an X linked trait. METHODS: Based on a whole genome linkage analysis, in a six generation consanguineous family with autosomal recessive inheritance, the first locus for isolated microphthalmia was mapped to chromosome 14q32. Eight members of this family underwent clinical examination to determine the nature of the microphthalmia phenotype associated with this locus. RESULTS: All affected individuals in this family suffered from bilateral microphthalmia in association with anterior segment abnormalities, and the best visual acuity achieved was "perception of light". Corneal changes included partial or complete congenital sclerocornea, and the later development of corneal vascularisation and anterior staphyloma. Intraocular pressure, as measured by Schiotz tonometry, was greatly elevated in many cases. CONCLUSIONS: This combination of ocular defects suggests an embryological disorder involving tissues derived from both the neuroectoderm and neural crest. Other families with defects in the microphthalmia gene located on 14q32 may have a similar ocular phenotype aiding their identification.  (+info)

A first British case of fish-eye disease presenting at age 75 years: a double heterozygote for defined and new mutations affecting LCAT structure and expression. (2/277)

Fish-eye disease is a familial syndrome with corneal opacification, major high density lipoprotein (HDL) deficiency in plasma, significant cholesterol esterification in plasma on non-HDL lipoproteins, generally without premature coronary disease. This first British male case from unrelated British parents had infarcts when aged 49 and 73 years but was asymptomatic at age 81 years, with plasma cholesterol 4.3-7.1 mmol/litre, triglycerides 1.8-2.2 mmol/litre, HDL cholesterol < 0.1 mmol/litre, apolipoprotein A-I < 0.16 g/litre, lipoprotein(a) 0.61 g/litre. Cholesterol esterification was impaired using HDL-3 and A-I proteoliposomes but not using VLDL/IDL/LDL. The findings are those of LCAT deficiency with the classic fish-eye disease defect. Most of the 22 reported cases were homozygous or heterozygous for a Thr-Ile mutation at codon 123 of the lecithin:cholesterol acyltransferase (LCAT) gene. This patient was a double heterozygote for this mutation and a second new incompletely defined mutation affecting LCAT expression as defined by reduced mass and activity in plasma.  (+info)

Functional human corneal equivalents constructed from cell lines. (3/277)

Human corneal equivalents comprising the three main layers of the cornea (epithelium, stroma, and endothelium) were constructed. Each cellular layer was fabricated from immortalized human corneal cells that were screened for use on the basis of morphological, biochemical, and electrophysiological similarity to their natural counterparts. The resulting corneal equivalents mimicked human corneas in key physical and physiological functions, including morphology, biochemical marker expression, transparency, ion and fluid transport, and gene expression. Morphological and functional equivalents to human corneas that can be produced in vitro have immediate applications in toxicity and drug efficacy testing, and form the basis for future development of implantable tissues.  (+info)

Persistent corneal haze after excimer laser photokeratectomy in plasminogen-deficient mice. (4/277)

PURPOSE: Excimer laser photorefractive keratectomy creates a nonvascular wound of the cornea. Fibrin deposition and resolution after excimer laser photokeratectomy were investigated in relation to corneal repair and restoration of clarity in mice with a genetic deficiency of plasminogen. METHODS: A Summit Apex Laser (Summit, Waltham, MA) was used to perform 2-mm, 175-pulse, transepithelial photoablations that resulted in deep stromal keratectomies. Photokeratectomy was performed on the corneas of plasminogen-deficient (Plg-/-) mice and littermate control animals. Eyes were examined for re-epithelialization and clarity throughout the 21-day observational period. Histologic sections were taken during the observational period and fibrin(ogen) was detected immunohistochemically. RESULTS: Re-epithelialization was rapid and complete within 3 days in both control and Plg-/- animals. Exuberant corneal fibrin(ogen) deposition was noted in Plg-/- mice and sparse fibrin(ogen) deposition in control mice on days 1 and 3 after injury. Fibrin(ogen) deposits resolved in control mice but persisted in Plg-/- mice (74% of eyes at 21 days; P < 0.004). Corneal opacification, scarring, and the presence of anterior chamber fibrin(ogen) occurred in plasminogen-deficient mice but not in control mice. CONCLUSIONS: Fibrin(ogen) deposition occurs during corneal wound repair after photokeratectomy. Impaired fibrinolysis in Plg-/- mice caused persistent stromal fibrin deposits that correlated with the development of corneal opacity.  (+info)

Relationship between structure and biochemical phenotype of lecithin:cholesterol acyltransferase (LCAT) mutants causing fish-eye disease. (5/277)

In order to test the hypothesis that fish-eye disease (FED) is due to a deficient activation of lecithin:cholesterol acyltransferase (LCAT) by its co-factor apolipoprotein (apo) A-I, we overexpressed the natural mutants T123I, N131D, N391S, and other engineered mutants in Cos-1 cells. Esterase activity was measured on a monomeric phospholipid enelogue, phospholipase A(2) activity was measured on reconstituted high density lipoprotein (HDL), and acyltransferase activity was measured both on rHDL and on low density lipoprotein (LDL). The natural FED mutants have decreased phospholipase A(2) activity on rHDL, which accounts for the decreased acyltransferase activity previously reported. All mutants engineered at positions 131 and 391 had decreased esterase activity on a monomeric substrate and decreased acyltransferase activity on LDL. In contrast, mutations at position 123 preserved these activities and specifically decreased phospholipase A(2) and acyltransferase activites on rHDL. Mutations of hydrophilic residues in amphipathic helices alpha 3;-4 and alpha His to an alanine did not affect the mutants' activity on rHDL. Based upon the 3D model built for human LCAT, we designed a new mutant F382A, which had a biochemical phenotype similar to the natural T123I FED mutant. These data suggest that residues T123 and F382, located N-terminal of helices alpha 3-4 and alpha His, contribute specifically to the interaction of LCAT with HDL and possibly with its co-factor apoA-I. Residues N131 and N391 seem critical for the optimal orientation of the two amphipathic helices necessary for the recognition of a lipoprotein substrate by the enzyme.  (+info)

Ocular changes in beagle dogs following oral administration of CGS 24565, a potential hypolipidemic agent. (6/277)

(11R)-N,15-dideoxo-1-deoxy-1,15-epoxy-11-hydroxy-4-0methy l-8-0-(2, 2-dimethyl-1-oxopropyl)-3-[4- inverted question mark(2,4, 6-trimethylphenyl)methyl inverted question mark-1-piperazinyl]rifamycin has been evaluated as a potential hypolipidemic agent. As part of a safety evaluation program, a 3-month oral toxicity study was performed in which CGS 24565 was administered to beagle dogs via gelatin capsules at 10, 50, or 300 mg/kg/day. Ophthalmoscopic examinations (using focal illumination and indirect opthalmoscopy) on day 83 (week 12) revealed bilateral adnexal and corneal changes affecting 5 dogs (3 males, 2 females, 300 mg/kg/day). Ophthalmoscopically, dogs from the 300 mg/kg dose level exhibited the adnexal changes characterized as ptosis, conjunctivitis, episcleritis, and relaxed membrane nictitans, while the corneal changes were characterized as posterior stromal edema (cloudy, diffuse opacity usually accompanied by deep neovascularization; the diffuse edema masked the complete evaluation of other ocular structures) and stromal infiltrates in the area of Decement's membrane (appeared to be multifocal, polymorphic changes/alterations in Decement's membrane, or endothelial swelling). No changes from normal were seen clinically in the eyes of other dogs on this experiment. In those dogs affected by the ocular changes caused by CGS 24565, a visual deficit in acuity was suspected. The corneal changes, as manifested, were suggestive of permanent, irreversible corneal damage. Subsequent ophthalmoscopic examinations performed at established intervals during weeks 15 through 26, revealed abatement of the adnexal changes, while the corneal changes, as described above, remained generally unchanged, confirming irreversibility of the corneal changes within the recovery period of 13 weeks. Light microscopy confirmed irreversible corneal neovascularization, vacuolar degeneration of the keratocytes at 300 mg/kg, and polymorphic infiltrates in the region of Decement's membrane. The results demonstrate that the cornea was the target tissue of toxicity for CGS 24565, and indicated that the findings represent a significant toxic effect. The correlation of histopathological findings support the hypothesis of the diagnosis of interstitial stromal degeneration/atrophy. The potential for a similar result to the cornea of humans does exist. Due to these changes and other toxic effects associated with this class of compound, further development was terminated.  (+info)

A simple method to evaluate the massive dose vitamin A prophylaxis program in preschool children. (7/277)

A massive dose vitamin A prophylaxis program is currently in operation in several States of India. Evaluation of this program on a large scale has so far been difficult due to lack of baseline data on the prevalence of vitamin A deficiency in children. In this study, a simple evaluation method which makes use of the linear relationship that exists between age on one hand and prevalence of ocular signs of vitamin A deficiency (Bitot's spots) on the other is described. Regression coefficients between age and prevalence of vitamin A deficiency of areas not covered by the program (control areas) were found to be significantly different both from zero and from regression coefficients of regularly covered areas (experimental areas). Also, all regression lines of control areas were found to be above the regression zone of experimental areas. These differences between the experimental and control areas which were significant, indicate the impact of the program in areas where the program is in operation. The regression coefficient calculated for one area where the program was discontinued after some time was found to be significantly different from zero, also it was different from the regression zone of the experimental areas. However, the regression coefficient of the discontinued area was found to be significantly different from the experimental areas only at 10% level, indicating a lesser degree of efficiency of the program in this area as compared to regularly fed areas. It is, therefore, suggested that evaluation of the massive dose prophylaxis program be done against the null hypothesis beta = 0.0065--the regression coefficient achievable under field conditions.  (+info)

Excimer laser phototherapeutic keratectomy: indications, results and its role in the Indian scenario. (8/277)

PURPOSE: To report indications, technique, and results of excimer phototherapeutic keratectomy (PTK), and describe possible reasons for the small numbers of such procedures performed in a referral institute in India. METHODS: Retrospective review of case records of 10 patients (11 eyes) who underwent excimer PTK at our institute between February 1994 and September 1997. RESULTS: Corneal scars were the most common indication for treatment. Best-corrected visual acuity (BCVA) improved in 6 eyes (mean: 2 lines of Snellen acuity). All eyes had BCVA > or = 6/12 after treatment. None of the patients experienced loss of BCVA after treatment. Unaided visual acuity improved in 3 eyes and decreased in 2 eyes. Change in spherical equivalent refraction > or = 1 diopter occurred in 77.8% of eyes after treatment. Treating central corneal scars resulted in a significant hyperopic shift in refraction. CONCLUSIONS: Excimer PTK is a safe and effective procedure for the treatment of superficial corneal opacities. Post-treatment ametropia may require further correction with optical aids. Inappropriate referrals, deep corneal scars, and cost of the procedure could have contributed to the small numbers of PTK performed at our institute. Improved understanding of procedural strengths and limitations could lead to increased use of this procedure, with satisfying results in selected patients.  (+info)

Helpful, trusted answers from doctors: Dr. Cremers on alternative treatments for corneal opacity: First, it is best to try to identify and treat the underlying disease process, so that the inflammatory impetus to form new vessels is reversed or minimized. If there is a quiet eye, there are a couple possible treatment options. First, laser ablation of the vessels has had some success, especially using a yellow dye laser. Second, a medicine that makes new blood vessels disappear can be injected.

In this series of patients with corneal opacification secondary to trauma and coexisting vitreoretinal pathologies, combined PPV and PK surgery performed with Landers wide-angle keratoprosthesis resulted in retinal attachment in 6 cases (75%), normotony in 5 cases (62.5%), and graft transparency in 5 cases (62.5%). VA did not decrease in any of the cases, increased in 5 cases (62.5%), and was unchanged in 3 cases. In total, 4 cases (50%) were considered completely successful.. Various alternatives have been used in attempts to perform posterior segment surgeries in eyes with corneal opacities. The main alternatives are performing PK followed by PPV in a separate session, performing simultaneous open sky vitrectomy with corneal excision, or performing PPV with endoscopic methods or temporary keratoprostheses.6. When PK and PPV surgeries are performed in separate sessions, PPV may be delayed due to risks such as persistent corneal edema or graft rejection. Moreover, it has been reported that fluid ...

Unfortunately, stromal haze is more commonly associated with higher ablation depths. The surgeon applies mitomycin C 0.02% for 12 seconds after the laser ablation to effectively mitigate corneal haze for eyes at greatest risk, including those with ablations greater or equal to 6.00 D or greater than 75 μm.. Other measures to prevent haze are somewhat anecdotal, but an extended course of oral vitamin C, oral steroids and a four-month tapering of steroids postoperatively may also prevent haze formation. More importantly, given the relationship between UV exposure and corneal haze, even one to two years after surgery, ophthalmologists should emphasize protection from and limited exposure to UV radiation. Other important considerations unique to advanced surface ablation can be drawbacks in the immediate postoperative period. In my experience, the recovery of the final visual acuity for higher myopic ablations is more protracted, and can take upwards of two to three months to achieve ...
KLEIP co-localizes transiently with E-cadherin in cultured MDCK cells, suggesting that it regulates formation of cell-cell contacts. 18 Therefore, we hypothesized that E-cadherin localization could be altered in the epithelium of KLEIP-deficient corneas, and expression of E-cadherin in KLEIP+/+ and KLEIP−/− mice was examined. In KLEIP+/+ corneas, both epithelial cell layers, namely the squamous cell layer and the basal cell layer, were positive for E-cadherin, and both layers displayed the physiologic architecture (Fig. 5A, left). In contrast, squamous and basal cell layers in KLEIP−/− mice largely were disorganized and characterized by acellular areas in the squamous cell layer, suggesting loosened cell-cell contacts and an incomplete regeneration of the corneal epithelium in KLEIP−/− corneas (Fig. 5A, right). Furthermore, corneas of KLEIP−/− mice displayed several apoptotic cells, which were absent in KLEIP+/+ corneas (Fig. 5B). This observation suggested that high ...

Like I announced here, my Holga 120GN was upgraded to make some 60 pictures with a nonperforated 35mm roll (brand General Photo). I made a mask that used the entire width of the roll (35mm) and about 24mm of the lenght. Because the normal lens act as a weak tele, 60mm focal lenght instead of the normal 50mm for a 35mm full frame, I thought about using a wide angle lens to turn the modified Holga into an almost normal camera. Yes, it worked, and I also used a fish eye lens but it distorts too much the pictures. The wide angle lens are 0.5 x, so, instead of 60mm we have a 30mm focal lenght which allows further reduction of the picture. I will use this possibility to make a smaller mask and let margins in the film. The new size will be then 30x20 mm with 2,5mm margin on each side. This is exactly in the same proportion 3:2 of the normal 35mm full frame but the 30mm focal lenght is still a weak wide angle lens, maybe 0.6 or 0.7 ...

Congenital stromal corneal dystrophy (CSCD), also called Witschel dystrophy, is an extremely rare, autosomal dominant form of corneal dystrophy. Only 4 families have been reported to have the disease by 2009. The main features of the disease are numerous opaque flaky or feathery areas of clouding in the stroma that multiply with age and eventually preclude visibility of the endothelium. Strabismus or primary open angle glaucoma was noted in some of the patients. Thickness of the cornea stays the same, Descemets membrane and endothelium are relatively unaffected, but the fibrills of collagen that constitute stromal lamellae are reduced in diameter and lamellae themselves are packed significantly more tightly. CSCD is associated with a mutation in the gene DCN that encodes the protein decorin, located at chromosome 12q22. The disorder is inherited in an autosomal dominant manner, which indicates that the defective gene responsible for a disorder is located on an autosome (chromosome 12 is an ...
Results Overall, 12 113 of 12 899 people (93.9% response rate) were examined during the household visits. Prevalence of corneal disease was 3.7% (95% CI 3.4% to 4.1%) and that of corneal blindness was 0.12% (95% CI 0.05% to 0.17%). Multivariable analysis demonstrated that corneal disease was significantly higher in the elderly (p,0.0001) and illiterates (p,0.0001). Common causes of corneal opacity in the study population were pterygium (34.5%), ocular trauma (22.3%) and infectious keratitis (14.9%). Corneal diseases contributing to blindness were post-surgical bullous keratopathy (46.2%) and corneal degenerations (23.1%).. ...

Calcific band keratopathy (CBK) is a degenerative condition resulting in the deposition of calcium salts in the superficial layers of the cornea and causing significant visual disturbance and pain of the affected eye. The amount of CBK precipitates recovered from the affected eye is very small rendering a great challenge in development of an effective and non-invasive treatment for this condition. This provides an impetus to study the possible chemical factors that may contribute to the development of CBK in an effort to develop a more efficient and un-intrusive treatment for this condition. To this end, we have developed an in-vitro model system resembling band keratopathys chemical composition and morphology thus providing insight to the mechanism of formation and allowing for mass production of the material furthering the advances of therapeutic targeting CBK. Our study is the fIrst to demonstrate that low molecular silicon can assist in the formation of CBK. Given the predominance of ...
In those patients requiring vitreoretinal surgery and presenting opacity or corneal irregularity that prevents proper display, the use of a temporary keratoprostheses (QPT) is currently the best option. The QPT, implemented after trepanation of the opaque cornea, vitreoretinal surgery allows a correct visualization of intraocular structures. Once the vitreo-retinal surgery has been completed, the keratoprosthesis is removed and placed suture and corneal graft. In this way you can perform both procedures in a single surgical time, optimizing maneuvers in the vitreous space. The indication of this complex procedure is any vitreoretinal pathology whose surgery can not be performed by corneal opacity which is not medically treatable and prevents sufficient preoperative visualization. The vast majority of candidates for this surgery are from ocular trauma but I will present these cases that had severe endophthalmitis with severe infection and corneal opacity not permitting vitreoretinal surgery ...
TY - JOUR. T1 - Tgfβ mediated corneal myofibroblast transformation is dependent on tyrosine phosphorylation. AU - Jester, J. V.. AU - Huang, J.. AU - Kao, W. W.. AU - Petroll, Walter M. AU - Cavanagh, Harrison D. PY - 1997/12/1. Y1 - 1997/12/1. N2 - Recent studies of the inhibitory effects of ROD peptides on TGFβ induced keratocyte transformation and a-smooth muscle-specific actin (a-SM) expression suggest the presence of an outside-in signal transduction mechanism involving interactions between fibronectin (FN) and the FN receptors, a5βl integrin. The purpose of this study was to identify the role of integnn-dependent tyrosine phosphorylation in regulating a-SM gene expression and ultimately myofibroblast development. Methods: Since cell culture in serum containing media mimics myofibroblast transformation, all experiments were carried out on freshly isolated rabbit keratocytes plated in defined, serum-free media. Cells were exposed to TGFR (1 ng/ml), GRGDdSP (50 uM), GRADSP (100 uM) or ...
Purpose : Numerous studies have demonstrated the essential roles of the peripheral nervous system as the neuroendocrine system, mediating the secretion of neuropeptides and/or neurotransmitters to suppress the excessive inflammatory reactions in autoimmune diseases, such as inflammatory bowel disease. We recently reported that loss of corneal nerve leads to corneal inflammation and the loss of neurogenic immune privilege. The purpose of this study was to evaluate the effect of vasoactive intestinal peptide (VIP) on innate immunity in denervated cornea. Methods : Trigeminal axotomy (TA) or sham procedure were performed in 6-8 week-old male BALB/c mice. Corneal opacity grading, immunohistochemistry (IHC) and corneal cytokine levels were determined 24 hours after 20μg of LPS instillation onto the cornea with or without TA and topical VIP treatment (more than N=3). Corneal opacity grading was as follows; grade 0: clear, grade 1: mild opacity, grade 2: moderate opacity, grade 3: severely dense ...

Current Research and Scholarly Interests Corneal opacity is a leading cause of blindness. Cornea transplantation is at high risk of rejection when there is pre-existing vascularization of the cornea and in pediatric patients. Cornea transplant shortage remains a worldwide problem with millions on waitlists. Our laboratory is developing multiple strategies for treatment of corneal blindness. We are testing advanced materials and designs for keratoprostheses with the goal of reducing complications and easing surgical implantation. We are also developing intraocular electronic display prostheses for bypassing cornea opacity, a novel strategy that could allow for high quality vision without corneal clarity. ...

This is the story of two young men, brothers, residing in Dhakrani village of Block Vikasnagar in Dehradun district of Uttarakhand state in India. Mohammad Mustaqeem, 21 years and Abdurr Rehman, 18 years had been suffering with congenital corneal opacity since their births. Due to this condition, their corneas clouded progressively, with age, leading to decreasing vision. Apart from the ensuing visual impairment, they experienced other irritants in leading normal lifestyles; excessive tearing, constant sensation of something in the eye, and most disturbingly, excessive sensitivity to light, so much so that they could not comfortably put on their slippers, during the day, which were left in their homes courtyard. During evenings and night, their studies were hampered due to increasing sensitivity to light bulbs and tube lights. All in all, their lives were adversely affected, hampering their studies, social interaction and most of all their personal growth. However, despite their inherent ...
Thirty-one eyes (18 patients) were included. Subjective improvement was reported in 48.4% at T1. Differences were statistically significant between mean baseline BCVA (0.61; 95% CI=0.41-0.80), compared to T1 (0.51; 95% CI=0.29-0.72; p=0.04), T2 (0.49; 95%CI=0.28-0.70; p=0.004), and T3 (0.48; 95% CI=0.27-0.69; p=0.01). Mean epithelial defect at P0 was 52%±48% and 10%±7% at T1 (p=0.13). KNV was observed in 25.8% at P0 and T1, T2:19.3% and T3:6.4% (p=1.0). Corneal opacity at P0 was 29.03%, T1:18.52%, T2:14.29%, and T3:38.46% (p=0.33). Average SI at P0 was 1.08±0.75, T1:0.85±0.83, T2:0.98±0.84, and T3:0.61±0.54, without significant differences between P0-T1 (p=0.27 ...

Pharmaceutical companies can use in vitro testing for assessing worker safety. Pharmaceutical intermediates should be evaluated to determine the primary hazards associated with them so that those involved in the manufacturing process can take necessary precautions to avoid hazardous exposures.. Pharmaceutical compounds can vary widely in their physical forms, such as powders, liquids, and creams. Many in vitro assays such as those using 3-dimensional tissue constructs, and the Bovine Corneal Opacity and Permeability (BCOP) Assay, are suitable for testing different test article forms, and can provide predictions on the hazards associated with them. Testing can be structured by taking a tiered-testing approach depending on the expected irritation levels of the products, and using the protocol best suited for the test material. This could help to eliminate unnecessary testing. Protocols that align with OECD test guidelines for classification according to GHS hazards can be used, or companies may ...

Can ocular changes be detected early in children and adolescents with type 1 diabetes mellitus without retinopathy by using optical biometry and optical coherence tomography?
The saturation of visual scene decreases by haze due to environments (e.g. fog) and optical properties of eyes (e.g. aging of crystalline lens). However, we would be able to maintain stable colorfulness perception of a scene if we have a mechanism to compensate deceased saturation by haze. We previously examined the influence of haze on the colorfulness perception of natural images using foggy filters, and showed that it was almost the same with and without the foggy filters even immediately after wearing the filters, suggesting a strong instantaneous colorfulness compensation mechanism (ICVS2015). Here, we further examine if the strength of colorfulness compensation is influenced by the pattern of stimuli. We tested conditions viewing natural images through actual foggy filters as well as simulated images, using a colorfulness matching method. Observers memorized the colorfulness of a stimulus image without foggy filters. Then they adjusted the colorfulness of a natural image through foggy ...

Lecithin cholesterol acyltransferase deficiency (LCAT deficiency) is a disorder of lipoprotein metabolism. The disease has two forms: Familial LCAT deficiency, in which there is complete LCAT deficiency, and Fish-eye disease, in which there is a partial deficiency. Lecithin cholesterol acyltransferase catalyzes the formation of cholesterol esters in lipoproteins. Symptoms of the familial form include visual impairment caused by diffuse corneal opacities, target cell hemolytic anemia, and renal failure. Less common symptoms include atherosclerosis, hepatomegaly (enlarged liver), splenomegaly (enlarged spleen), and lymphadenopathy. Fish-eye disease is less severe and most commonly presents with impaired vision due to corneal opacification. It rarely presents with other findings, although, atherosclerosis, hepatomegaly, splenomegaly, and lymphadenopathy can occur. Carlson and Philipson found that the disease was named so because the cornea of the eye was so opaque or cloudy with dots of cholesterol ...
Congenital stromal corneal dystrophy is caused by mutations in the DCN gene. This gene provides instructions for making a protein called decorin, which is involved in the organization of collagens. Collagens are proteins that strengthen and support connective tissues such as skin, bone, tendons, and ligaments. In the cornea, well-organized bundles of collagen make the cornea transparent. Decorin ensures that collagen fibrils in the cornea are uniformly sized and regularly spaced.. Mutations in the DCN gene lead to the production of a defective version of decorin. This abnormal protein interferes with the organization of collagen fibrils in the cornea. As poorly arranged collagen fibrils accumulate, the cornea becomes cloudy. These corneal changes lead to reduced visual acuity and related eye abnormalities. ...
Fish-eye disease is caused by mutations in the LCAT gene. This gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT).. The LCAT enzyme plays a role in removing cholesterol from the blood and tissues by helping it attach to molecules called lipoproteins, which carry it to the liver. Once in the liver, the cholesterol is redistributed to other tissues or removed from the body. The enzyme has two major functions, called alpha- and beta-LCAT activity. Alpha-LCAT activity helps attach cholesterol to a lipoprotein called high-density lipoprotein (HDL). Beta-LCAT activity helps attach cholesterol to other lipoproteins called very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL).. LCAT gene mutations that cause fish-eye disease impair alpha-LCAT activity, reducing the enzymes ability to attach cholesterol to HDL. Impairment of this mechanism for reducing cholesterol in the body leads to cholesterol-containing opacities in the corneas. It is ...
Assessment of eye irritation hazard has long been a core requirement in any chemical legislation. Nevertheless, publications focussing on the eye damaging potential of nanomaterials are scarce. Traditionally, eye irritation testing was performed using rabbits. The OECD Test Guideline 437 Bovine Corneal Opacity and Permeability (BCOP) test method allows determining severely irritating substances without animals, and the recently adopted OECD Test Guideline 492 Reconstructed human cornea-like epithelium test method allows identifying chemicals that neither induce eye irritation nor serious eye damage. For substances applicable to these tests, huge progress has been made in replacing animal testing. The in vitro eye irritation potential of 20 nanosized and 3 non-nanosized materials was investigated in a 2-tier EpiOcular™ Eye Irritation Test (EpiOcular™-EIT) and BCOP testing strategy including histopathology of the bovine corneas. Furthermore, applicability of the testing strategy for nanomaterials was

Photorefractive keratectomy: measuring the matrix metalloproteinase activity and chondroitin sulfate concentration in tear fluid Tetsuya Mutoh, Masaya Nishio, Yukihiro Matsumoto, Kiyomi Arai, Makoto ChikudaDepartment of Ophthalmology, Dokkyo Medical University Koshigaya Hospital, Saitama, JapanAbstract: We herein report the case of a 20-year-old man who underwent a photorefractive keratectomy (PRK). We measured matrix metalloproteinase-9 (MMP-9) activity and chondroitin 4 sulfate and chondroitin 6 sulfate concentrations in tear fluid. Tear fluid was collected preoperatively via microcapillary tube, and was collected postoperatively on the first and fourth days, and after one week, one month, three months, and six months. Samples were formulated by dilution with 200 µL of saline. MMP-9 activity was analyzed by an enzyme immunocapture activity assay, and the concentrations of chondroitin sulfate were analyzed by enzyme-linked immunosorbent assay. No complications were observed after surgery, except for a
CORNEAL ABRASION Corneal abrasions, a cut or scratch of the clear window of the eye, are associated with light sensitivity, pain, and tearing. Corneal abrasions may cause mild discomfort or severe pain, depending on the size of the abrasion. Treatment may include lubrication, bandage contact lens, eye patching and/or preventative antibiotic ointment. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.. BAND KERATOPATHY Band keratopathy is a calcium deposit at the 3-9 oclock positions in the front layer of the cornea. This deposit of calcium may spread across the cornea in band like appearance. The condition is caused by inflammations, trauma, chronic ocular disease, or even systemic diseases.. Treatment is necessary when the deposits affect vision. If the band of calcium deposits affect visions, chemical removal can be considered. Usually, vision improves following the removal of calcium from the cornea.. CORNEAL DELLEN Dellen ...

Transboundary haze pollution affects about half of the countries in Southeast Asia with varied intensities on an almost annual basis. Haze not only affects visibility, but also causes widespread health problems, transportation disruptions, and other socioeconomic issues. This haze, and the fires that cause it, has been a key topic for environmental politics research in the region since the late 1990s. This has largely been driven by one overarching objective: how to prevent haze from returning in the following years. However, conditions on the ground (mostly in Indonesia and in the larger Southeast Asian region) have been changing and evolving drastically. This has resulted in a very dynamic research agenda that has to keep up with these changes.Within the context of environmental politics, fires and haze can be viewed through the broad lens of national interest. There is a strong link between the severity of haze and the burgeoning agribusiness sector in the region: that of oil palm in particular. Oil
Eye exams via a slit lamp are critical in screening for conditions such as cataracts, corneal opacities and pterygia early on to avert vision loss. The slit lamp, however, is a purely qualitative optical device that is bulky, expensive, can cause eye discomfort due to light sensitivity. It also requires a trained physician to operate, making it unsuitable for large-scale screening in resource-constrained settings. In this thesis, we propose a spectrum of portable anterior segment imaging solutions that can be operated by minimally trained health workers. On one end, we present a smartphone attachment with minimal optics and no electronic components beyond what is present in the smartphone itself to examine and image the anterior segment of the eye. This cost-effective, easily scalable solution would help extend the reach of anterior segment examination to extremely resource constrained settings, such as mass-screening camps, mobile ophthalmology clinics, war zones etc. On the other end, we ...
The red reflex test is used to screen for abnormalities of the back of the eye (posterior segment) and opacities in the visual axis, such as a cataract or corneal opacity. An ophthalmoscope held close to the examiners eye and focused on the pupil is used to view the eyes from 12 to 18 inches away from the subjects eyes. To be considered normal, the red reflex of the 2 eyes should be symmetrical. Dark spots in the red reflex, a blunted red reflex on 1 side, lack of a red reflex, or the presence of a white reflex (retinal reflection) are all indications for referral to an ophthalmologist.. Concern has been expressed recently that diagnosis of serious ocular conditions, including retinoblastoma and congenital cataract, in which early treatment is essential for future ocular and systemic health, often is not made sufficiently early to minimize potential consequences of those conditions. This concern has led to consideration of legislation in several statesa mandating early pupil-dilated red reflex ...

Appropriate visual assessments help identify children who may benefit from early interventions to correct or improve vision. Examination of the eyes and visual system should begin in the nursery and continue throughout both childhood and adolescence during routine well-child visits in the medical home. Newborn infants should be examined using inspection and red reflex testing to detect structural ocular abnormalities, such as cataract, corneal opacity, and ptosis. Instrument-based screening, if available, should be first attempted between 12 months and 3 years of age and at annual well-child visits until acuity can be tested directly. Direct testing of visual acuity can often begin by 4 years of age, using age-appropriate symbols (optotypes). Children found to have an ocular abnormality or who fail a vision assessment should be referred to a pediatric ophthalmologist or an eye care specialist appropriately trained to treat pediatric patients ...
Diabetic Retinopathy seen with OCT scan. B-Scan Ultrasound. B-Scan ultrasound is most useful when direct visualization of intraocular structures is difficult or impossible. Situations that prevent normal examination include lid problems, severe edema, corneal opacities, dense cataracts or hemorrhage. In such cases, diagnostic B-scan ultrasound can give valuable information on the status of the vitreous and retina.. Treatment and drugs. There now are many treatments for diabetic retinopathy, including lasers to the retina or miniscule injections of medications into the middle cavity of the eye. These procedures can be done in my office to prevent, treat, or reverse damage from diabetes in the retina.. Researchers have shown that eye injections, often but not always in combination with laser treatment, result in better vision than laser treatment alone for diabetes-associated swelling of the retina-the condition known as diabetic macular edema.. The key to these treatments is the blocking by eye ...
Eye Irritation: The primary eye irritation/corrosion potential of the test article was evaluated in New Zealand White Rabbits. The study was conducted in compliance with OECD GLP (1997). The test method was based on OECD No. 405 (2002), EC No. 440/2008, EPA OPPTS 870.2400 (1998) and JMAFF guidelines (2011). Single samples of approximately 64 mg of test article (a volume of approximately 0.1 mL) were instilled in the conjunctival sac of one of the eyes of each animal. The lids were held together for about one second to prevent loss of the test substance. The remaining untreated eye served as the control. The eyes were observed at 1, 24, 48, and 72 hours and 7 days after instillation. Immediately after the 24-hour observation, a solution of 2% fluorescein in water was instilled in both eyes of each animal to quantitatively determine corneal epithelial damage. Corneal opacity (maximum grade 1) and epithelial damage (maximum 35% of the corneal area) that had resolved within 72 hours was observed in ...
Skin irritation. Key study: A study was performed to assess the skin irritation potential of OS 2200 to the rabbit in accordance with OECD Guideline 404 (GLP study). Very slight to well-defined redness with or without very slight to slight swelling was seen in all three animals. This was accompanied by dryness and sloughing of the skin. These reactions resolved in all animals within 11 days of the exposure. The observed mean scores (24 -72h) for each animal were 2, 1.66 and 0.33 for erythema and 1.33, 0.66 and 0 for oedema. The test item was determined to be not irritating to the skin. Eye irritation. Key study: An ocular irritation study was performed according to EU method B.5 (GLP study). Corneal opacity was observed in all three animals. No irritation of the iris occurred. A diffuse crimson discoloration of the tissue surrounding the eye and lining the eyelids (conjunctiva) was noted in all three rabbits. This was accompanied by swelling and partial eversion of the eyelids in one animal. ...

Answer: A phthisical eye can grossly have the characteristic shrunken appearance that may be cuboidal in shape secondary to the pull of the rectus muscles on the soft globe. Retinal and ciliochoroidal detachments occur with hypotony, and the sclera can be markedly thickened. Even on CT scan, intraocular structures are not easily identifiable and there is often calcification seen within the eye. In phthisis bulbi, intraocular calcium may be deposited within band keratopathy, a cataractous lens, bony metaplasia of the RPE, sclera, a gliotic neural retina, or optic nerve ...

Journal of Refractive Surgery | ABSTRACTBACKGROUND: Excimer laser photorefractive keratectomy tor the correction of myopia is presently under investigation in the United States by the Food and Drug Administration (FDA). The Phase 1 1 -B FDA study is being conducted on 75 normally sighted myopic eyes utilizing three currently available excimer lasers. This report presents the 1 -year results on 12 myopic eyes treated with the
Background: Phototherapeutic keratectomy (PTK) has been employed as a surgical tool to treat corneal disease for more than 10 years. The laser has made it possible to remove superficial corneal opacities and thereby restore vision. The 193 nm ultraviolet light separates molecules and splits molecules in biological tissue, thereby ablating it. About 0.25 ╡m of tissue is ablated by each pulse. The development of the excimer laser technique has been fast. It has principally focused on refractive surgery but has also benefited PTK. Corneal dystrophies: The ability to delay or postpone corneal grafting in superficial corneal dystrophies represents a very important achievement. Map-dot-fingerprint dystrophy or basal membrane dystrophy is a common indication for PTK. Other dystrophies such as Meesmans, Reis-Bⁿcklers, Thiel-Benkes, granular, macular, lattice and Schnyders can be treated, although with differing degrees of success and varying rates of recurrence. Subepithelial scarring in Fuchs ...
If you have thin corneas and were told you were not a candidate for laser-assisted in situ keratomileusis, or LASIK (a corneal refractive procedure that requires the creation of a partial-thickness flap before the cornea is sculpted with a laser), PRK (Photorefractive Keratectomy) may be a good option for you ...
Lattice Corneal Dystrophy is associated with painful recurrent corneal erosions and amyloid corneal opacities induced by transforming growth factor β induced protein (TGFBIp) that impairs vision. The exact mechanism of amyloid fibril formation in Corneal Dystrophy is unknown but has been associated with destabilizing mutations in the fourth fasciclin 1 (Fas1-4) domain of TGFBIp. The green tea compound Epigallo-catechin gallate (EGCG) has been found to inhibit fibril formation of various amyloidogenic proteins in vitro. In this study we investigated the effect of EGCG as a potential treatment in Lattice Corneal Dystrophy (LCD) using Fas1-4 with the naturally occurring LCD-inducing A546T mutation. A few molar excess of EGCG were found to inhibit fibril formation in vitro by directing Fas1-4 A546T into stable EGCG-bound protein oligomers. Incubation with two molar equivalent EGCG led to a 4-fold reduction in the aggregates membrane disruptive potential, potentially indicative of significantly ...
PURPOSE: The present study was conducted to investigate healing of alkali-burned corneas in MRL/MpJ (MRL) mice. METHODS: Gross, clinical, and histologic criteria were used to compare healing of alkali-burned corneas in MRL and control C57BL/6J (B6) mice. Effects of neutrophil depletion of B6 mice and allogeneic reconstitution of B6 mice with MRL bone marrow on wound healing were evaluated. Gene expression patterns in normal and wounded corneas were surveyed with array-based quantitative real-time RT-PCR (AQPCR). RESULTS: MRL mice showed accelerated reepithelialization and decreased corneal opacity compared with B6 mice after alkali wounding. Marked inflammatory cell infiltration and fibrosis were evident in the corneas and anterior chambers of B6 mice. MRL mice showed less severe lesions, except for stromal edema. Rapid reepithelialization and reduced keratitis/iritis were also observed in neutrophil-depleted B6 mice, but not in B6 mice reconstituted with MRL bone marrow. AQPCR showed
Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal, and acanthamoeba keratitis), corneal opacity and scarring, keratoconus, bullous keratopathy, regrafting, corneal dystrophy and degeneration, herpes simplex keratopathy (active keratitis), etc. were considered as indications of corneal transplantation. Results: A total of 186 patients (110 males, 76 females) were included in the study. Mean age of patients was 47.7± 24.3 years (6-85). The leading indications of grafting was corneal opacity (32.3%) followed by keratoconus (22.6%), bacterial keratitis (15.6%), aphakic bullous keratopathy (6.7%), pseudophakic bullous keratopathy (6.5%), regrafting (4.8%), herpes
