Lattice corneal dystrophy type I is an eye disorder that affects the clear, outer covering of the eye called the cornea. The cornea must remain clear for an individual to see properly; however, in lattice corneal dystrophy type I, protein clumps known as amyloid deposits cloud the cornea, which leads to vision impairment. The cornea is made up of several layers of tissue, and in lattice corneal dystrophy type I, the deposits form in the stromal layer. The amyloid deposits form as delicate, branching fibers that create a lattice pattern.. Affected individuals often have recurrent corneal erosions, which are caused by separation of particular layers of the cornea from one another. Corneal erosions are very painful and can cause sensitivity to bright light (photophobia). Lattice corneal dystrophy type I is ...

Gelatinous drop-like corneal dystrophy, also known as amyloid corneal dystrophy, is a rare form of corneal dystrophy. The disease was described by Nakaizumi as early as 1914. The main pathological features in this dystrophy are mulberry-shaped gelatinous masses beneath the corneal epithelium. Patients suffer from photophobia, foreign body sensation in the cornea. The loss of vision is severe. The amyloid nodules have been found to contain lactoferrin, but the gene encoding lactoferrin is unaffected. This form of corneal amyloidosis appears to be more frequent in Japan. A number of mutations causing this disease have been described in the M1S1 (TACSTD2) gene encoding Tumor-associated calcium signal transducer 2, but not all patients have these mutations, suggesting involvement of other genes. Recurrence within a few years occurs in all ...
PURPOSE: To characterize the molecular defect in the TGFBI gene in a Chinese family affected with an atypical lattice corneal dystrophy.. DESIGN: Case report and experimental study.. METHODS: Molecular genetic analysis was performed on the DNA extracted from peripheral leucocytes from a Chinese family with atypical lattice corneal dystrophy. Fifty normal unrelated subjects of Chinese origin were used as controls. All exons of the TGFBI gene were amplified by polymerase chain reaction and directly sequenced.. RESULTS: Bilateral, symmetrical, ridgy round pattern of opacities with uneven surfaces and thin lattice lines were noted in the proband. Analysis of exon 14 revealed a heterozygous T to A transition on codon 625. The mutation was not detected in the unaffected family member and 50 unaffected individuals.. CONCLUSIONS: The novel TGFBI gene mutation (V625D) is associated with an early,onset variant of lattice ...
Purpose: This study was designed to investigate whether matrix metalloproteinases (MMPs) play a pivotal role in the development of TGFBI-Arg124Cys lattice corneal dystrophy type I (LCDI) using an ex vivo model of LCDI corneal epithelial cell cultures and corneal tissue excised from an LCDI patient.. Methods: To initially determine whether the dissolution of Bowmans layer is apparent in an LCDI affected cornea an H&E stain was carried out on sections of a corneal button excised from a patient suffering from TGFBI-Arg124Cys LCDI. Immunohistochecimstry (IHC) was also carried out to determine whether there is a localisation of MMPs around Bowmans layer. To confirm the induction of MMPs due to the presence of the TGFBI-Arg124Cys mutant allele qRT-PCR was carried out on LCDI corneal epithelial cultures and expression levels were compared to those ...

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. ...
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. ...

The insertional mutation of TACSTD2 that was found in 2 of the GDLD patients may have resulted from a flame-shift amino acid alteration with premature termination (p.Ile281SerfsX23) within the transmembrane domain. A substitutive mutation found in 1 of the GDLD patients may have resulted from a nonsense mutation (p.Tyr225X) within a region between the thyroglobulin type-1 and transmembrane domains. The transmembrane domain should support the hydrophobic scaffold which may be fundamental to the membrane binding property of this protein. However, and as far as we know, such a domain structure is only a computationally speculated model from the primary amino acid structure of this protein. Therefore, the subcellular localization of both the wild-type and mutated TACSTD2 proteins was experimentally determined in this ...
Corneal dystrophy, lattice type 3A (CDL3A) [MIM:608471]: A form of lattice corneal dystrophy, a class of inherited stromal amyloidoses characterized by pathognomonic branching lattice figures in the cornea. CDL3A is characterized by decreased visual acuity, and the presence of thick, ropy branching lattice lines and accumulations of amyloid deposits in the corneal stroma. Systemic amyloidosis is absent. CDL3A clinically resembles to lattice corneal dystrophy type 3, but differs in that its age of onset is 70 to 90 years. It has an autosomal dominant inheritance pattern. {ECO:0000269,PubMed:15790870, ECO:0000269,PubMed:9497262}. Note=The disease is caused by mutations affecting the gene represented in this entry ...

As with the other endothelial dystrophies, the initial efforts to identify the genetic basis of late-onset FECD consisted of linkage analyses and screening of genes implicated in other corneal endothelial dystrophies. Following the identification of SLC4A11 mutations in individuals with CHED2, Vithana and colleagues screened SLC4A11 in 89 individuals with sporadic and familial FECD, identifying four individuals with presumed pathogenic variants (three missense and one frameshift) [9]. However, as three of the four cases were sporadic, and no affected family members of the fourth individual were available for testing, segregation was not demonstrated for any of the variants [9]. To support their contention that the identified variants were functionally significant, the authors investigated the effects of the 3 heterozygous missense mutations on protein expression and localization. The demonstration of significantly decreased expression of two ...
PURPOSE To investigate whether corneal epithelial cells of individuals with lattice corneal dystrophy (LCD) possess an intrinsic defect. DESIGN Retrospective case-control study. METHODS The medical charts of nine individuals with LCD and those of 14 patients with keratoconus and 11 patients with corneal leukoma (controls), all of whom underwent penetrating keratoplasty (PKP) in one eye at Yamaguchi University Hospital between February 1998 and November 2001, were examined for the time for epithelial resurfacing after surgery. RESULTS The time required for resurfacing of the corneal epithelium after PKP was significantly greater in LCD patients (8.56 +/- 4.95 days, mean +/- SD) than in patients with either keratoconus (1.71 +/- 0.91 days, P = .006) or corneal leukoma (3.00 +/- 1.95 days, P = ...
Fuchs endothelial corneal dystrophy (FECD) MIM#136800 and posterior polymorphous corneal dystrophy (PPCD) MIM#122000 both belong to the corneal endothelial dystrophies in which endothelial dysfunction can lead to corneal oedema. In addition, they both share the common features of endothelial metaplasia and the secretion of an abnormal Descemets membrane as a pathological posterior collagenous layer (PCL) with a small or absent posterior non-banded zone.1,2. The exact cause of both FECD and PPCD is still unknown, although both are thought to be the result of a disorder of neural crest terminal differentiation.3 Mutations in COL8A2, the gene for the α2(VIII) chain of type VIII collagen, have previously been described in patients with both FECD and PPCD,4,5 and type ...

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 ...

Macular corneal dystrophy (MCDC; sometimes also Fehr corneal dystrophy) is a rare pathological condition affecting the stroma of cornea. The first signs are usually noticed in the first decade of life, and progress afterwards, with opacities developing in the cornea. There is also a predisposition to developing painful recurrent corneal erosions. MCDC is inherited in autosomal recessive fashion and is thought to be caused by the lack or abnormal confuguration of keratan sulfate. Most cases of MCD are caused by mutations in CHST6 gene. The condition was first described by Arthur Groenouw in 1890.. Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service at the Duke Eye Center demonstrates the basic techniques behind successful corneal transplantation (penetrating keratoplasty) in a patient with ...
Congenital hereditary endothelial dystrophy (CHED) is an inherited disorder of the corneal endothelium characterised by bilateral non-inflammatory corneal clouding ranging from a diffuse haze to a ground-glass appearance. CHED can be inherited in an autosomal dominant (CHED1) or recessive (CHED2) manner. CHED2 usually presents at birth or early infancy. Bilateral corneal clouding can lead to visual impairment often accompanied by nystagmus in CHED2 patients requiring corneal transplantation.1 Mutations in the solute carrier family 4 member 11 (SLC4A11) gene have been identified in most patients with CHED2. With PCR sequencing of the entire coding and putative promoter regions of SLC4A11, there were, however, some clinically confirmed CHED2 patients with undetected SLC4A11 mutations.2 ...
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 ...
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 ...
BACKGROUND: Early photorefractive keratectomy ablations were of limited diameter and depth to maintain the integrity of the globe and to minimise postoperative haze. This study evaluated the effects of deeper, larger diameter wounds on refractive stability and corneal haze, and investigated the effects of ablation profile on wound healing and visual performance. METHODS: One hundred patients undergoing -3.00D and -6.00D corrections were randomised to receive 5 mm, 6 mm, or multizone treatments. The multizone treatment was 6 mm in diameter, but only the depth of the 5 mm treatment. Outcome was measured by Snellen visual acuity, residual refractive error, objective techniques for haze and halos, pupil diameter, subjective night vision, and requirement for retreatment. RESULTS: Overall, the results of 6 mm treatments were superior to those of 5 mm and multizone treatments: they had a smaller hyperopic shift (p , 0.01), a more predictable (p , 0.001) and stable refractive ...
Purpose: : To investigate functional outcomes and effectiveness of wet field photo therapeutic keratectomy (PTK) for the treatment of superficial central stromal corneal opacities. Methods: : 24 eyes of 12 patients with central superficial stromal opacities treated with 193 nm excimer laser PTK between October 2004 and June 2009 were included. Opacities were caused by macular corneal dystrophy in 24 eyes. After epithelial debridement with 20% isopropyl alcohol; PTK was performed under 0.5% topical proparacaine HCL anesthesia. We applied balanced salt solution (BSS) irrigation to the corneal surface to wet and fill the valleys of prominent superficial corneal lesions, and Wet PTK was performed to the protruded stromal opacities and irregularities. The procedure repeated until the clearance of central lesions. Pre-set laser ...
A band-shaped metal layer useful as a resistance layer and/or a contact layer is pyrolytically deposited onto a cylindrical substrate by surrounding the surface of the substrate with a mixture of a thermally decomposable metal compound and a carrier therefor and substantially simultaneously heating only precise surface areas of the substrate, as by a laser beam, to a temperature slightly above the thermal decomposition temperature of the metal compound and moving the substrate in a rotational and/or axial manner so that a band-shaped metal layer forms only at the heated surface areas of the substrate.
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%).. ...

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 ...

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.

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 ...

Purpose: : Fuchs Corneal Dystrophy (FCD) is an autosomal dominant disease of the corneal endothelium with variable penetrance and expressivity. Recently, Baratz and colleagues reported rs613872, an intronic variation of TCF4 associated with late-onset FCD. The present study was undertaken to examine this association in our cohort of FCD patients and to assess the significance of this finding and to investigate the candidacy of TCF4 in the context of the mapped FCD2 locus. Methods: : We recruited 170 late-onset FCD cases and 180 age-matched controls. Blood samples were collected and genomic DNAs were extracted. A panel of 9 SNPs spanning the entire TCF4 locus was genotyped on both this cohort and on three previously-reported FCD2-linked families. The association of individual SNP with late-onset FCD was evaluated with the Fisher exact test, while the coding exons and exon-intron boundaries of TCF4 were sequenced in 96 affected individuals. ...
Visual system homeobox 1 is a protein that in humans is encoded by the VSX1 gene. The protein encoded by this gene contains a paired-like homeodomain and binds to the core of the locus control region of the red/green visual pigment gene cluster. The encoded protein may regulate expression of the cone opsin genes early in development. Mutations in this gene can cause posterior polymorphous corneal dystrophy (PPCD) and keratoconus. Two transcript variants encoding different isoforms have been found for this gene.

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
PURPOSE: To investigate the functional role that the zinc e-box binding homeobox 1 (ZEB1) gene, which underlies the genetic basis of posterior polymorphous corneal dystrophy 3 (PPCD3), plays in corneal endothelial cell proliferation, apoptosis, migration, and barrier function. METHODS: A human corneal endothelial cell line (HCEnC-21T) was transfected with siRNA targeting ZEB1 mRNA. Cell proliferation, apoptosis, migration, and barrier assays were performed: Cell proliferation was assessed with cell counting using a hemocytometer; cell apoptosis, induced by either ultraviolet C (UVC) radiation or doxorubicin treatment, was quantified by measuring cleaved caspase 3 (cCASP3) protein levels; and cell migration and barrier function were monitored with electric cell-substrate impedance sensing (ECIS ...

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 ...

The long-term goal of this project is to utilize newly available very high-speed OCT technology to guide surgical treatments of corneas with superficial opacities and irregularities. OCT is well known for its exquisite resolution, but until recently it has not had sufficient speed to capture the shape of the cornea because of eye motion during OCT scanning. The development of Fourier-domain OCT (FD-OCT) technology has made the requisite speed possible.. Eyes with superficial opacities (corneal scars and stromal dystrophies) can be treated by phototherapeutic keratectomy (PTK). Currently, many surgeons rely on subjective slit-lamp impression of opacity depth to guide PTK and repeat slit-lamp examinations during surgery to determine if the opacity has been sufficiently reduced. Unpredictable hyperopic shifts can occur after PTK. The aim of this project is to develop methods for imaging the ...
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 ...
Myotonic Dystrophy (DM) a multi-systemic disorder, is the most common adult muscular dystrophy form. Among the pathological manifestations observed in the skeletal musculature include non-muscle defects as insulin resistance. Aberrant regulation has postulated involvement in the disease progression of DM1 specific insulin resistance characteristic of the disorder. RNA binding proteins involved in alternative splicing affect inclusion of spliced exons by binding to sequence specific cis-acting elements in pre-mRNA. The MBNL as well as the CELF class of proteins regulate alternative splicing of pre-mRNA insulin receptor (IR) by working antagonistically as a result of their distinct pre-mRNA binding sites. Of the two isoforms of insulin receptor (IR), the expression of the B isoform is affected to yield the non-muscle, low signaling isoform A. Here attempts are made to demonstrate a relationship between the muscleblind proteins and alternatively spliced insulin receptor by which protein-RNA binding ...
15 eyes of 15 patients with permanent anterior corneal opacities where treated using OCT-guided Transepithelial Phototherapeutic Keratectomy . The etiology of the opacities was of various nature: intractable haze following surface corneal refractive surgery, ocular pemphigoid, ocular trauma, scarring of the cornea following herpetic stromal keratitis. The mean depth of the opacities was 107µm (range from 55 to 199 µm ). The depth of treatment was preoperatively calculated using OCT of the anterior segment. The transepithelial phototherapeutic keratectomies were performed using the Scwhind Amaris 500e excimer laser ...

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 ...

The MidWest EyeCenter recognizes that Advanced Surface Ablation, or ASA, represents a remarkable alternative for patients who would not fit the criteria for traditional refractive surgery at the MidWest EyeCenter in Cincinnati, Ohio.. Patients who have thin or flat corneas, and are too nearsighted for traditional LASIK surgery, can now choose Advanced Surface Ablation as an alternative. Likewise, ASA presents an exciting opportunity for farsighted people whose only alternative previously was glasses or contact lenses.. With ASA, the surface epithelial cells are modified with mild surgical intervention assisted by drops. The corneal surface is then treated with a laser procedure and covered with a bandage contact lens. The surface cells will then reconstruct and create a very strong refractive system. Specific eye drops designed to maximize recovery and outcome are used post-operatively.. For more information regarding Advanced Surface Ablation please contact the MidWest ...

Full Text - Corneal transparency, dependent on the integrity of epithelial cells, is essential for vision. Corneal epithelial damage is one of the most commonly observed ocular conditions and proper wound healing is necessary for corneal transparency. Sirt6, a histone deacetylase, has been shown to regulate many cellular events including aging and inflammation. However, its specific role in corneal epithelial wound healing remains unknown. Here we demonstrated that Sirt6 was expressed in corneal epithelial cells and its expression decreased with age. In an in vivo corneal epithelial wound healing model, Sirt6 deficiency resulted in delayed and incomplete wound healing and was associated excessive inflammation in the corneal stroma and dysfunction of Notch signaling, ...

A limitation to the use of biologic therapies is the risk of significant systemic adverse events. Local administration achieves lower systemic exposure to the drug and therefore is likely associated with lower rates of severe adverse events. The use of infliximab eye drops has been investigated as an alternative modality for local drug delivery. The administration of topical infliximab eye drops reduced corneal opacity, perforation, and eyelid fibrosis in a mouse model of corneal alkali burn,19 and improved tear volume, corneal surface regularity, and goblet cell density in a mouse model of dry eye.20 In rabbit models, the use of topical infliximab prevented corneal neovascularization21 and suppressed subconjunctival wound healing after trabeculectomy.22 On the other hand, cerebrovascular accidents are recognized complications of systemic anti-VEGF therapy23 ...

India has made huge strides from 2007 to 2019 in improving vision care according to Health Ministry with a reduction of the prevalence of blindness by 47% and a reduction in visual impairment by 51.9% . India has additionally reduced the number of blind from 12 million to 4.8 million during that same period. Despite this phenomenal success, cataracts continue to be a challenge.. In those 50 to 90 years of age, cataracts contribute to 66.2% of overall blindness, 80.7% of visual impairment and 70.2% moderate visual impairment. Additional causes of blindness include glaucoma at 5.50% and corneal opacity at 7.40%. Interestingly, 7.2% of blindness in India is due to complications from cataract surgery. Improvements in the quality of cataract surgery training quality should reduce this last number.. Today, there are 116 million Indian citizens aged 60 years or older. 15.42% currently suffer from visual disabilities. By 2050 the number of Indian senior citizens ...
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 ...
An estimated 14 million of the worlds children are blind. A blind child is more likely to live in socioeconomic deprivation, to be more frequently hospitalised during childhood and to die in childhood than a child not living with blindness. This update of a previous review on childhood visual impairment focuses on emerging therapies for children with severe visual disability (severe visual impairment and blindness or SVI/BL).. For children in higher income countries, cerebral visual impairment and optic nerve anomalies remain the most common causes of SVI/BL, while retinopathy of prematurity (ROP) and cataract are now the most common avoidable causes. The constellation of causes of childhood blindness in lower income settings is shifting from infective and nutritional corneal opacities and congenital anomalies to more resemble the patterns seen in higher income settings. Improvements in maternal and neonatal health and investment in and maintenance of national ophthalmic ...
A childs eyes needs regular, equal use to develop normal vision. Poor vision in an eye that did not get enough use during childhood is called amblyopia ("lazy eye"). Treatment during early childhood can usually reverse amblyopia. Treatment after childhood is rarely helpful. A child with amblyopia who does not get treatment will probably have poor vision for the rest of his or her life.. Amblyopia is caused by any condition that affects normal use of the eyes and visual development. In many cases, the conditions associated with amblyopia may be inherited. Children in a family with a history of amblyopia or misaligned eyes should be checked by an Ophthalmologist early in life. There are 3 major causes of amblyopia in children - strabismus (turned eye), unequal focus due to refractive error or cloudiness caused by lens or corneal opacity.. Success in the treatment of amblyopia also depends upon how severe the amblyopia is and how old the child is when treatment ...

Typical clinical signs of congenital glaucoma occurring in the first 2 years of life:. • History of epiphora, photophobia and blepharospasm during the first months of life. • Corneal opacities, tears of the Descemet membrane (Haab striae), an overstretched superior limbal region and large corneal diameters. • In contrast to management in adult glaucoma, several specifications have to be considered in the diagnostic work-up:. • Abnormally increased ocular axial length (in comparison to the normal age-correlated growth curve) is a common feature of congenital glaucoma. However, if onset of glaucoma occurs after 3 years of age the typical stretching of the globe is usually absent. • Despite manifest congenital glaucoma the intraocular pressure may be normal under deep general anesthesia. Several sources of error may confuse intraocular pressure measurements in buphthalmic eyes. • Glaucomatous excavation of the optic disc is usually present, but ...
This forms a population inversion between the two states. Most excimer lasers are of the noble gas halide type, for which the term excimer is strictly speaking a misnomer (since a dimer refers to a molecule of two identical or similar parts): The correct but less commonly used name for such is exciplex laser. The wavelength of an excimer laser depends on the molecules used, and is usually in the ultraviolet: Excimer lasers, such as XeF and KrF, can also be made tunable using a variety of prism and grating intracavity arrangements. Excimer lasers are usually operated with a pulse rate of around 100 Hz and a pulse duration of ~10 ns, although some operate as high as 8 kHz and 200 ns. For electric discharge pump see: Nitrogen laser. The high-power ultraviolet output of excimer lasers makes them useful for surgery (particularly eye surgery), for lithography for semiconductor manufacturing, and for dermatological treatment. However, when in an excited state (induced by an electrical discharge or ...
Diabetic retinopathy is a leading cause of new cases of blindness in people aged 20 to 74 years in the USA.. The total number of people with diabetes is projected to rise from 285 million in 2010 to 439 million in 2030. Diabetic retinopathy is responsible for 1.8 million of the 37 million cases of blindness throughout the world. Diabetic Retinopathy is the 5th leading cause of blindness worldwide behind only cataracts, glaucoma, macular degeneration & corneal opacities.. Diabetic retinopathy (DR) is the leading cause of blindness in people of working age in industrialized countries.. The best predictor of diabetic retinopathy is the duration of the disease.. • After 10 years of diabetes, nearly 70% of patients with type 1 diabetes and 50% of patients with type 2 diabetes have diabetic retinopathy ...

In 2006, ICCVAM forwarded its first recommendations for the use of in vitro test methods for eye injury hazard classification testing to Federal agencies. ICCVAM recommended including the bovine corneal opacity and permeability and the isolated chicken eye test methods in a weight-of-evidence approach to identify products with the potential to cause permanent or severe eye injuries. Substances that test positive in these assays can be classified as ocular corrosives or severe irritants without further testing in animals. Subsequent to acceptance of the ICCVAM recommendations by U.S. federal agencies, the OECD formally adopted guidelines describing the use of the BCOP and ICE test methods, permitting the international use of these test methods to identify substances that may cause permanent or severe eye injuries without the need for animal testing.. ...
We present results of ex vivo imaging of the mouse cornea following photorefractive keratectomy and in vivo imaging in the anterior segment of the rat eye using full-field optical coherence tomography. The instrument is based on the Linnik interferometer, illuminated by a white light source: a tungsten halogen lamp for ex vivo imaging and a fibered Xenon arc lamp for in vivo imaging. En face tomographic images are obtained in real-time without scanning by calculating the difference of two phase-opposed interferometric images recorded by a CCD or CMOS camera. Spatial resolution of ~1 μm in both axial and lateral directions is achieved thanks to the short coherence length of the illumination source and the use of relatively high numerical aperture microscope objectives. A detection sensitivity of up to 90 dB is reached by means of pixel binning and image averaging. Photorefractive keratectomy was performed on mice and the excised eyes were examined under immersion 21 days after surgery. Rats were ...

Morquio syndrome is an autosomal recessive mucopolysaccharidosis characterized by short trunk dwarfism, fine corneal opacities, skeletal changes, and normal intelligence. Morquio syndromes A (MPS4A; {253000}) and B (MPS4B; {253010}) are caused by mutations in the N-acetylglucosamine-6-sulfate sulfatase (GALNS; {612222}) and beta-galactosidase (GLB1; {611458}) genes, respectively. MPS4A and MPS4B are characterized biochemically by increased urinary excretion of keratan sulfate ({1:Beck et al., 1986}). There is some evidence of an additional form of Morquio syndrome, referred to here as type C, in which urinary excretion of keratan sulfate is absent. However, {5:McKusick (1972)} suggested that the nonkeratosulfate- excreting Morquio syndrome may be allelic to other forms of Morquio syndrome ...

A cation channel disorder, characterized by severe neurological and ophthalmologic abnormalities, ML4 usually presents during the first year of life with mental retardation, corneal opacities, and delayed motor milestones. Children with ML4 typically reach a maximum developmental age of 15 months.
Introduction. Fabry disease is a rare genetic lysosomal storage disorder of glycosphingolipids with X-linked transmission and an estimated incidence of 1:40,000-1:117,000 live male births.1 Partial or complete deficiency of the enzyme alpha-galactosidase A (a-Gal A) results in altered metabolism and progressive lysosomal accumulation of the substrate (mostly globotriaosylceramide, Gb3).2 The responsible gene is located on the long arm of the chromosome X (Xq22). More than 600 mutations have been identified with variable phenotypical expression.3. Clinically we distinguish the classical form and two variants, cardiac and renal. In the classical form clinical manifestations appear during childhood or early adolescence including acroparesthesias, angiokeratomas and corneal opacities.4 Progressive accumulation of Gb3 in the kidneys, heart and central nervous system lead to renal failure, hypertrophic cardiomyopathy and cerebral vascular accidents limiting life expectancy. The ...

Inflammatory eye disease (uveitis) can develop as a complication in children who have juvenile idiopathic arthritis (JIA). Children and adults who have JIA can develop cataracts, glaucoma, corneal degeneration (band keratopathy), or vision loss.. The incidence of eye disease is 2 to 34 out of 100 children who have JIA.footnote 1 It is most common in oligoarticular and RF-negative polyarticular forms of the disease. Eye disease associated with JIA often has no symptoms, although blurred vision may be an early sign. To prevent eye problems from progressing to the point that vision loss occurs, regular eye examinations by an ophthalmologist are very important for children who have JIA. Eye disease develops in about 30 out of 100 children who have oligoarticular JIA, particularly children who have a positive antinuclear antibody (ANA) test result.footnote 2. Early detection and treatment of inflammatory eye disease gives a child the best chance of a good outcome. Discuss the ...
This is EM Cases Journal Jam Podcast 6 - Outpatient Topical Anesthetics for Corneal Abrasions. Ive been told countless times by ophthalmologists and other colleagues NEVER to prescribe topical anesthetics for corneal abrasion patients, with the reason being largely theoretical - that tetracaine and the like will inhibit re-epithelialization and therefore delay epithelial healing as well as decrease corneal sensation, resulting in corneal ulcers. With prolonged use of outpatient topical anesthetics for corneal abrasions, corneal opacification could develop leading to decreased vision. Now this might be true for the tetracaine abuser who pours the stuff in their eye for weeks on end, but when we look at the literature for toxic effects of using topical anesthetics in the short term, there is no evidence for ...

It is widely accepted that women carry an increased burden of trachomatous trichiasis compared with men, but there is no systematic review of the available prevalence surveys in the peer-reviewed literature. A literature search was conducted to identify population-based trachoma prevalence surveys utilising the WHO simplified grading system that included data for trichiasis.
Cited in: See also: J Urol 1991 Sep;146(3):840-2 PMID: 1875507, UI: 91341922 Nonhair-bearing skin should be used when grafting is necessary during urethroplasty for stricture or hypospadias repair. Occasionally, this is not possible or hair-bearing skin is used inadvertently. Traditionally, electrocoagulation has been the method used for epilation when intraluminal hair has become a problem, such as interfering with flow, as a focus for recurrent urinary tract infection or acting as a nidus for calculus formation. Electrocautery also is performed during grafting in an attempt to prevent the growth of hair when hair-bearing skin is used. Unfortunately, due to lack of penetration the hair follicles are not destroyed and the epilating procedure fails or is only partially successful. The neodymium:YAG surgical laser can photocoagulate tissue to a depth up to 5.0 mm, and thus, has the ability to destroy hair follicles. We report 4 cases presenting with clinical problems directly related to ...
I just had PRK done on both of my eyes this past Thursday and thought I would share my perspectives. For those who arent familiar, PRK stands for Photorefractive Keratectomy. A similar procedure called Laser-Assisted Sub-Epithelial Keratectomy (LASEK) differs from PRK in whether the epithelium is preserved. The epithelium, is a soft, rapidly regrowing, outermost layer of the cornea in contact with the air. The epithelium can completely replace itself within a few days. Both PRK and LASEK permanently change the shape of the anterior (outermost) central cornea using an excimer laser to ablate (burn off) a small amount of tissue from the corneal stroma at the front of the eye, just under the corneal epithelium. In both PRK and LASEK, the epithelium is softened (with alcohol) and detached from the eye and removed prior to the ablation. In PRK, the epithelium is discarded. In LASEK, the epithelium is preserved and replaced after the laser ...

  • A second goal is to develop a more sophisticated OCT guidance system incorporating OCT topography of anterior and posterior corneal surfaces and to develop a mathematical model that relates epithelial thickness variation to corneal mean curvature. (clinicaltrials.gov)
  • Preoperative measurements from the OCT are used to assist the calculation in deciding the laser depth settings for removal of anterior corneal opacities and defects in the phototherapeutic PTK procedure. (clinicaltrials.gov)
  • The purpose of this study is to determine whether OCT-guided settings for the lasers used for removal of corneal scars and other partial-thickness corneal defects result in improved vision in patients receiving these procedures. (clinicaltrials.gov)
  • Deep ulcers need support in the form of corneal or conjunctival grafts. (vin.com)
  • Conjunctivochalasis (CCH) usually tests positive for corneal and conjunctival staining and a rapid TBUT, but in mild-to-moderate cases, osmolarity is normal while MMP-9 testing can be elevated. (reviewofoptometry.com)
  • The treatment can be as simple as some antibiotic eye drops to treat the ulcer, or can require surgery to remove the abnormal corneal cell layers. (shilohshepherds.info)
  • Keratomalacia, or the so-called " melting corneal ulcer, " is common in clinical practice. (vin.com)
  • As clinical manifestations widely vary with the different entities, corneal dystrophies should be suspected when corneal transparency is lost or corneal opacities occur spontaneously, particularly in both corneas, and especially in the presence of a positive family history or in the offspring of consanguineous parents. (wikipedia.org)
  • Pre- and up to 3 weeks post-induction, corneas were noninvasively examined by laser-scanning in vivo corneal confocal microscopy (IVCM) using only endogenous contrast. (diva-portal.org)
  • Slit lamp examination revealed diffusely hazy corneas with opacities bilaterally. (harvard.edu)
  • Corneal diseases and disorders do not always produce noticeable symptoms. (kocheye.com)
  • Corneal conditions can cause a combination of these symptoms or may not cause any at all. (kocheye.com)
  • At Koch Eye Associates, we have an experienced team of ophthalmologists who are highly trained in diagnosing and treating corneal diseases and disorders. (kocheye.com)
  • Fortunately, when the deposits recur, they tend to be superficial, and amenable to treatment with excimer laser PTK. (medscape.com)
  • Melatonin reduces endoplasmic reticulum stress and corneal dystrophy-associated TGFBIp through activation of endoplasmic reticulum-associated protein degradation. (medscape.com)
  • We examined the role of chromatin markers such as histone H3 lysine methylation (H3Kme) in TGFβ1-induced TGFBIp and ECM gene expression in normal and GCD2-derived human corneal fibroblasts. (biomedcentral.com)
  • TGFβ1 increased the expression of TGFBIp and the ECM-associated genes connective tissue growth factor, collagen-α2[Ι], and plasminogen activator inhibitor-1 in normal corneal fibroblasts. (biomedcentral.com)
  • Taken together, the results show the functional role of H3K4me in TGFβ1-mediated TGFBIp and ECM gene expression in corneal fibroblasts. (biomedcentral.com)
  • The molecular mechanisms and cellular role of TGFBIp in corneal dystrophy pathogenesis are poorly understood. (biomedcentral.com)
