Diseases of the cornea.
Medicines whose effectiveness is unproven and whose ingredients are often secret.
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
Inflammation of the cornea.
A superficial, epithelial Herpesvirus hominis infection of the cornea, characterized by the presence of small vesicles which may break down and coalesce to form dendritic ulcers (KERATITIS, DENDRITIC). (Dictionary of Visual Science, 3d ed)
A form of herpetic keratitis characterized by the formation of small vesicles which break down and coalesce to form recurring dendritic ulcers, characteristically irregular, linear, branching, and ending in knoblike extremities. (Dictionary of Visual Science, 3d ed)
Loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.
Infections in the inner or external eye caused by microorganisms belonging to several families of bacteria. Some of the more common genera found are Haemophilus, Neisseria, Staphylococcus, Streptococcus, and Chlamydia.
Stratified squamous epithelium that covers the outer surface of the CORNEA. It is smooth and contains many free nerve endings.
Partial or total replacement of the CORNEA from one human or animal to another.
A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (From Dorland, 27th ed)
The lamellated connective tissue constituting the thickest layer of the cornea between the Bowman and Descemet membranes.
Bilateral hereditary disorders of the cornea, usually autosomal dominant, which may be present at birth but more frequently develop during adolescence and progress slowly throughout life. Central macular dystrophy is transmitted as an autosomal recessive defect.
Partial or total replacement of all layers of a central portion of the cornea.
The fluid secreted by the lacrimal glands. This fluid moistens the CONJUNCTIVA and CORNEA.

Infection of the cornea by an ameboid protozoan which may cause corneal ulceration leading to blindness.
The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.
New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999)
Single layer of large flattened cells covering the surface of the cornea.
The type species of SIMPLEXVIRUS causing most forms of non-genital herpes simplex in humans. Primary infection occurs mainly in infants and young children and then the virus becomes latent in the dorsal root ganglion. It then is periodically reactivated throughout life causing mostly benign conditions.
Infections with bacteria of the genus PSEUDOMONAS.
The mucous membrane that covers the posterior surface of the eyelids and the anterior pericorneal surface of the eyeball.
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
The species Oryctolagus cuniculus, in the family Leporidae, order LAGOMORPHA. Rabbits are born in burrows, furless, and with eyes and ears closed. In contrast with HARES, rabbits have 22 chromosome pairs.
A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)
VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.
Disorder caused by loss of endothelium of the central cornea. It is characterized by hyaline endothelial outgrowths on Descemet's membrane, epithelial blisters, reduced vision, and pain.
Structured vocabularies describing concepts from the fields of biology and relationships between concepts.

Purulent infections of the conjunctiva by several species of gram-negative, gram-positive, or acid-fast organisms. Some of the more commonly found genera causing conjunctival infections are Haemophilus, Streptococcus, Neisseria, and Chlamydia.
Corneal and conjunctival dryness due to deficient tear production, predominantly in menopausal and post-menopausal women. Filamentary keratitis or erosion of the conjunctival and corneal epithelium may be caused by these disorders. Sensation of the presence of a foreign body in the eye and burning of the eyes may occur.
The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.
The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
Measurement of the thickness of the CORNEA.

Causes of corneal graft failure in India. (1/900)

The success of corneal grafting in visual rehabilitation of the corneal blind in India depends on survival of the grafts. Understanding the causes of graft failure may help reduce the risk of failure. We studied these causes in a series of 638 graft failures at our institution. Multivariate logistic regression analysis was used to evaluate the association of particular causes of graft failure with indications for grafting, socioeconomic status, age, sex, host corneal vascularization, donor corneal quality, and experience of surgeon. The major causes of graft failure were allograft rejection (29.2%), increased intraocular pressure (16.9%), infection excluding endophthalmitis (15.4%), and surface problems (12.7%). The odds of infection causing graft failure were significantly higher in patients of lower socioeconomic status (odds ratio 2.45, 95% CI 1.45-4.15). Surface problems as a cause of graft failure was significantly associated with grafts done for corneal scarring or for regrafts (odds ratio 3.36, 95% CI 1.80-6.30). Increased intraocular pressure as a cause of graft failure had significant association with grafts done for aphakic or pseudophakic bullous keratopathy, congenital conditions or glaucoma, or regrafts (odds ratio 2.19, 95% CI 1.25-3.84). Corneal dystrophy was the indication for grafting in 12 of the 13 cases of graft failure due to recurrence of host disease. Surface problems, increased intraocular pressure, and infection are modifiable risk factors that are more likely to cause graft failure in certain categories of patients in India. Knowledge about these associations can be helpful in looking for and aggressively treating these modifiable risk factors in the at-risk categories of corneal graft patients. This can possibly reduce the chance of graft failure.  (+info)

Excimer laser ophthalmic surgery: evaluation of a new technology. (2/900)

The aim of this article is to provide information and an overview of the potential risks and benefits of excimer laser surgery, a new and promising technique in ophthalmic surgery. Although this review concentrates on the use of the laser for refractive purposes, novel therapeutic techniques are also discussed. It is hoped that this will enable general practitioners, optometrists and physicians to provide appropriate advice and counselling for patients.  (+info)

TNF-alpha production in the cornea in response to Pseudomonas aeruginosa challenge. (3/900)

Pseudomonas aeruginosa can cause ulcerative bacterial keratitis or contact lens-induced acute red eye (CLARE) in humans. The present study used a mouse model of ocular infection and inflammation to examine the relationship between TNF-alpha and inflammation in the cornea in response to challenge with either a strain of P. aeruginosa causing keratitis or a CLARE strain. Constitutive TNF-alpha mRNA was detected in the epithelium, mainly towards the periphery. After infection with the keratitis-inducing strain (6294), TNF-alpha expression was elevated four-fold by 24 h post-challenge. No detectable induction of TNF-alpha mRNA was seen with CLARE strain (Paer1) challenge at any time point. The TNF-alpha protein production detected by ELISA showed a corresponding pattern to the mRNA expression, which also correlated with pathological changes. These results suggest that invasive strains of P. aeruginosa create greater pathological changes as a result of elevated TNF-alpha production, which contributes to inflammation during keratitis in vivo.  (+info)

Matrix metalloproteinases in epithelia from human recurrent corneal erosion. (4/900)

PURPOSE: To assay for the presence of matrix metalloproteinases (MMPs) in human corneal epithelium affected by recurrent erosion compared with that in normal corneal epithelium. METHODS: Corneal epithelial debridement samples were obtained from 13 patients with recurrent epithelial erosion. For control specimens, epithelia were obtained from healthy patients undergoing photorefractive keratectomy. Zymography was performed on all samples to identify MMPs. Immunolocalization of MMP-2, laminin, and collagen type VII was determined in two samples with human recurrent epithelial erosion and compared with that in control epithelium. RESULTS: Twelve of 13 erosion samples showed MMP-2 enzymatic activity; one of the 12 also showed MMP-9 activity. Only one erosion sample showed no MMP enzymatic activity. All normal control specimens were negative for MMP. Immunohistochemical analysis of two recurrent erosion samples showed MMP-2 presence in basal cells, whereas, in normal epithelium it was not detected. One sample with epithelial erosion showed laminin localization in basal epithelial cells and basal lamina. Type VII collagen localized in basal epithelial cells only in this sample. A second erosion sample showed localization of laminin and type VII collagen in basal epithelial cells only. Normal corneal epithelium showed presence of laminin and type VII collagen in basal epithelium and basal lamina. CONCLUSIONS: Matrix metalloproteinase-2 expression is upregulated in human epithelia affected by recurrent erosion compared with that in normal control samples. Immunolocalization studies suggest that this enzyme is concentrated in basal epithelial cells where it may play an important role in degradation of the epithelial anchoring system and the recurrent epithelial slippage and erosion observed in these patients.  (+info)

Ocular ochronosis in alkaptonuria patients carrying mutations in the homogentisate 1,2-dioxygenase gene. (5/900)

AIMS: To assess the involvement of the recently identified human homogentisate 1,2-dioxygenase gene (HGO) in alkaptonuria (AKU) in two unrelated patients with ochronosis of the conjunctiva, sclera, and cornea. METHODS: A mutation screen of the entire coding region of the HGO gene was performed using single stranded conformational analysis after polymerase chain reaction with oligonucleotide primers flanking all 14 exons of the HGO gene. Fragments showing aberrant mobility were directly sequenced. RESULTS: Two homozygous missense mutations, L25P and M368V, were identified, each of which leads to the replacement of a highly conserved amino acid in the HGO protein. CONCLUSIONS: The authors describe a novel mutation, L25P, in the German population and bring to 18 the total number of known HGO mutations.  (+info)

Confocal microscopy in the iridocorneal endothelial syndrome. (6/900)

AIMS: To report the appearances of iridocorneal endothelial (ICE) syndrome from real time, white light confocal microscopy. METHODS: Three consecutive patients, each with ICE syndrome, were examined prospectively. Corneal specular and confocal microscopic examinations were performed in all three patients. In the first patient, a penetrating keratoplasty was performed and the cornea was examined by light and scanning electron microscopy. No surgery was performed in the remaining two patients. RESULTS: In the first patient corneal oedema prevented endothelial specular microscopy. Confocal microscopy performed before penetrating keratoplasty successfully revealed abnormal epithelial-like endothelial cells. Histological examinations of the cornea following penetrating keratoplasty revealed the presence of multilayered endothelial cells with epithelial features (microvilli). In the remaining two patients, specular microscopy showed the presence of ICE cells with typical dark/light reversal. Confocal microscopy demonstrated groups of endothelial cells with epitheloid appearances. In all three patients, the contralateral endothelial appearance was normal by specular and confocal microscopy, except for moderate endothelial polymegathism in one patient. Epithelial-like endothelial cells were characterised by prominent nuclei on confocal microscopy. CONCLUSIONS: The application of confocal microscopy indicates that the ICE syndrome is characterised by epitheloid changes in the endothelium. Confocal microscopy may be used to diagnose the ICE syndrome by demonstrating epithelial-like endothelial cells with hyperreflective nuclei. This technique is especially of value in cases of corneal oedema, since specular microscopy may fail to image the endothelium in such cases.  (+info)

Treatment of severe ocular-surface disorders with corneal epithelial stem-cell transplantation. (7/900)

BACKGROUND: Conditions that destroy the limbal area of the peripheral cornea, such as the Stevens-Johnson syndrome, ocular pemphigoid, and chemical and thermal injuries, can deplete stem cells of the corneal epithelium. The result is scarring and opacification of the normally clear cornea. Standard corneal transplantation cannot treat this form of functional blindness. METHODS: We performed and evaluated 70 transplantations of corneal epithelial stem cells from cadaveric eyes into 43 eyes of 39 patients with severe ocular-surface disorders and limbal dysfunction. Medical treatment had failed in all patients. The patients had a mean preoperative visual acuity of 0.004 (only being able to count the number of fingers presented by the examiner) in the affected eyes, which satisfies the criteria for legal blindness in most countries. In 28 eyes, we also performed standard corneal transplantation. Stem-cell transplantations were performed as many as four times on 1 eye if the initial results were not satisfactory; 19 eyes had multiple transplantations. Patients were followed for at least one year after transplantation. RESULTS: A mean of 1163 days after stem-cell transplantation, 22 of the 43 eyes (51 percent) had corneal epithelialization; of the 22 eyes, 7 eyes had corneal stromal edema and 15 eyes had clear corneas. Mean visual acuity improved from 0.004 to 0.02 (vision sufficient to distinguish the largest symbol on the visual-acuity chart from a distance of 1 m) (P<0.001). The 15 eyes in which the cornea remained clear had a final mean visual acuity of 0.11 (the ability to distinguish the largest symbol from a distance of 5 m). Complications of the first transplantation included persistent defects in the corneal epithelium in 26 eyes, ocular hypertension in 16 eyes, and rejection of the corneal graft in 13 of 28 eyes. The epithelial defects eventually healed in all but two of the eyes. CONCLUSIONS: Transplantation of corneal epithelial stem cells can restore useful vision in some patients with severe ocular-surface disorders.  (+info)

The p53 tumor suppressor gene of the marsupial Monodelphis domestica: cloning of exons 4-11 and mutations in exons 5-8 in ultraviolet radiation-induced corneal sarcomas. (8/900)

Inactivating p53 mutations are found in many ultraviolet radiation (UVR)-induced skin tumors. We examined 12 UVR-induced corneal tumors of the marsupial Monodelphis domestica for mutations in exons 5-8 of p53 and compared their mutational spectrum with that of UVR-induced skin tumors of other species. First we cloned and characterized a cDNA extending from the middle of exon 4 through exon 11 of the Monodelphis p53 gene. Based on the sequence information obtained, primers were designed to amplify introns 4-9 of the gene; intron primers to amplify individually exons 5-8 were subsequently developed. 'Cold' single strand conformational polymorphism analysis followed by reamplification of DNA with altered mobility and cycle sequencing revealed single p53 mutations in four of 12 tumors (33%), including one mutation in exon 5, two identical mutations in exon 7 and one mutation in exon 8. All mutations were at dipyrimidine sites and occurred on the non-transcribed strand. Three of the four were hallmark UVR-induced C-->T alterations. Three of the mutations were found at sites corresponding to human codons 248 and 273, which are mutational hotspots in human and murine UVR-induced squamous cell carcinomas. Our findings suggest that UVR-induced corneal sarcomas in Monodelphis will be valuable in studying mechanisms of p53 mutation in UVR-induced tumors.  (+info)

Recurrent Erosion Syndrome (RES) is a spontaneous breakdown of the corneal epithelium (the outermost layer of the cornea). This occurs because the outer layer is weakly attached to the underlying membrane. The most common cause of Recurrent Erosion Syndrome is an initial minor corneal injury or abrasion, such as that caused by a fingernail. Other disease processes that can elicit Recurrent Erosion Syndrome include dystrophies, infections, diabetes, and dry eyes.. ...
This study investigated DE-105 in patients with persistent corneal epithelial defect. The primary endpoint was restoration of corneal epithelial defect assessed
This study also suggests that α-toxin is active in producing ocular changes in eyes infected with strain Newman. All the Newman strains, except the one deficient in α-toxin, produced corneal epithelial erosions that were readily visible on gross examination and in histologic sections of corneas. Corneal erosions produced by the γ-toxin-deficient Newman strain, but not the α-toxin-deficient mutant, are evidence for a role for α-toxin in corneal epithelial erosion produced by strain Newman. Also, supporting a role for α-toxin in the corneal virulence of strain Newman was the protection against corneal damage, especially epithelial erosion, afforded by either active or passive immunization to α-toxin. The epithelial erosions caused by Newman strains developed more slowly and were smaller throughout the 25 hours of infection than those caused by strain 8325-4, a strain in which α-toxin is the key hemolytic toxin. This difference in the rate of erosion formation correlates with the relatively ...

Recurrent corneal erosions are a common complication of superficial corneal wounds. They most commonly arise following a trauma, in association with various corneal dystrophies, or are idiopathic.. The main aim of this thesis was to investigate two hereditary corneal diseases with recurrent erosions in order to find out if they had been described before, and more specifically to describe the clinical picture and the morphological changes, differentiate them from other known autosomal dominant corneal dystrophies with a clinical resemblance, and to exclude genetic linkage to known corneal dystrophies with autosomal-dominant inheritance and a clinical resemblance.. The thesis is based on two families of subjects belonging to different phenotypes. The subjects from Småland (Dystrophia Smolandiensis) belonged to a six-generation family, which included 171 individuals of whom 44 were affected individuals, and the family from Hälsingland (Dystrophia Helsinglandica) included sevengenerations of 342 ...
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%).. ...
There are several reports on the treatment of recalcitrant recurrent corneal erosion syndrome by excimer laser PTK.23-31 The reported rate of success, regarding alleviation of symptoms and prevention of recurrence of epithelial erosion, ranges between 74.4% and 100%.23-31 Dauschet al 23 reported a success rate of 74.4% in 74 eyes treated by PTK. OBrart et al 27reported that four out of 17 eyes (23.5%) experienced recurrent episodes 3-6 months after PTK and two have subsequently been retreated, one of whom has been symptom free for 12 months following retreatment. Postoperative BVA was unaltered in nine eyes and improved by at least one Snellen line in eight eyes. Both Forster et al 31 and Algawi et al 24 reported that none of their treated patients had experienced recurrence of corneal erosion. However, Algawi et al24 reported that two of 14 patients still complained of transient, recurrent foreign body sensation following PTK, although none of their patients developed recurrence of 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 removal can be considered. Usually, vision improves following the removal of calcium from the cornea.. CORNEAL DELLEN Dellen ...

The treatment for recurrent corneal erosion is very similar to that for corneal abrasion. Patching is often very helpful, usually after the instillation of an antibiotic ointment. The doctor may teach you how to open your eye carefully and remind you never to rub the eye. If there is an underlying corneal disease requiring treatment, that too will be addressed. Often, you will be given a salt-like drop for day use and salt-like ointment for nighttime use. The salt pulls fluid out of the corneal epithelium, allowing it to lay down tighter to the underlying basement membrane and, hence, heal better. Map-dot fingerprint dystrophy, which most patients dont know they have, usually resolves over several years on its own without treatment. Some patients may also be taught how to apply a tight patch that restricts eye movement at night and upon waking so there is less likelihood of recurrence. If these rather simple procedures are not successful, the eye care professional may re-scrape the area to ...

Title:Corneal Changes in Diabetes Mellitus. VOLUME: 8 ISSUE: 4. Author(s):Guzel Bikbova, Toshiyuki Oshitari, Ayako Tawada and Shuichi Yamamoto. Affiliation:Department of Ophthalmology and Visual Science, Chiba University Graduate School of Medicine, Inohana 1-8-1, Chuo-ku, Chiba 260-8670, Chiba, Japan.. Keywords:Advanced glycation end-products, corneal wound healing, diabetes mellitus, endothelial cell dysfunction, epithelial defect, growth factors, neurotrophic keratopathy, vitrectomy, keratopathy, diabetic polyneuropathy. Abstract:Diabetes mellitus is a major disease worldwide, and the prevalence of diabetes has risen significantly in the past several decades. Although one of the major complications of diabetic eyes is diabetic retinopathy (DR), corneal diseases can not only develop in diabetic patients but are also difficult to manage. Diabetic neurotrophic keratopathy is a component of diabetic polyneuropathy and is recognized to be the cause of the morbidity of the cornea in diabetic ...
To date, GWAS in humans have identified 27 CCT-associated loci,13,16,23-25 and QTL analysis in mice has identified 6 CCT-associated loci. Some of the genes identified in GWAS were independently identified as CCT regulators because of their association with rare connective tissue disorders (i.e., brittle cornea syndrome and osteogenesis imperfecta).11,12,15 The genes identified by GWAS show an enrichment of pathways involving collagen and extracellular matrix (ECM), which might be expected since the cornea is composed largely of an ECM-rich stroma. Other CCT-influencing genes (e.g., Twist2, Bnc1, Bcl-2, and Bax) have been identified through studies that used candidate-driven approaches.44-46 A comparison of the syntenic regions of Cctq4 indicated that this locus overlaps partially with Tiparp, a locus previously reported to be associated with CCT in humans based on a meta-analysis by Lu et al.16 However, Tiparp is unlikely to be the gene underlying the association between Cctq4 and CCT because it ...

The corneal epithelial cells are the fastest reproducing cells in the human body, but it will take time for them to cover the area, thicken, and smooth. You will undoubtedly have some corneal edema (inflammation) from the insult, which will cause fluctuations in your refractive error and likely an uneven healing pattern until things settle down. Your poor vision will wax and wane and change over the next 2-3 weeks. You will likely not get the really good vision you want until 4-6 weeks or even a bit longer. You will undoubtedly have functional vision within a week, but you wont be threading any needles with that eye ...
Diabetic corneal neuropathy: clinical perspectives Guzel Bikbova,1,2 Toshiyuki Oshitari,1 Takayuki Baba,1 Mukharram Bikbov,2 Shuichi Yamamoto1 1Department of Ophthalmology and Visual Science, Chiba University Graduate School of Medicine, Chiba, Japan; 2Cornea and Refractive Surgery Department, Ufa Eye Research Institute, Ufa, Russia Abstract: Diabetic keratopathy is characterized by impaired innervation of the cornea that leads to decreased sensitivity, with resultant difficulties with epithelial wound healing. These difficulties in wound healing put patients at risk for ocular complications such as surface irregularities, corneal infections, and stromal opacification. Pathological changes in corneal innervations in diabetic patients are an important early indicator of diabetic neuropathy. The decrease in corneal sensitivity is strongly correlated with the duration of diabetes as well as the severity of the neuropathy.

But it closed Yesterday, and that was my worse vision day thus far. It was so so blurry it made my head swim. However I still have some DLK inflammation that has persisted around the edge of my flap and he has increased my steroid drops and oral steroids a little. But other that that my vision isnt as bad today. But it is still a blurry mess overall ...

This is lipid deposition with associated blood vessels probably after a corneal ulcer. Wed call this a lipid keratopathy, though Ive never seen one in a cat before and cant find a report of it in the literature. Not enough money, or a calm enough cat, to take a blood sample for lipid analysis Im afraid, but as the cat is happy no treatment is needed. If it were maybe the driver of this truck I passed on the way home from the consultation would be able to help! ...

Etiology: Band keratopathy derives its name from the distinctive appearance of calcium deposition in a band across the central cornea. Band keratopathy can occur from a variety of causes, both systemic and local. Bank keratopathy is associated with chronic corneal edema (perhaps the most common treatable cause accounting for over 1/4 of cases in one series), phthisis bulbi, chronic iridocyclitis, severe glaucoma, hyperparathyroidism, vitamin D excess, sarcoidosis or renal disease. The latter 4 are related to abnormal calcium metabolism. Severe dry eye may also precede band keratopathy. Herpes keratitis may predispose to band keratopathy. The use of phosphate salts in steroid preparations may precipitate calcium in patients with epithelial defects ...

Y1 - 1996/2/15. N2 - Purpose: The immunohistochemical staining characteristics of corneal endothelium was studied to clarify the usefulness of these stains in the pathologic diagnosis of epithelial downgrowth. Methods: Tissue sections of formalin-fixed, paraffin-embedded corneal specimens (keratoconus, pseudophakic bullous keratopathy, epithelial downgrowth, failed corneal grafts with retrocorneal fibrous membranes, and postmortem control corneas) were immunostained with a panel of corneal epithelial and endothelial markers (EMA, KAE 1/3, CAM5.2, Factor VIII, CD-34, CD-31) and with Vimentin using the Strept-Avidin technique (Dako). Results: Corneal endothelium is immunonegative for endothelial cell markers (CD-34,CD-31, and Factor VIII) and displays immunopositivity for epithelial markers (KAE 1/3, CAM 5.2). ...
Case Report DOI:10.14744/bej.2019.79553 Beyoglu Eye J 2019; 4(2): 126-129 Manual Intracorneal Silicone Oil Insertion for Symptomatic Treatment of Bullous Keratopathy in a Patient with Corneal Scarring Selim Genc, Semih Cakmak, Yusuf Yildirim Department of Ophthalmology, University of Health Sciences, Beyoglu Eye Training and Research Hospital, Istanbul, Turkey Abstract Bullous keratopathy is a result of endothelial loss and the failure of the remaining corneal epithelium to pump leaking water molecules away from the corneal tissue, causing overhydration. In eyes with good visual potential, keratoplasty is the primary treatment. There are also several other approaches to provide temporary improvement until a permanent solution with keratoplasty can be achieved. These alternatives include hypertonic topical sodium chloride (5%) drops, bandage contact lenses, anterior stromal puncture, phototherapeutic keratectomy, amniotic membrane transplantation, conjunctival flaps, and collagen crosslinking. ...
TY - JOUR. T1 - Autologous cultivated limbal stem cell transplantation after failed previous limbal graft. AU - Knutsson, KA. AU - Matuska, S. AU - Rama, P. PY - 2017. Y1 - 2017. N2 - Purpose: To describe a case of unilateral limbal stem cell deficiency (LSCD) with previously failed autologous graft, resolved by ocular surface reconstruction using cultured autologous limbal stem cells from the contralateral eye. Case report: A 35-year-old patient presented to our clinic with LSCD due to a unilateral alkali burn. The patient had received a previous limbal graft from the contralateral eye that had failed to impede corneal conjunctivalization. We decided to repeat limbal stem cell transplantation using an ex vivo cultivation procedure to reduce the risk of tissue harvesting on the healthy fellow eye. A small limbal biopsy (1.5 × 1.5 mm) near the previously excised limbus was performed. Stem cells were then isolated and cultured on fibrin and a 3T3 feeder cell layer using a standard protocol. Four ...
PURPOSE: We report our experience with the use of maternally derived serum eye drops as adjunctive treatment in the management of pediatric persistent corneal epithelial defects. METHODS: Five eyes of 4 patients were identified in a retrospective review of pediatric patients with persistent corneal epithelial defects who received maternal serum drops. Diagnoses associated with the defects comprised pontine tegmental cap dysplasia with bilateral cranial nerve V1, V2, V3, and VII palsies; pontine tegmental cap dysplasia with left cranial nerve V1, VII, and VIII palsies; traumatic left cranial nerve II, V1, V2, and VI palsies due to a basilar skull fracture; and Stevens-Johnson syndrome with ocular involvement ...
Abstract Objective: A population of stem cells (SCs) is responsible for maintenance and repair of the ocular surface. These stem cells can become deficient as a result of various diseases affecting the ocular surface. Depending on the extent of damage, the clinical features can vary from mild discomfort to substantial pain and/or blindness. The growing field of tissue engineering and advances in stem cell research offer promising new alternatives for these disorders. This student thesis will provide an overview of the human ocular surface (cornea, limbus, and conjunctiva), ocular surface stem cell deficiency, and treatment possibilities. Methods: This student thesis is based on a number of review articles and original articles on PubMed using the search words limbal, limbal stem cell deficiency, conjunctival and/or ocular surface reconstruction. Only papers written in English were considered. Findings: There are different possible methods for treating ocular surface stem cell deficiency by ...
Aniridia is a congenital autosomal dominant, bilateral, panocular condition, caused by haploinsufficiency of the Pax6 transcription factor. Aniridia-related keratopathy (ARK) significantly affects vision and quality of life in these patients. ARK is a chronic progressive keratopathy comprising limbal stem cell deficiency associated with impaired epithelial cell adhesion, corneal conjunctivalization, epithelial erosions and corneal vascular pannus that typically only appear after childhood.. The aims were i) to evaluate the structural changes and ii) cell signaling pathways, including the Notch1, Sonic Hedgehog (SHH), mTOR and Wnt/beta-catenin cell signaling pathways in naïve and surgically treated corneas of aniridia cases with advanced ARK and comparing with normal human adult and fetal corneas and iii) to develop a corneal cell culture model of aniridia.. Naïve ARK corneas removed at the time of the first transplantation and ARK corneal buttons removed after a failed keratolimbal allograft ...
Band keratopathy is characterized by the appearance of a band across the central cornea, formed by the precipitation of calcium salts on the corneal surface (directly under the epithelium). This form of corneal degeneration can result from a variety of causes, either systemic or local, with visual acuity decreasing in proportion to the densit...
Corneal transplant surgery is the most commonly performed of all transplant operations, with approximately 45,000 corneal transplant procedures being performed in the Unites States each year. The indications for corneal transplant surgery have changed through the years. Pseudophakic bullous keratopathy and aphakic bullous keratopathy (corneal edema secondary to cataract surgery) accounted for 80% of corneal transplants in the 1980s. However, with the improvement of cataract surgery techniques, conditions such as Fuchs Dystrophy, Keratoconus, and other corneal dystrophies are now more commonly transplanted.. In 1933, corneal transplants were performed using two razor blades to make a square graft. Patients were hospitalized for two weeks with sand bags on either side of their head to prevent undesirable movement and possible leakage from the wound sites. Since then, there have been major advances in surgical technique including the introduction of the operating microscope (1970s) and better ...

Bullous keratopathy is a condition where corneal endothelial cells, which do not normally proliferate in vivo, are extensively impaired by trauma, disease, surgery or the like and do not longer maintain the transparency of the cornea, leading to edema and turbidity. Kyoto Prefectural University of Medicine and Doshisha University jointly expanded corneal endothelial cells derived from donors and injected them into the anterior chamber of patients with keratopathy. 11 cases of a clinical study now confirmed effectiveness and safety of this treatment.. AMED news release, March 15, 2018. ...
The Table summarizes the patients demographics, ocular comorbidity, concomitant treatment, and clinical manifestations including symptoms and signs at the presentation. Conjunctival inflammation was graded according to the conjunctival injection as none (0), mild (1), moderate (2), and severe (3). The corneal surface integrity was scored as clear (0), scattered superficial punctuate keratitis (SPK; 1+), moderate SPK (2+), and diffuse SPK with or without corneal epithelial defects (3+). The tear function was assessed by the fluorescein clearance test as reported28 using the Schirmer paper strip following topical application of 5 μL of Fluroress (Akorn Inc., Abita Springs, LA). The diagnosis of dry eye disease (DED) was based on the wetting length of less than 3 mm at the 10th and 20th minute. For Case #2 who presented with epithelial basement membrane dystrophy (EBMD), the diagnosis was confirmed by observing corneal epithelial wrinkles or breaks by the screwdriver test, which applies a dry ...
Recurrent Corneal Erosion (RCE) syndrome is a common, recurrent condition caused by abnormal epithelial adhesion to the underlying basal lamina. The spontaneous breakdown of the corneal epithelium can lead to the sudden onset of ocular pain, blurred vision, tearing, and photophobia, typically upon awakening.[1][2][3]
A limbal biopsy taken from the contralateral good eye in cases of unilateral disease or from a living related or cadaveric donor in cases of bilateral disease. The limbal stem cells from the biopsy are cultivated until a sheet of cells measuring approximately 12mm in diameter is obtained. This is then ready for transplantation onto the diseased eye ...

The results from this research may open the door to future therapeutics for a myriad of corneal disorders. It is essential to know the biochemical composition of normal healthy corneas in the effort to understand the molecular mechanisms behind corneal disorders, emphasizes Dr. Enghild. By comparative proteomic studies of diseased and normal corneas we can identify differences in the expression profiles that may suggest avenues for therapeutic interventions. Because the cornea is so accessible, the potential for developing effective drugs for the treatment of corneal diseases is good. Furthermore, the work is likely to improve the clinical classifications of corneal diseases. Identification of the protein profile of the normal human cornea may also be very useful in the effort toward generating artificial corneas for transplantation ...
