Corneal Diseases: Diseases of the cornea.Nostrums: Medicines whose effectiveness is unproven and whose ingredients are often secret.Cornea: 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.

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: 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.BostonAwards and PrizesMassachusettsTranslational Medical Research: The application of discoveries generated by laboratory research and preclinical studies to the development of clinical trials and studies in humans.

It is a homogeneous structure composed of fine collagenous filaments, and slowly increases in thickness with age.Basement Membrane: A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue.

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)

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 ...

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. This review presents recent findings in assessing the ocular surface as well as the
I took my defect a little longer to heal, (I dont know if it was because the flap was lifted before it healed) ,it healed rapidly and then slowed. 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 ...

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. ...

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 ...
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 ...
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 ...

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 ...

Ocular surface is composed of corneal and conjunctival epithelial cells. Normal cornea is essential for normal vision. Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia, repeated and persistent surface breakdown and overt conjunctivalisation of the cornea. Restoring ocular health in these eyes has traditionally been frustrating. Ex vivo cultured limbal epithelial stem cells have been used successfully to treat limbal stem cell deficiency. Ex-vivo limbal stem cell allograft transplantation is achieved by harvesting limbal corneal tissue from donor eyes (either matched living relatives or cadaveric donors). The donor stem cells are obtained by excising a small area of the conjunctiva at the limbus and are a minor procedure. The tissue so obtained is then grown in tissue culture and once the cells have multiplied sufficiently, small sheets are transplanted on to the ...
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
Overview Iridocorneal Endothelial Syndrome (ICE) is a grouping of three closely linked conditions: Iris Nevus (or Cogan-Reese Syndrome), Chandlers Syndrome and Essential Progressive Iris Syndrome. There are three main features of ICE: visible changes of the iris, swelling of the cornea and the development of glaucoma, which can cause severe vision loss. Warning Signs & Symptoms ICE causes corneal swelling, distortion of the iris and variable degrees of distortion of the pupil, the adjustable opening at the center of the iris that allows varying amounts of light to enter the eye. This cell movement also plugs the fluid outflow channels of the eye, causing glaucoma. Treatment/Procedures While it is not yet known how to keep ICE syndrome from progressing, the glaucoma associated with the disease can be treated with medication, and a corneal transplant can treat the corneal swelling.. Prevention The cause and prevention of this disease is unknown. Rehabilitation If a corneal transplant is required, ...
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 ...
PURPOSE: To determine the epithelial phenotype in patients with a limbal stem cell deficiency (LSCD) after ocular surface reconstruction with autologous cultured stem cells. To correlate the epithelial phenotype with the clinical outcome.. METHODS: Six eyes affected by LSCD, verified and graded by impression cytology, were treated with an autologous fibrin-cultured limbal stem cell graft. The clinical outcome was defined as a "success" or a "failure," depending on ocular surface stability. To improve their visual function, 4 patients underwent lamellar or penetrating keratoplasty after the stem cell graft. The phenotype of the regenerated corneal epithelium was determined by immunofluorescence of the corneal button to detect CK12, CK3, CK19, and Muc1 as corneal and conjunctival markers.. RESULTS: After a mean follow-up of 24 months, 5 cases were defined as successes; 1 case presented an epithelial defect 4 months after grafting and was defined as a failure. Immunofluorescence performed on 4 ...
In corneal transplant, also known as keratoplasty, a patients damaged corneais replaced by the cornea from the eye of a human cadaver. This is the single most common type of human transplant surgery and has the highest success rate. Eye banks acquire and store eyes from donor individuals largely to supplythe need for transplant corneas.. Corneal transplant is used when vision is lost in an eye because the cornea has been damaged by disease or traumatic injury. Some of the disease conditions that might require corneal transplant include the bulging outward of the cornea (keratoconus), a malfunction of the inner layer of the cornea (Fuchs dystrophy), and painful swelling of the cornea (pseudophakic bullous keratopathy). Some of these conditions cause cloudiness of the cornea; others alter itsnatural curvature, which can also reduce the quality of vision.. Injury to the cornea can occur because of chemical burns, mechanical trauma,or infection by viruses, bacteria, fungi, or protozoa. Herpes ...
It has been increasingly recognized that the corneal nerves play a key role in maintaining the anatomical integrity and functions of the cornea. Corneal nerve damage can lead to transient or chronic neurotrophic deficits with a decrease in the viability, metabolism, and rate of mitosis of the epithelial cells. This may result in epithelial intracellular swelling, loss of microvilli, and abnormal production of the basal lamina. As a consequence, symptoms of dry eye, corneal damage and infection develop known as neurotrophic keratopathy (NK) [1],[2].. The vast majority of the corneal nerves are derived from the ophthalmic branch of the trigeminal nerve [4]. Therefore, NK can be induced by any damage to the corneal sensory nerve pathways [1],[2]. The most common cause of NK is the peripheral corneal sensory nerve injury induced by viral infection, refractive surgery, chemical or thermal burns, ocular medication, and wearing contact lenses. Moreover, NK may develop from the damage of the ophthalmic ...
Our purpose was to evaluate the diagnostic value of three-dimensional (3 D) CT surface reconstruction in spinal fractures in comparison with axial and reformatted images. A total of 50 patients with different CT-proven spinal fractures were analysed retrospectively. Based on axial scans and reformatted images, the spinal fractures were classified according to several classifications as Magerl for the thoraco-lumbar and lower cervical spine by one radiologist. Another radiologist performed 3 D CT surface reconstructions with the aim of characterizing the different types of spinal fractures. A third radiologist classified the 3 D CT surface reconstruction according to the Magerl classification. The results of the blinded reading process were compared. It was checked to see in which type and subgroup 3 D surface reconstructions were helpful. Readers one and two obtained the same results in the classification. The 3 D surface reconstruction did not yield any additional diagnostic information concerning type
Purpose: To evaluate the anatomic stability of an implanted Boston Type I Keratoprosthesis (KPro)-donor cornea interface, and assess the presence or absence of a potential space (gap) between the KPro front plate and donor cornea using anterior segment optical coherence tomography (AS- OCT). The presence of a gap would raise concerns of a possible pathway for the exchange of fluid between the ocular surface and the anterior chamber.. Methods: Fourteen eyes implanted with a Boston Type I KPro were studied by the non-contact technique of AS-OCT (AC Cornea OCT prototype, OTI, Canada). All the KPro devices had been implanted at least 4 weeks prior to the study (range: 1 to 22 months). Seven eyes had aphakic Kpros and the other 7 had pseudophakic implants. Anesthetized eyes were imaged before and during pressure application using sterile cotton tip applicators. Pressure was applied for 10 seconds just outside the temporal limbal area. Images were analyzed for any possible changes in the KPro-donor ...
Eye Physicians of Central Floridas Lynda Z. Kleiman, M.D., David B. Auerbach, D.O. and Victor B. Thomas, M.D. are ophthalmologists who specialize in corneal diseases and surgery. Lynda Z. Kleiman, M.D. is our fellowship-trained corneal and external diseases specialist.. Corneal care focuses on infections, injuries and disease of the cornea -- the clear, round, "window" of tissue that allows light to enter the front of the eye. Many conditions can affect the cornea and lead to decreased or distorted vision. Sometimes the vision can be improved with glasses, contact lenses or medication.

Due to its noninvasive accessibility and clarity, cornea serves an ideal target for evaluating the efficacy of various treatments against corneal disorders. A multitude of potential gene therapies based on different genes and strategies have been tried in the context of corneal diseases, including corneal NV. For example, various viral-mediated gene delivery systems have been proposed to produce expression of the desired genes with varying expression levels and duration [32-34]. In the case of gene therapy for corneal NV, as in many other situations, it is well recognized that targeting a single gene often fails to ensure the theoretically predicted efficacy [23,35-37]. We therefore investigated the possibility of better management of corneal NV by combining different anti-angiogenic factors in the present study. We showed that the combination of two or three genes exhibited additive effects over a single gene in inhibiting HUVEC proliferation in vitro (Figure 1A). This additive effect, however, ...

This video shows a cornea with amiodarone verticillata deposits. You can see these as a whorl pattern - the entity is also called whorl keratopathy or hurricane keratopathy. These deposits are benign, difficult to see, and rarely (if ever) have any visual significance.. Drugs that can cause this pattern: CACTI Mneumonic: chloroquine, amiodarone, chlorpromazine, tamoxifen, indomethacin.. In addition, you can presumably get a similar pattern with amodiaquine, meperidine, and with Fabrys disease.. ...

Well, it appears the saga of my cat-and-book-induced eye injury is not quite over, after all. As reported here earlier, the injury itself seemed to heal up nicely in a few days, but recently Ive started noticing that when I look at a bright light against a dark background, Im getting some mildly disturbing blurring effects, and, in certain circumstances, a sort of faint second image of the bright object, just with that one eye. So, like the conscientious patient I occasionally am, I went in to see the optometrist. He didnt confirm any of my paranoid hypochondriac worries, thank goodness. (Yes, I will admit that part of my brain kept going, "Aaargh, Im developing a cataract! Maybe its glaucoma! Help, my retina is detaching!") He said the cornea looks nice and healed up, but there is some "degradation in the epithelium" and that I am at risk for something called recurrent corneal erosion. Which means, basically, that your eyeball sticks to your eyelid, especially when youre asleep, and then ...

To present a method, alternative to penetrating keratoplasty, for the restoration of impaired corneal clarity with anterior stromal scarring following long-standing corneal graft failure. A 48-year old female who had previously underwent Descemet stripping automated endothelial keratoplasty (DSAEK) for the treatment of pseudophakic bullous keratopathy, presented with long-standing corneal oedema and anterior corneal scarring. A significant improvement in corrected distance visual acuity was demonstrated, as corneal clarity was restored following graft exchange and phototherapeutic keratectomy (PTK). The combination of corneal graft exchange and phototherapeutic keratectomy may represent an effective therapeutic option for long-standing corneal oedema with concomitant anterior corneal scarring after failure of a DSAEK graft.
Purpose: To describe outcomes of corneal transplantation for irreversible corneal decompensation from corneal endotheliitis in Asian eyes. Design: Retrospective, observational case series. Methods: We reviewed consecutive patients with corneal endotheliitis (32 eyes of 31 subjects) who underwent keratoplasty (January 1, 2008-December 1, 2009). All eyes had preoperative aqueous polymerase chain reaction (PCR) analysis for viruses, including cytomegalovirus (CMV). CMV-positive patients were treated preoperatively with topical corticosteroids and anti-CMV treatment (oral valganciclovir 900 mg twice daily, topical ganciclovir 0.15% 5 applications per day, for 6 weeks) with complete resolution of ocular inflammation, and quiescence for at least 6 months before corneal transplantation. Our main outcome measure was recurrence of endotheliitis within 1 year after corneal transplantation. Results: Five eyes were CMV positive; the remaining 27 eyes were negative for all viruses on PCR analysis. ...
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 visually significant corneal opacification from Macular Corneal Dystrophy.. ...
What is a corneal transplant?. A corneal transplant is where the abnormal cloudy or scarred patients cornea is removed and a donor cornea (the clear window on the front of the eye, which has been obtained from someone who has donated their cornea) replaces the abnormal patients cornea.. When is a corneal transplant needed?. A corneal transplant may be needed when the cornea is permanently scarred, or the corneal shape is very abnormal (as in keratoconus) or when the endothelial pumping cells at the back of the cornea are not functioning well (as in Fuchs dystrophy). A corneal transplant (also known as a corneal graft) is only worth doing when the inside of the eye (retina and optic nerve) is still functioning well. The camera analogy is that there is no purpose in replacing the clear lens in the camera if the photographic components are not working. Conditions that may have damaged the inside of the eye are glaucoma, optic nerve disease, retinal detachment, severe inflammation or infection ...

DSAEK surgery is considered a valuable alternative to PK in cases of dysfunctional endothelium such as in Fuchs dystrophy as it selectively replaces it. DSAEK is less invasive and better tolerated by patients [4], allows prompt improvement and stability of visual acuity. However, being a lamellar surgery, it creates an interface between the donor and the recipient tissue, where the healing process is thought to be critical to optimal visual recovery [11]. DSAEK grafts present increased haze at least up to three months, when compared to PK grafts [12]. Loss of corneal transparency and swelling in Fuchs dystrophy have been object of extensive studies [13].. The most common cause of DSAEK failures is secondary to endothelial cell loss, followed by "dysfunctional" donor-host interface. These include lenticule dislocation, interface fibrosis or hemorrhage, epithelial downgrowth [14-16].. LCM is a low-invasivity, repeatable method which allows to study the interface histology in vivo, and hence is ...
Therapeutic contact lenses are useful in a variety of ocular surface diseases. Their main indications are: to relieve the pain; protect ocular surface; promote corneal healing and epithelial regeneration; seal a leaking corneal wound and deliver ophthalmic drugs on the ocular surface. There are several kinds of lens designs and materials, and their choice is dependent on the specific disease to be treated, the duration of treatment and the physiologic needs of the diseased cornea. Bullous keratopathy, recurrent epithelial erosion syndrome, dry eye and postoperative epithelial defects are amongst their indications. Therapeutic contact lenses should not be indicated in the presence of active infectious keratitis or when the patient is not compliant. Corneal neovascularization, giant papillary conjunctivitis and infectious keratitis are serious complications, which can be prevented by correctly fitting and maintaining the therapeutic contact lenses. Silicon-hydrogel therapeutic contact lenses, due ...
VAN DYK, M e MEYER, D. Hutchinsons sign as a marker of ocular involvement in HIV-positive patients with herpes zoster ophthalmicus. SAMJ, S. Afr. med. j. [online]. 2010, vol.100, n.3, pp.172-174. ISSN 2078-5135.. BACKGROUND: A positive Hutchinsons sign indicates an increased risk of ocular involvement in herpes zoster ophthalmicus (HZO). We examined the sensitivity of Hutchinsons sign as an indicator of ocular involvement in a consecutive series of patients presenting with HZO. METHODS: We conducted a descriptive observational prospective study of patients ,18 years old presenting with HZO and consenting to pre- and post-test counselling and HIV and CD4 testing. A full ophthalmological examination focused on the extent of ocular involvement, and the presence of Hutchinsons sign was confirmed by two clinicians. RESULTS: Thirty-three patients were enrolled; 29 were HIV positive, of whom 18 (62%) had not been diagnosed with HIV prior to enrolment. Of the 29 HIV-positive patients, 21 (72%) were ...
Limbal epithelial stem cells (LESCs) are tissue-specific stem cells responsible for renewing the corneal epithelium. Acute trauma or chronic disease affecting LESCs may disrupt corneal epithelial renewal, causing vision threatening and painful ocular surface disorders, collectively referred to as LESC deficiency (LESCD). These disorders cannot be treated with traditional corneal transplantation and therefore alternative cell sources for successful cell-based therapy are needed. LESCs derived from human pluripotent stem cells (hPSCs) are a prospective source for ocular surface reconstruction, yet critical evaluation of these cells is crucial before considering clinical applications. In order to quantitatively evaluate hPSC-derived LESCs, we compared protein expression in native human corneal cells to that in hPSC-derived LESCs using isobaric tag for relative and absolute quantitation (iTRAQ) technology. We identified 860 unique proteins present in all samples, including proteins involved in cell ...
Varicella zoster virus (VZV) causes two distinct viral syndromes. VZV infection is a common and usually benign childhood infection, manifesting as chickenpox. Herpes zoster ophthalmicus (HZO) is a potentially devastating visual disease with variable presentation caused by the re-activation of a latent infection of the trigeminal ganglion by the VZV.. The most common causes of re-activation of VZV are decreased cell-mediated immunity related to age, malignancies, chemo- or radiotherapy, HIV infection, and the use of immunosuppressive drugs.1 The characteristic vesicular cutaneous involvement in the area supplied by the ophthalmic division of the trigeminal nerve with respect to the horizontal midline is usually the first clinical sign and is often preceded by pain in this area caused by viral replication in the ganglion.. Hutchinsons sign results from the involvement of the skin and/or nasal mucosa of the tip of the nose on the ipsilateral side of the HZO infection. This involvement of the ...
Pre Descemets endothelial keratoplasty (PDEK) is a kind of endothelial keratoplasty, where the pre descemets layer (PDL) along with descemets membrane (DM) and endothelium is transplanted. Conventionally in a corneal transplantation, doctors use a whole cornea or parts of the five layers of the cornea to perform correction surgeries. In May 2013, Dr Harminder Dua discovered a sixth layer between the stroma and the descemet membrane which was named after him as the Duas layer. In the PDEK technique, doctors take the innermost two layers of the cornea, along with the Duas layer and graft it in the patients eye. The normal cornea (Fig 1) has from the front to the back the following layers: 1. Epithelium 2. Bowmans membrane 3. Stroma 4. Pre Descemets layer 5. Descemets membrane 6. Endothelium For the human eye to see, the cornea or the front window of the eye should be clear or transparent. For that to happen the inside corneal layer the endothelium pumps out water from the cornea so that the ...
Thicker corneas and steeper posterior corneal curvature were seen in eyes that underwent Descemets stripping automated endothelial keratoplasty compared with eyes that underwent Descemets membrane endothelial keratoplasty, according to a study. The retrospective study included 20 eyes of 10 patients with Fuchs endothelial dystrophy who underwent DSAEK in one eye and DMEK in the contralateral eye. Four DMEK eyes and three DSAEK eyes had cataracts that were removed concurrently with corneal transplantation. Four DMEK eyes and four DSAEK eyes were pseudophakic and had posterior chamber IOLs. Two DMEK eyes and (Read more...) Full Story →. ...
