Purpose A new device for epithelial abrasion before excimer laser surface ablation or corneal cross-linking (CXL) has recently been introduced (Epi-Clear™, Orca Surgical, Kiryat-Shmona, Israel). We have reviewed the literature on the clinical results, potential benefits and drawbacks of this instrument, compared to other methods of epithelial removal. Method Literature search for "Epi-Bowman Keratectomy", "Epi-clear", and "Epikeratome" yielded 1 peer-review publication, 1 non-peer-review publication, 18 posters and presentations at international conferences (European Society of Cataract and Refractive Surgeons [ESCRS] and American Society of Cataract and Refractive Surgery [ASCRS]) on the use of the Epi-Clear™ device before surface ablation, 2 posters on the use of Epi-Clear before corneal crosslinking and 1 presentation on the experimental use of Epi-Clear for removal of a pterygium...

Popliteal pterygium syndrome is a condition characterized by skin webs of skin on the popliteal fossa, which may impair mobility unless surgically repaired. Affected individuals may also have syndactyly on the fingers and/or toes. Most people with this disorder present cleft lip and cleft palate and they can have syngnathia, which is a congenital adhesion between maxilla and mandible by fibrous bands, which affects the opening of the mouth. The case that we report is about a 2-month-old male, who presented skin webs bilaterally on the popliteal fossa, syndactyly between the IV and the V toe of the right foot and between the III and the IV toe of the left foot, and genital malformations...

BACKGROUND: We report a rare case of carcinoma in situ (CIS) in conjunction with a primary pterygium that exhibited characteristic angiographic and histopathological findings. CASE: A 78-year-old man presented with a pterygium and a whitish tumor adjacent to the pterygium in his right eye. Indocyanine green angiography displayed that feeder vessels within the primary pterygium spread to the whitish tumor. The tumor and pterygial tissues were surgically removed. Histologically, the resected tissue contained CIS as well as squamous metaplasia...

Onychodystrophy is a common, chronic malformation of the nail that is aesthetically displeasing and can signi cantly impact patient quality-of-life. Onychodystrophy can be associated with pterygium unguis that contributes to pain and appears as a V-shaped exten- sion of the proximal nail fold skin. Treatment options are limited, and topical or intralesional corticosteroids have minimal ef cacy and cause signi cant patient discomfort. Surgical revision of onychodystrophy is complex, and symptomatic or aesthetic improvements are difficult to achieve...

We examined the connection between matrix metalloproteinase (MMP) expression/activity and pterygium fibroblast migration, and how these were affected by bevacizumab and/or cyclosporine A (CsA). Fibroblasts were obtained from 20 pterygia and 6 normal conjunctival specimens. Expression levels of MMP-3 and MMP-13 were examined after bevacizumab administration. Immunofluorescence staining was used to examine expression of both MMPs in fibroblasts migrating out from explanted pterygium tissues. Rates of cell migration from explant-cultured pterygia tissues and scratch-wounded confluent pterygium fibroblasts were examined in the presence of MMP-3 or MMP-13 inhibitors, as well as bevacizumab and/or CsA...

Cleft lips, alveolar ridges and palates are among the most common birth defects. There are over 500 different complex genetic disorders that include cleft defects. The most common related defects include abnormalities of the skeleton, skull, cardiovascular and nervous system. The occurrence of a cleft results from the interplay of multiple genes and environmental factors. Several thousand different mutations responsible for these syndromes have been discovered, whereas there are still numerous phenotypic cases of unknown genetic origin...

The study of ocular diseases and epigenetic dysregulation is an emerging area of research. The knowledge from the epigenetic mechanisms of DNA methylation, histone modifications, chromatin remodeling, and non-coding RNAs regarding the pathogenesis of ocular diseases will be helpful for improved treatment modalities for our patients. In particular, we focus upon the how epigenetic regulatory mechanisms impact five common ocular diseases: age related macular degeneration, age-related cataract, pterygium, retinoblastoma, and uveal melanoma...

Numerous reports point to Demodex mites as the aetiology of certain eye and skin conditions, hence it is highly probable that infestation with these mites may also play a role in the aetiology and pathogenesis of pterygium. Therefore here we present a hypothesis: whether the presence of Demodex mites in eyelash hair follicles significantly correlates with the presence of pterygia, which could point to a potential role of these mites in the development of such lesions. We present preliminary data for supporting this hypothesis...

BACKGROUND: Nail involvement has rarely been recognized in systemic sclerosis (SSc). Indeed, only a few small series have assessed nail changes in SSc, most of which are case reports. OBJECTIVE: The aims of the current case-control study were to: (1) determine the prevalence of fingernail changes in SSc; and (2) evaluate the correlation between fingernail changes and other features of SSc. METHODS: In all, 129 patients with SSc and 80 healthy control subjects underwent routine fingernail examination...

The aim of surgery for pterygium colli (PC) is to correct the contour deformity, redistribute or remove the horizontal excess of skin, address the abnormal posterior hairline, avoid excessive scarring, and prevent recurrence. The purpose of this study is to review the available methods to correct the deformity and highlight a recent patient performed by the senior author. A modified bilateral Z-plasty technique was used for correcting PC on a 5-year-old African American girl diagnosed with Turner syndrome. The patient had an uneventful postoperative period and satisfactory functional and esthetic results were demonstrated at 1 year follow-up...

Lethal multiple pterygium syndrome (LMPS) is a fatal hereditary disease associated with abnormalities such as pterygium-induced congenital contractures. Fetal hydrops is present in more than half of all patients with LMPS, and all patients with LMPS are either stillborn or die in the early neonatal period. Ultrasonography findings for the prenatal diagnosis of LMPS include the detection of cutaneous webbing at multiple joints, multiple joint contractures, absent limb movement, and increased nuchal translucency...

The authors present a case of necrotizing scleritis after pterygium excision successfully treated with rituximab after attempts with high doses of corticosteroids and immunosuppressive drugs. A literature review revealed case reports and a phase I/II dose-ranging randomized clinical trial using rituximab for necrotizing scleritis with or without association with autoimmune disease. This is the only case report on rituximab treatment for necrotizing scleritis after pterygium surgery. In cases with refractoriness to immunosuppressive drugs, a CD20 antibody can be used...
