BACKGROUND/AIMS Bare sclera resection with and without use of mitomycin C and conjunctival autograft placement are three surgical techniques currently in use for the treatment of primary pterygium. The purpose of this study was to determine through a meta-analysis the risk for postoperative pterygium recurrence comparing the three surgical treatment modalities. METHODS A search through Medlin...

Purpose: To evaluate the outcomes of primary pterygium excision with adjunctive amniotic membrane transplantation. Methods: In an interventional case series, consecutive patients with primary pterygia underwent surgical excision with transplantation of preserved amniotic membrane onto bare sclera. Patients were followed for at least 12 months and the results were evaluated in terms of recurrent...

Abstract Introduction: The aim of this study was to clinically evaluate lid margin abnormality, meibomian glands expression and tear function changes in patients with primary pterygium. Methods: Fifty normal 50 pterygia participants without other ocular pathologies were randomly selected from who attended an ophthalmology visit. gland expression, break-up time, Schirmer's test results surface d...

PURPOSE To demonstrate the long term of follow-up of the recurrence rate after conjunctival autograft for pterygium surgery. METHODS A total of 112 patients operated for pterygium with conjunctival autografts and with more than one year follow-up were registered. Patients were called for voluntary examinations of their respective ocular surface statuses. Completing the study was only possible...

OBJECTIVE The objective of this study is to present the 3 months results of pterygium excision with adjunctive amniotic membrane graft. MATERIALS AND METHODS In a non-comparative case series study, the medical records of all patients who had pterygium excision with adjunctive amniotic membrane transplant on bare sclera from December 2009 to August 2010 were reviewed. All the patients were fol...

PURPOSE To investigate the effect of pterygium surgery on corneal topography and contrast sensitivity. PATIENT AND METHODS The IRB approved this prospective, nonrandomized, self-controlled study. Computerized videokeratography (Orbscan II) was performed in 36 patients with primary pterygia, both before and 1 month after pterygium excision with limbal-conjunctival autografting. The topographic...

PURPOSE Following the recent discovery of an abnormal expression of the p53 gene in the epithelium in pterygium, some researchers felt that pterygium is a tumor rather than a degenerative disease. Ultraviolet (UV) radiation has been reported to be associated with pterygium formation, however the mechanism whereby UV induces uncontrolled proliferation in pterygial cells is unclear. Because cyclo...

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 whi...

PURPOSE Pterygium was traditionally regarded as a degenerative disease, but certain characteristics suggest that pterygium is probably premalignant tissue. The human WWOX gene, encoding the WW domain containing oxidoreductase (WWOX, FOR, or WOX1), is a candidate tumor suppressor gene. In this study, we investigated the WWOX gene and protein expression in pterygium. METHODS Pterygium tissues w...
