Squamous metaplasia is an abnormal epithelial differentiation represented on the ocular surface by a spectrum of skin-like changes of conjunctival and corneal epithelium. This pathologic condition can be observed in a variety of ocular surface disorders, including systemic vitamin A deficiency and cicatricial keratoconjunctivitis. We recently encountered a patient with a progressively enlarging...

The human ocular surface (front surface of the eye) is formed by two different types of epithelia: the corneal epithelium centrally and the conjunctival epithelium that surrounds this. These two epithelia are maintained by different stem cell populations (limbal stem cells for the corneal epithelium and the conjunctival epithelial stem cells). In this review, we provide an update on our underst...

AIM To assess the effect of topical bevacizumab use on postoperative pterygium recurrence in eyes who underwent pterygium excision with limbal-conjunctival autograft transplantation (LCAT). METHODS Eighty-eight eyes of 88 patients with primary pterygium were included. Pterygia were graded preoperatively from type 1 to type 3 (type 1 atrophic, type 3 inflamed) according to the inflammatory sta...

Background: Recurrent pterygium poses distinct problem like high postoperative recurrences and many surgical approaches have been tried to decrease recurrences. Currently, mitomycin C (MMC) application and amniotic graft are used as adjunct apart from the standard limbal-conjunctival autograft. Aim of study: Aim of this study is to determine through meta-analysis, the risk of recurrences and fr...

Total bilateral Limbal Stem Cell Deficiency is a pathologic condition of the ocular surface due to loss corneal stem cells. Cultivated oral mucosa epithelial transplantation (COMET) only autologous successful treatment for this pathology in clinical application, although abnormal peripheric vascularization often occurs. Properly characterizing regenerated needed reliable follow-up. So far, univ...
