Pterygium Current Concepts in Pathogenesis and Treatment

摘要

A pterygium is a commonly occurring ocular surface disorder, named for its resemblance to an insect wing. The multitude of treatment options currently advocated and practiced in different parts of the world is characterized by the absence of a universal approach. However, some of the traditional methods of treatment, such as bare sclera technique have fallen out of favor because of high recurrence rates (19.4% to 75%). Other adjunctive therapies, such as ?-irradiation and postoperative topical mitomycin-C, have also become less popular because of cost, operational issues or occurrence of serious complications such as scleral necrosis and intraocular infections.6"8 In recent years, new modalities of treatment have included conjunctival autografts (CAs), amniotic membrane transplantation (AMT) and fibrin glue instead of sutures. The purpose of this article is to present a summary of the currently advocated treatment options from a review of the recent literature.
