Strategies in Pterygium Treatment

Pterygium is a conjunctival degenerative process characterized by a sheet of fibrovascular tissue encroaching upon the cornea within the inter-palpabral fissure, almost invariably on the nasal side. Excessive exposure to ultraviolet sunlight is the most common predisposing factor. Ultraviolet light induced damage to limbal stem cell barrier with subsequent conjunctivilization of the cornea is the current accepted etiology. Other agents that give rise to chronic irritation of the conjunctiva such as air pollution, dust and wind have also been found as determining factors [1]. JMS 2014;17(1):4-5
