Abstract
A pterygium is a wing-shaped growth from the conjunctiva that invades onto the cornea. The term comes from the Greek word ptergion meaning “wing”. It often appears as a yellowish or white elevated growth. A pterygium is a benign, i.e., noncancerous, growth. It is more common in dry, windy environments. It may also be related to ultraviolet light exposure. Several studies have shown a higher rate of pterygia in countries nearer the equator.
