A pterygium is a fleshy reddish growth on the surface of the eye.  It starts in the conjunctiva, which is the thin membrane that covers the white part of the eye.  As the pterygium grows, it enters the cornea, which covers the colored part of the eye.  It usually has a triangular shape, which explains the origin of the word “pterygium”, which is Greek for “wing”.  In over 90% of cases, it starts in the inside corner of the eye.  Pterygium growth is thought to be due to years of exposure to the ultraviolet radiation from the sun.  Pterygia are seen frequently in people who spend much time outdoors or are from tropical climates.

People with pterygia usually notice chronic redness, usually in the inside corner of the eye.  As a pterygium grows, it can cause chronic irritation.  An advanced pterygium can cause double vision or visual loss.

A small or minimally troublesome pterygium can often be managed simply by using artificial tears to lubricate the eye.  However, a larger pterygium that is causing problems often requires surgical removal.  Surgical techniques are designed to maximize the cosmetic and functional result, while minimizing the chance of recurrence.
