A pterygium is a fleshy tissue that grows over the corne ( the clear front window of the eye).  It may remain small or may grow large enough to interfere with vision.  A pterygium most commonly occurs on the inner corner of the eye, but can appear on the outer corner as well. The exact cause is not well understood.  Pterygium occurs more often in people who spend a great deal of time outdoors, especially in sunny climates.  Long-term exposure to sunlight, especially UV rays and chronic eye irritation from dry, dusty conditions seem to play an important role.  A dry eye may contribute to a pterygium growing. when a pterygium becomes red and irritated, eyedrops or ointments may be used to help reduce inflamation.  If the pterygium is large enough to threaten sight, grows or is unsightly, it can be removed surgically. despite proper sugical removal, the pterygium may return, particularly in young people.  Surface radiation or medications are sometimes used to help prevent recurrences. Protecting the eyes from excessive UV light with proper sunglasses and avoiding dry, dusty conditions along with artificial tears may also help.
