A pterygium is a non-cancerous growth of the conjunctiva that extends from the corner of the eye near the center of the eye.). One or both eyes may be involved. The pterygium can vary in appearance. It can range from a small hard to see tissue mass to a large red and very noticeable growth. Because pterygium varies in appearance it may be yellow, gray, white, pink, red, or even colorless. It may even have blood vessels.
The cause pterygium is unknown, but it is more common in people with increased outdoor exposure to sunlight and wind, such as those who work outdoors. Risk factors are exposure to sunny, dusty, sandy, or windblown areas. Farmers, fishermen, and people living near the equator are often affected. Pterygium is rare in children.

Treatment for Pterygium
When a pterygium becomes red and irritated, topical eye drops or ointments may be used to help reduce the inflammation. If the pterygium is large enough to threaten sight, is growing or is unsightly, it can be removed surgically. No-stitch surgery is possible by use of modern tissue adhesive. Often composed of clotting proteins from human blood the tissue adhesive allows the surgeon to secure an autograft in a short amount of time. Once the abnormal tissue is removed a thin graft of normal tissue is used to replace the damaged area. A pterygium can return after is has been removed.
Preventing a Pterygium
Protecting the eyes from ultraviolet light may help prevent this condition.
