A pterygium is a growth on the transparent outer layer of the eye, the conjunctiva. A pinguecula is actually degenerated tissue, and usually appears as a yellowish-brown mass. However, a pterygium may progress and grow onto the cornea posing a visual threat. For either condition and also cosmetic reasons, surgical excision of a pterygium may be indicated. Symptoms from pterygia or pinguecula may range from mild to severe.
Symptoms can include blurred vision, irritation, dryness, itching, and burning.
The most common symptoms are irritation and a dry, gritty feeling. Prevention measures are by far the best methods of treatment. Prevention includes wearing hats and sunglasses when outdoors on windy or sunny days. But, if treatment is necessary, drops relieve dryness, redness, irritation and inflammation. Often, surgery is not necessary.
