Understanding Pterygium
A pterygium is a wing-shaped, fleshy growth that appears to be growing on the iris of the eye. It is actually on the exposed surface of the conjunctiva, the membrane which covers the white of the eye and iris. Composed of fat and protein deposits, a pterygium may be yellow, gray, white, reddish or even colorless. It is almost always on the side of the eye closest to the nose. When the lesion is only on the white of the eye, it is known as a pinguecula.
There is no exact cause known for the development of a pterygium. People most at risk are individuals who spend a great deal of time outdoors, exposed to the sun as well as to environmental irritants like dust and wind. Farmers, fishermen, construction workers, golfers and gardeners are among those most susceptible.
Many patients with pterygium are concerned that the lesion is a malignant growth. While benign, it can cause excessive eye irritation. Inflammation, dryness, tearing, redness and foreign body sensation may all occur. A large pterygium can distort vision by causing astigmatism, and in some cases even block light from entering the eye. Often patients find pterygium to be cosmetically objectionable and feel very self conscious about their eye condition.
Pterygium treatment varies according its size. Artificial tears and eye drops may be used relieve the discomfort. Until recently, surgery was the only way to remove a pterygium. Unfortunately, the results have never been too encouraging. The recurrence rate has been about 40%, with the pterygium returning faster and larger. Today, Yaldo Eye Center offers a treatment option that is proving to be remarkable. It is a new injectable drug therapy that can reduce the size of and eliminate a pterygium.
The Board Certified Ophthalmologists at Yaldo Eye Center can diagnose a pterygium and rule out more serious eye growths during a complete medical eye examination. See what treatment is best for you at Yaldo Eye Center.
