What is Pterygium?

A pterygium is a wing-shaped, fleshy growth that grows on 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. When the lesion is only on the white of the eye, it is known as a pinguecula.


There is no exact known cause for the development of a pterygium, but those most at risk spend a great deal of time outdoors exposed to the sun and to environmental irritants such as dust and wind. Farmers, fishermen, construction workers, golfers and gardeners are among those most susceptible.


A pterygium is completely benign, but it can cause excessive eye irritation, dryness, tearing, redness and a 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. Patients often find pterygium to be cosmetically objectionable and are very self-conscious about their eye condition.

Pterygium Treatment

 – Varies according to the pterygium size

 – Artificial tears and eye drops may be used relieve the discomfort

 – Until recently, surgery was the only way to remove a pterygium
