Pterygium
Description
A non-cancerous growth that involves the conjunctiva. The conjunctiva is the white part of the eye surrounding the colored part of the eye (iris). The pterygium is white to yellow in color and grows onto the iris. They tend to grow slowly and usually do not affect the vision of the eye. Having more exposure to sun light such as living near the equator or working outside increases the likelihood of developing pterygium. The disorder occurs twice as often in males as females and is rarely seen before the age of 20.
Symptoms
Many patients do not have any symptoms. Others experience: eye redness, foreign body sensation, swelling, itching, and blurry vision.
Tests
A history and physical exam will be done. A examination using a slit lamp may be performed to rule out any other growths or problems with the eye.
Treatment
Surgery to remove the pterygium is done when the vision is affected, if symptoms recur, or for cosmetic reasons.
