A pterygium is a triangular growth of degenerative tissue on the white of the eye (sclera), usually on the nasal side, that may extend onto the clear window of the eye called the cornea.
A pterygium results from irritation due to long term exposure to ultra-violet light (UV), wind, glare or dust. Treatment is by eliminating the irritation with protective eyewear, eye-drops or surgery.
