View Video Pterygium is a pinkish, triangular tissue growth on the cornea. It’s unclear what causes pterygia, but since most people who develop pterygia usually have spent significant time outdoors, researchers believe chronic exposure to UV light from the sun may be a factor.
Wearing sunglasses, or a wide-brimmed hat in places of strong sunlight is your best defense against pterygium.
If you have one or more pterygia, lubricating eye drops may be recommended to reduce redness and soothe irritation.
North Carolina ENT has offices in Cary, Durham, Chapel Hill, Roxboro for treatment of Pterygium.
