Pterygium, known as “surfer’s eye” is a pink wing-shaped growth from the conjunctiva onto the cornea. They typically start on the nasal side of the cornea, and are related to UV light exposure.  Symptoms and progression are usually controlled with topical lubrication, wearing sunglasses, and avoiding irritants, however if they cross into the visual axis or cause intolerable astigmatism they can be removed surgically.
