What is a pterygium?

A pterygium is a growth of tissue that occurs on the surface of the eye. It originates from the clear conjunctival tissue that covers the white part of the eye and is most commonly located on the exposed surface of the eye closest to the nose. The eye may appear more red in the area where the ptyergium is located, or feel slightly irritated or dry.

Sometimes pterygia can grow over the cornea (clear front surface of the eye) causing vision to be obstructed or astigmatism to be produced. If this occurs the pterygium can be removed surgically by an eye specialist (ophthalmologist).
