A<unk>  is a non-cancerous, whitish-pinkish, and triangular-shaped tissue growth on the conjuntiva.  Although it typically grows from the nasal side of the eye inward, it rarely grows so large that it begins to cover the pupil of the eye.  Some pterygia grow slowly throughout a person's life, while others stop growing after a certain point.  One or both eyes may be involved.
