Pterygium Guide

Pterygium are, proliferations of thick, triangular shaped, conjunctival connective tissue, which slowly grow in the eye.  Pterygia actually extend over the cornea and are less common compared with pinguecula, which is a similar condition.  If the pterygium have extended over the eye then vision may be impaired.  They are non-malignant and fairly common particularly with age but can also be found in children.
