Pterygium is a fibrovascular growth of tissue that extends from the white part of the eye (the sclera) onto the clear part of the eye (the cornea). Most pterygia grow from the nasal aspect of the cornea. Pterygia can interfere with sight by extending onto the cornea and impairing vision, they can also become recurrently irritated and inflamed. Pterygia are removed surgically and prevented from recurring by taking some of a patient’s own stem cells from the eye with a graft to prevent regrowth.
This operation is highly successful and usually gives an excellent cosmetic result.
