A pterygium is a noncancerous whitish-yellow growth on the white of the eye, the conjunctiva. It occurs horizontally on either side of the cornea. When it grows onto the cornea, it can blur one’s vision.
A pterygium is caused by dryness and or prolonged sun and wind exposure. If it results in chronic redness and irritation or decreased vision, the pterygium can be removed with surgery. The outpatient surgery involves removing the growth, sometimes with anti-scarring medication and or graft, to cover up space.
A bandage contact lens is placed over the eye for a couple of weeks to allow it to heal, and drops are taken to ensure an infection does not occur and reduce inflammation. When does in this fashion, the recurrence rate is reduced to 20%.
