Diagnosis: pterygium - temporal and nasal pterygia in an eye

Image Comments:

The usual location for a pterygium is the nasal limbus. Occasionally an eye will demonstrate pterygia both nasally and temporally. Rarely does a pterygium occur just temporally. In the photo the eye presents with nasal and temporal pterygia. The history of the pterygium is replete with analyses of its etiology and its treatment. The pterygium has frustrated many eye surgeons. At the moment, the technique of John A. Hovanesian, MD would seem to offer encouraging results. He employs a thin autograft of superior limbic conjunctival-corneal tissue containing stem cells. The autograft is glued to the bare sclera at the site of the dissected pterygium. The glue is a fibrin glue - Tisseel.This fibrin glue obviates the use of sutures in placing the autograft. A possible role for laser in pterygium treatment is also being evaluated by others.
