*Dr. Caccamise has very generously shared his images of patients taken while operating during the "eye season" in rural India as well as those from his private practice during the 1960's and 1970's. Many of his images are significant for their historical perspective and for techniques and conditions seen in settings in undeveloped areas.

Pterygium - temporal and nasal pterygia in an eye

pterygium - temporal and nasal pterygia in an eye

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.
