title: The clinical significance of a single unilateral temporal pterygium.
abstract: A rare case of a single temporal pterygium is reported. The etiology of pterygium and its predilection for the nasal side is discussed. A hypothesis is presented to explain why a pterygium never extends beyond the center of the cornea. Whenever a single temporal pterygium is noted it should be excised to determine the true nature of the lesion.
