Pinguecula: An Overview

Pinguecula is a benign elevated lesion (yellowish-white) of the bulbar conjunctiva that is usually situated on the nasal or temporal side and close to the limbus. It is a degenerative disease that has elastotic degeneration of the conjunctival stroma and is clinically and pathologically distinct from pterygium, which extends across the limbus to the cornea, usually bilateral and located interpalpebral.
