It is common in persons over age 35 years. Pterygium is a fleshy, triangular encroachment of the conjunctiva onto the cornea and is usually associated with prolonged exposure to wind, sun, sand, and dust (eFigure 7–22). Pinguecula and pterygium are often bilateral and occur more frequently on the nasal side of the conjunctiva.
