Pterygium vs. Pinguecula
Pterygium: fleshy triangular mass that extends to the cornea.
May interfere with vision.
Pinguecula: yellowish elevated bump or patch that does not grow across the cornea.
Treatment is not usually necessary but can be resected.
Both are conjunctival growths that may result from chronic actinic irritation, repeat trauma, or exposure to dry/windy conditions.
Typically occur on the nasal side.
They may cause irritation or cosmetic blemish.
