Pinguecula and Pterygium
Pinguecula and pterygium are benign conjunctival growths that can result from chronic actinic irritation.
Pinguecula (left) is accumulation of conjunctival tissue at the nasal or temporal junction of the sclera and cornea.
Pterygium (right) is conjunctival tissue that becomes vascularized, invades the cornea, and may decrease vision due to obstruction or induced astigmatism.
