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.
