Pinguecula: Causes, Symptoms, Treatment, and Prevention

A pinguecula is a yellowish, raised bump on the sclera (usually nasal side) from protein/fat deposits under the conjunctiva. It's benign and common with age/sun exposure.

Management:

• Usually none needed.
• Lubricating drops for irritation.
• Rarely, surgical removal if vision threatened or severe discomfort.

Prevention: UV-blocking sunglasses, no smoking, hydration, antioxidant-rich diet.
