Definition of Pinguecula

Pinguecula is a thickened area of the conjunctival tissue on the eye, usually forming on the inner (nose) side of the eye. A pinguecula may be clear, yellow, or gray in color, and develops slowly. It presents no threat to vision or the eye, and is more common in people over age 50.

Symptoms and treatment

Many people do not notice that they have pingueculae or consider them normal features of their eyes, though some people experience irritation and a sensation of grittiness in the affected eye. People who spend a lot of time in the sun or have other long-term ultraviolet light exposure are more likely to develop a pinguecula.

Ophthalmologists recommend wearing sunglasses or protective eyewear that filters ultraviolet light. There is no reason to treat a pinguecula unless it puts pressure on the cornea or otherwise interferes with vision.
