A pinguecula is a common type degenerative change in the conjunctiva of the eye.

(Strictly, "pinguecula" is the singular form of the noun, for which the pural is "pingueculae".)


Pingueculae are found most often in the elderly, especially in hot dry climates.

A pinguecula apperars as a small, yellowish nodule or even (eventually) a thickened deposit forming a whiteish-yellow triangle on the conjunctiva at the inner- and outer- margins of the cornea.

Treatment is not always necessary but expert diagnosis isrecommended, in part to avoid confusion with other more serious conditions that might require more urgent attention and action.
