Pinguecula

Definition: A pinguecula is a slightly raised, benign yellowish thickening of the white part of the eye (conjunctiva) adjacent to the cornea.

Cause: Pinguecula are typically caused by repeated sun and wind exposure. For this reason, they are more common in people who have worked outside for their occupations or come from more southern climates.

Symptoms: Pinguecula are usually asymptomatic. Occasionally, they may become inflamed, causing irritation and redness of the eye. Sunglasses may be helpful in preventing further growth. Some pinguecula may slowly get bigger, growing onto the cornea and becoming a pterygium, which can cause decreased vision.

Treatment: Most pinguecula do not need treatment. Occasionally, artificial tears and possibly ibuprofen drops will be prescribed if the pinguecula is inflamed, irritated or causing dryness. Occasionally if they are very highly elevated, surgery may be used to remove the pinguecula.

Prognosis: Most pinguecula do not increase in size or progress to pterygia. Some may decrease in size with time.
