A pingueculum is a common adult degeneration or thickening of the conjunctival tissue covering the white part of the eye. They consist of fatty deposits that develop in response to chronic surface irritation from a host of possibilities, such as, dryness, friction, contact lens wear, smoking and exposure to UV radiation. Pinguecula generally develop in the horizontal meridian on either side of the cornea and are more common on the nasal side.
Pinguecula are usually not a major concern but may increase in size, or become inflamed. Topical steroids, decongestants and lubricants may be used to relieve the redness or irritation that may occur. Pingeucula are rarely removed, as the trauma caused to the tissue often causes the condition to worsen or recur.
