A pinguecula is a small, yellowish nodule on the conjunctiva, which is the clear tissue that lays over the white part of the eye. It is a very common, non-cancerous growth most commonly caused from long-term sunlight exposure and that may increase in size over many years. An eye examination is often enough to diagnose this disorder. Lubrication with artificial tears is the only treatment normally needed. Sunglasses are the essential to reduce the incidence of pinguecula. -Susan
