A pinguecula is a raised yellowish bump on the white of the eye, usually on the nasal side. It is a buildup of elastic tissue in response to the irritation of UV exposure and dry environments. If the irritation continues they become a pterygium which is a growth extending over the cornea which can cause blindness. Sunglasses, UV absorbing lenses, lubricant drops and some medications are normally recommended for pingueculas. |
