Pinguecula and pterygium are growths on the conjunctiva of your eye. Pinguecula is a yellow spot or bump on the conjunctiva, often on the side of the eye near your nose. A pterygium is a fleshy growth that may start as a pinguecula. It can grow large enough to cover part of the cornea. Both are believed to be caused by exposure to ultraviolet (UV) light from the sun.
Treatment for pinguecula and pterygium may include lubricating eye drops or steroid eye drops. If a pterygium grows large enough to cause problems, surgery will be recommended to remove it.
The best way to keep pinguecula and pterygium from coming back is to avoid sunlight, dryness and dust.
