Pinguecula Overv(pin gwe’ cue la) is a benign, yellowish growth that forms on the white part of the
eye, or the conjunctiva. They usually grow near the cornea on the nasal side. Pingueculae
(plural form of pinguecula) are thought to be caused by ultraviolet light and are most common
among people who spend a great deal of time outdoors.
This growth does not affect vision, but may cause irritation if it becomes elevated. In rare cases,
the pinguecula may gradually extend over the cornea, forming a pterygium.
Signs and Symptoms
Pingueculae are harmless growths and rarely cause symptoms.
? Yellowish, raised area on the conjunctiva
? Irritation and scratchiness
? Dry eye
? Occasional inflammation of the conjunctiva
? Redness if the area becomes irritated
Detection and Diagnosis
Pingueculae can often be seen with the naked eye; however, the doctor examines the growth with
an instrument known as a slit lamp microscope.
Treatment
Because of their benign nature, pingueculae rarely require treatment. Occasionally, the growth may become inflamed, causing irritation and dryness. The doctor may prescribe artificial tears or steroid eye drops.
What is a pinguecula?
A pinguecula is a yellowish patch or bump on the white of the eye, most often on the side closest to the nose. It is not a tumor, but an alteration of normal tissue resulting in a deposit of protein and fat. Unlike a pterygium, a pinguecula does not actually grow onto the cornea. A pinguecula may also be a response to chronic eye irritation or sunlight.
How is a pingueculum treated?
No treatment is necessary unless it becomes inflamed. A pingueculum does not grow onto the cornea or threaten sight. If particularly annoying, a pinguecula may on rare occasions be surgically removed, but the postoperative scar may be as cosmetically objectionable as the pinguecula.
