I have search on the internet about Pinguecula and i found it at. Check it out for more information.


A pinguecula (pin gwe' cue la) is a benign, yellowish growth that forms on 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 diagnoses the growth with a careful examination with a slit lamp microscope.


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 for lubrication and mild anti-inflammatory medication to reduce swelling.

Definition of Pterygium and Pinguecula

A pterygium is a fleshy growth that invades the cornea (the clear front window of the eye). It is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea.

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.

A pinguecula is a type of conjunctival degeneration in the eye. It is extremely common and is seen as a yellow-white deposit on the conjunctiva adjacent to the limbus (the junction between the cornea and sclera). It is most prevalent in tropical climates and is in direct correlation with UV exposure.

Histologically it shows degeneration of the collagen fibres of the conjunctival stroma with thinning of the overlying epithelium and occasional calcification.

They may enlarge slowly but is a benign condition requiring no treatment. If cosmesis is a concern surgical excision is sometimes done.

A pinguecula is one of the differential diagnoses for a limbal nodule.
