What is Pinguecula?

A pinguecula is a common, non-cancerous growth of the conjunctiva (the mucus membrane lining the eyeball and underside of the eyelids). 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).

What are the symptoms of Pinguecula?

A pinguecula is a small, yellowish nodule on the conjunctiva near the cornea. It can appear on either side of the cornea, but usually appears on the nose (nasal) side. It may increase in size over many years.

What are the causes of Pinguecula?

The cause is unknown, but chronic sunlight exposure and eye irritation may contribute to its development. Welding is a significant occupational risk.

Treatment options

Usually no treatment is needed. Lubrication with artificial tears, and sometimes the temporary use of mild steroid eye drops can be helpful. Rarely, the growth may need to be removed if you have discomfort or for cosmetic reasons.
