What Is Pterygium?
Pterygium Symptoms
A small pterygium may cause no symptoms. When symptoms occur, they may include:
- A visible fleshy growth on the surface of the eye
- Redness and irritation
- A gritty or foreign-body sensation
- Blurred vision if the growth changes the shape of the cornea or extends towards its centre
An eye examination can assess the growth and whether it is affecting vision.
A pterygium is a fleshy, usually triangular-shaped growth that extends from the conjunctiva—the thin tissue covering the white of the eye—onto the cornea, the clear front surface of the eye.
It is usually non-cancerous and may grow slowly over time. Exposure to ultraviolet (UV) light, wind and dust may contribute to its development. A pterygium can cause irritation and may affect vision if it alters the shape of the cornea or grows towards its centre
Small pterygia that are not causing problems may be monitored. Lubricating eye drops can help relieve dryness and irritation. UV-blocking sunglasses and a wide-brimmed hat can help protect the eyes outdoors.
Surgery may be recommended if the growth affects vision, continues to enlarge or causes persistent irritation despite treatment. An eye assessment can help determine whether surgery is appropriate. Pterygium can recur after removal, so follow-up remains important.
