Quick answer
What is Pterygium?
A pterygium is a fleshy, wing-shaped growth of tissue on the surface of the eye, usually starting on the white of the eye nearest the nose and sometimes extending onto the clear cornea. It is thought to be linked to long-term exposure to ultraviolet (UV) light, wind and dust, which is why it is more common in people who spend a lot of time outdoors in sunny, windy environments (hence the nickname "surfer's eye").
- How it is treated: Management depends on symptoms and growth.
- Self-care: Protecting the eyes from UV light with wraparound sunglasses and a hat, avoiding wind and dust where possible, and using lubricating drops for dryness all help reduce irritation and slow the growth of a pterygium.
- When to seek help: See an optician or GP about a growth on the surface of the eye, especially if it is growing, affecting vision, or causing persistent irritation, so it can be assessed and monitored and treatment discussed if needed.
What it is
A pterygium is a fleshy, wing-shaped growth of tissue on the surface of the eye, usually starting on the white of the eye nearest the nose and sometimes extending onto the clear cornea. It is thought to be linked to long-term exposure to ultraviolet (UV) light, wind and dust, which is why it is more common in people who spend a lot of time outdoors in sunny, windy environments (hence the nickname "surfer's eye"). It is not a cancer. Many pterygia cause few problems beyond appearance, but they can cause redness, irritation, a gritty feeling and dryness, and if one grows across the cornea it can distort vision (causing astigmatism) or, rarely, affect sight. It tends to grow slowly, and growth can be triggered by ongoing UV exposure and dryness.
How it is treated
Management depends on symptoms and growth. Many pterygia need no treatment beyond protecting the eyes and relieving irritation — lubricating (artificial tear) drops help dryness and grittiness, and, if inflamed, short courses of anti-inflammatory drops may be used. Protecting the eyes from UV light with wraparound sunglasses, and from wind and dust, helps reduce irritation and slow growth. If a pterygium grows enough to threaten or affect vision, causes persistent significant symptoms, or is very bothersome cosmetically, it can be removed surgically, though pterygia can sometimes recur after surgery. Care is usually guided by an optician or eye specialist, who monitors growth and advises on when treatment is worthwhile.

Answers
Pterygium: frequently asked questions
Is a pterygium cancer?
No — a pterygium is a non-cancerous fleshy growth on the surface of the eye, linked to long-term sun, wind and dust exposure. It can, however, grow across the cornea and affect vision, so it is monitored.
Does a pterygium need to be removed?
Often not — many just need eye protection and lubricating drops. Removal is considered if it grows enough to affect vision, causes persistent significant symptoms, or is very bothersome, though it can sometimes recur after surgery.
