A pterygium is a triangular, pinkish growth on the white of the eye, usually on the side nearest the nose. It is common in sunny, dusty places and among people who work outdoors.
Symptoms
- A visible growth on the eye
- Redness, grittiness or a feeling of something in the eye
- Dryness and irritation
- Blurred vision if it grows over the centre of the cornea or causes astigmatism
Managing it
- Wear UV-protective sunglasses outdoors
- Use a hat and avoid dusty, windy exposure where possible
- Lubricating drops for irritation
- Regular checks to monitor its size
When surgery helps
If a pterygium affects vision, keeps growing or causes persistent discomfort, it can be removed. Surgeons usually cover the area with a small graft of your own tissue to reduce the chance of it returning.
See our guide to sunglasses and UV protection.
Frequently asked questions
Is pterygium cancer?
No. It is a benign growth. Your doctor will check that the growth is typical.
Can it come back after surgery?
It can recur, which is why grafting techniques and sun protection after surgery are important.
