A Pterygium is a wedge like growth on the white of the eye, which may become red and irritated. In severe cases, the growth may extend onto the clear cornea, and threaten vision.
Pterygiums occur due to irritation from long term sun damage and exposure to wind, glare and dust. Treatment involves minimising eye irritation with UV protection such as using sunglasses and hats, and eye drops to treat dry eye. In advanced cases, surgery is necessary to remove the pterygium.
