Pterygium

Exposure to sunlight is the most common cause of pterygia and as a result they  are very common in Australia. People at most risk are those who spend a lot of time outdoors, such as farmers, surfers and keen golfers. 

In most cases, pterygia cause chronic dryness and discomfort. They also frequently become red and inflammed. 

They can affect the sight by causing astigmatism, or, if they are large enough, by blocking the light from entering the eye.

The best way to make your eye comfortable is to use plenty of lubricants. It is also important to protect your eyes with sunglasses.

Occasionally prescription eye drops may be needed if the eye is very inflammed, although this is not recommended for long-term treatment.
