Approximately 1 in 100 Australians will develop a pterygium. Excessive exposure to UV rays and prolonged irritation are known causes. Pterygiums are not dangerous and are a overgrowth of tissue that very slowly moves from the conjunctiva towards the centre of the eye. They usually begin on the nasal side of the eye. In most cases the only action required is to wear sunglasses and the occasional use of topical lubricants. If the pterygium advances towards the centre of the eye it can affect vision and then needs to be removed. This involves a simple surgical procedure. Optometrists are trained in the detection and management of pterygiums.
