PTERYGIUM WHAT IS PTERYGIUM? A pterygium is a wing-shaped extension of thickened tissue on the surface (conjunctiva) of the white of the eye, which grows onto the adjacent cornea (the window into the eye). Pterygia are benign growths (not cancers), which can continue to grow across the eye and eventually seriously affect sight. It is a fairly common condition. It may occur in one or both eyes. Pterygia generally start in susceptible young adults, and gradually increase in size over the years. In some people, growth may cease after a period, and particularly in the elderly, they may become inactive. WHAT ARE THE SYMPTOMS OF PTERYGIUM? Symptoms include recurrent redness, a feeling of irritation, and watering, although some people may not have any symptoms. If the pterygium grows too far across the cornea, it may affect sight. WHAT ARE THE TREATMENT OPTIONS? Protection from the elements (wind, dust, sea water, sunlight etc) is important; particularly the wearing of a hat and UV filtering sun-glasses, when outdoors. This will reduce symptoms, and prevent progression. It will also reduce the risk of recurrence following removal. In addition, for small pterygia which do not seem to be growing and for which surgery is not necessary, lubricant drops, and occasional decongestant drops that reduce the redness, may be prescribed. If the pterygium appears to be growing, removal is necessary before it gets to the point where it starts to affect vision. If it is left to grow too far across the cornea, residual scarring means that even after excision vision will not return to normal.
