A pterygium is a fleshy growth of the conjunctiva and one in every 100 Australians develops a pterygium. One or both eyes may be affected.
UV exposure from the sun and a person’s genetics are two main risk factors.
A pterygium is usually asymptomatic but it can cause irritation to the eye as it grows larger. Lubricating eye drops can be used to reduce irritation.
If untreated, a pterygium may grow across the cornea and affect vision.
A pterygium can be usually removed via surgery. There is a small chance of recurrence after surgery.
