A pterygium (ter-IH-jee-um) is an abnormal growth of tissue that starts along the edge of the eye and spreads to the cornea, the eye’s clear, protective covering. Pterygiums are common in people who live in warm, sunny, climates and are generally harmless unless they grow to the point that they interfere with vision. An optometrist or ophthalmologist (off-thal-MOLL-oh-jist) can perform a simple, outpatient surgical procedure to remove the tissue. An incision is made in the cornea around the pterygium, then the growth is cut free and removed. A few, fine sutures are inserted in the eye until the incision heals which can take from one to three weeks. Antibiotic eye medication may be prescribed to ward off infection, and a pain reliever may be needed to help relieve any discomfort. The doctor may recommend avoiding vigorous activities for a few weeks following surgery, but in the majority of cases, a normal schedule can be resumed shortly after the surgery. If you notice any type of abnormal growth in your eye, see an eye care specialist for a complete eye examination. This information is not intended to be a substitute for diagnosis or medical care.
