Pterygium

Treatment: No treatment is required unless the pterygium begins to obstruct vision -- then it should be surgically removed. Protective glasses and a hat with a brim should be worn to prevent recurrences. Expectations (prognosis): Most pterygia cause no problem and need no treatment. If pterygium encroaches on the pupillary area of the cornea, results are usually good after removal. Complications: Text Continues Below Recurrence after removal. Calling your health care provider: People with pterygium should be seen by an ophthalmologist annually, so that encroachment on the pupil can be recognized and treated before interference with vision. Call for an appointment with your ophthalmologist if you have had a pterygium in the past and symptoms recur.
