Small growths usually on the nasal side of the white part of the eye are common in this latitude around the world. When these growths advance onto the dome or cornea of the eye, they are called pterygiums. Pterygium surgery is frequently performed at Schuster Eye Center. These growths, if not removed expeditiously, can eventually cover the pupil and lead to permanent visual loss. Pterygiums tend to run in families. Pterygiums are more common in people with high exposure to sunlight, wind, and dust. At Schuster Eye Center, removal of pterygiums with proper techniques, post-operative medications, and sometimes x-ray treatments ensure that, although not always possible, the growths have a lesser chance of recurring. Schuster Eye Center performs two to four pterygium surgeries per week.
