Postoperative beta irradiation in the treatment of pterygium

High recurrence rates are reported after surgical treatment of pterygia. With the use of beta irradiation, the recurrence rate drops dramatically. This paper describes technic and dosage used in a group of patients receiving postoperative beta irradiation. Two thirds of these patients, however, had at least two surgical procedures. A recurrence rate of 3.5% was observed, with no apparent morbidity.
