The use of postoperative beta radiation in the treatment of pterygia

Abstract

Results of 483 cases of pterygia treated with surgery and prophylactic postoperatory beta therapy are discussed. Distribution by age and sex show the predominant age range to be between 20 to 50 years with an almost equal proportion of males and females. The postoperative dose administrated was 2800 rads in four to five days overall time, with a recurrence rate of 4.32%. Of this group of recurrent cases, only one patient received the first irradiation treatment immediately after surgery; the rest were treated 24 hours after being operated. We have found no undesirable side effects or damage produced by beta radiation.
