THE PRESENT study has three objectives: (1) to evaluate the usefulness of beta-irradiation from a radium D applicator in the therapy (a) of primary pterygium and (b) of recurrent pterygium; (2) to find an effectual and useful dosage schedule in this therapy, and (3) to compare the effectiveness of radium D with that of surgery alone and with that of combined surgery and x-irradiation in the treatment of primary and recurrent pterygium.
MATERIAL AND METHODS
Included in this study were 77 patients, with a total of 85 eyes with pterygium. Thirty-six patients, and 42 eyes, were treated surgically. Forty-one patients, and 43 eyes, were treated with beta-irradiation. Since some patients in the surgical group had recurrences, several were treated for recurrent pterygium. This does not mean, however, that several of the patients with recurrent pterygium did not have one or more secondary surgical procedures in an attempt to eradicate the
