Abstract

To study the effect of beta ray irradiation in preventing the recurrence of pterygium following surgical removal, clinical observation was made on 483 eyes in 447 patients who received. beta ray irradiation by 90Sr applicator (SIA-2) after operation for pterygium. Irradiation was given in doses of 360 rads 4 times with 2 days interval from immediately afteroperation. The results were as the followings: 1. Most cases were 31-40 years of age (158 eyes, 32.7% ); next, 41~50 years of age (112 eyes, 23.2%); the least, over 71 years of age (5 eyes, 1.0%). 2. All 483 cases consisted of 292 eyes (60.5%) in female and 191 eyes (39.5%) in male, but there was no significant difference in the site of the disease; right eyes, 257 eyes (53.2%) and left eyes (226 eyes)(46.8%). 3. Of all cases. 460 eyes (95.2%) was primary pterygium and 23 eyes (4.8%) recurrent pterygium. 4. Over all incidence of recurrence was 1.9% (9 eyes) of which primary pterygium occupied 1.7% (8 eyes) and recurrent type 0.2% (1 eye). 5. Of the patients with bilateral involvement, 3 cases showed unilateral recurrence.
