Beta radiation as an adjunct to low-risk trabeculectomy . PURPOSE To assess a single dose of intraoperative beta radiation used to enhance the success rate of trabeculectomy in a population of low-risk glaucoma patients in whom antimetabolites might not be indicated . METHODS A prospective randomized trial of 65 eyes was designed , with 31 eyes receiving 750 rads of intraoperative beta radiation ( group 1 ) , and 34 eyes receiving no supplementation ( group 2 ) . RESULTS Mean follow-up time was 24 months . Mean postoperative intraocular pressure was 12.2 mmHg in group 1 , and 13.7 mmHg in group 2 ( P = 0.16 ) . Mean decrease in intraocular pressure was 10.3 mmHg in group 1 , and 9.3 mmHg in group 2 ( P = 0.49 ) . The two groups were not significantly different in terms of surgical complications . CONCLUSION For this population of low-risk patients , there was no significant difference in outcome after applications of a single intraoperative dose of beta radiation .
