Effect of beta radiation on success of glaucoma drainage surgery in South Africa: randomised controlled trial.

ABSTRACT:

Objective

To evaluate whether beta radiation may offer a practical method of improving surgical success for glaucoma drainage surgery in South Africa.

Design

Double blind, randomised controlled trial.

Setting

Three public hospitals in South Africa.

Participants

450 black Africans with primary glaucoma.

Interventions

Trabeculectomy with 1000 cGy beta radiation or standard trabeculectomy without beta radiation (placebo).

Main outcome measures

Primary outcome measure was surgical failure within 12 months (intraocular pressure > 21 mm Hg while receiving no treatment for ocular hypotension). Secondary outcomes were visual acuity, surgical reintervention for cataract, and intraoperative and postoperative complications.

Results

320 people were rec
