PURPOSE: To compare viscocanalostomy, a nonpenetrating procedure for glaucoma treatment, with trabeculectomy. DESIGN: Randomized controlled trial. PARTICIPANTS: Twenty white subjects (20 eyes) with open-angle glaucoma with no history of surgery were enrolled. METHODS: Ten subjects were randomly assigned to viscocanalostomy according to Stegmann's technique and ten subjects to a modified Cairns trabeculectomy. A complete ophthalmological examination was performed the day before surgery and postoperatively. Further visits were scheduled monthly for six to eight months after surgery. MAIN OUTCOME MEASURES: Success was defined as intraocular pressure (IOP) between 7 and 20 mmHg, with no medication. RESULTS: After a mean follow-up of six months (range, 6-8 months), success was obtained in five of ten cases in the trabeculectomy group and in no case in the viscocanalostomy group. With Kaplan-Meier's method, subjects with viscocanalostomy showed shorter postoperative IOP-reduction periods than subjects undergoing trabeculectomy. CONCLUSIONS: According to the results of this short-term study, trabeculectomy was more effective than viscocanalostomy in lowering IOP in glaucomatous eyes of white patients.
