PURPOSE: To assess the intraocular pressure (IOP)-lowering efficacy and the postoperative complication profile of viscocanalostomy versus trabeculectomy. PATIENTS AND METHODS: Sixty eyes of 60 patients with medically uncontrolled open-angle glaucoma were randomized either to the viscocanalostomy or to the trabeculectomy group of the trial. Viscocanalostomy was performed according to Stegmann's technique using high-molecular-weight sodium hyaluronate to fill the ostia of Schlemm's canal. For trabeculectomy, a modified Cairns-trabeculectomy was performed. Examinations were performed before surgery and postoperatively daily for one week. Follow-up visits were scheduled one, six, and 12 months after surgery. RESULTS: The mean (SD) preoperative IOP was 27.1 (7.1) mmHg for all patients enrolled. One day after surgery, mean (SD) IOP was 15.9 (5.2) for the trabeculectomy group (p < 0.001) and 15.7 (3.6) for the viscocanalostomy group (p < 0.001), respectively. The success rate, defined as an IOP lower than 22 mmHg without medication, was 56.7% in the trabeculectomy group and 30% in the viscocanalostomy group at 12 months' postoperatively (p = 0.041). The number of postoperative complications was lower in the viscocanalostomy group than in the trabeculectomy group. CONCLUSIONS: In eyes with open-angle glaucoma, viscocanalostomy is less effective in reducing IOP than standard filtering surgery. However, postoperative complications are more frequent after filtering surgery.
