PURPOSE: To investigate the efficacy of intraoperative sub-Tenon injection of triamcinolone acetonide (TA) in increasing the success rate of trabeculectomy for the treatment of secondary glaucoma. DESIGN: Prospective randomized controlled clinical trial. METHODS:Fifty-three consecutive eyes scheduled for trabeculectomy were randomly allocated in an institutional setting. In the study group (n = 26), TA was injected in the sub-Tenon at the conclusion of the surgery. In the control group (n = 27) surgery was completed without TA injection. Surgical success was defined as a complete success if the intraocular pressure (IOP) was 21 mm Hg or less with an IOP reduction of greater than or equal to 20% without any antiglaucoma medication. Success rates in both groups were compared using Kaplan-Meier survival curves and the log-rank test. The morphologic characteristics of the filtering blebs were evaluated using the Indiana Bleb Appearance Grading Scale. RESULTS:Fifty-three eyes completed the study (26 in the study group and 27 in the control group), with a follow-up of 12 months. Complete success rates were 65.4% for the study group and 63.0% for the control group (P = .77) at 12 months. The morphologic characteristics of the filtering blebs and postoperative complications were similar in the study and the control eyes (P > .40). IOP measurements in both groups were similar at all visits (P > .05). CONCLUSIONS:Trabeculectomy with intraoperative sub-Tenon injection of TA for the treatment of secondary glaucoma neither increased the intermediate-term success rate nor decreased postoperative complications.
