Abstrakt:	Purpose: Evaluate the intraocular pressure (IOP) control in combined Ahmed Glaucoma Valve (AGV) implantation and trabeculectomy revision with adjunctive antimetabolite compared with AGV alone in patients who failed prior trabeculectomy. Methods: Consecutive cases of combined AGV implantation and trabeculectomy revision with adjunctive antimetabolite (combined group) after January 3, 2014 were case-matched to cases of AGV implantation alone (AGV-alone group) before January 3, 2014. Primary outcome measures were qualified success with stratified IOP targets based on criteria: (A) IOP≤18 mm Hg and 20% IOP reduction; (B) IOP≤15 mm Hg and 25% IOP reduction; (C) IOP≤12 mm Hg and 30% IOP reduction, and hypertensive phase (HP) rate. Secondary outcome measures were 1-year postoperative IOP and number of glaucoma medications and complications. Results: Twenty eyes (20 patients) in each group were included. Cumulative success for combined group and AGV-alone group at 1-year were: 74.0% versus 59.2% (criterion A, P=0.221), 61.9% versus 49.5% (B, P=0.183), and 54.2% versus 30.0% (C, P=0.033), respectively. In total, 50% (10 eyes) in the AGV-alone group developed HP compared with 15% (3 eyes) in the combined group (P=0.041). At 1-year follow-up, combined group had statistically significantly lower IOP than AGV-alone group (10.1±4.4, 13.3±2.9 mm Hg, respectively; P=0.028). There were no cases of bleb-related infections, choroidal effusion or hemorrhage, persistent hypotony, or hypotony maculopathy in either group. Conclusions: Combining AGV implantation with trabeculectomy revision with antimetabolite was associated with better tonometric success compared with AGV implantation alone in patients with previously failed trabeculectomy, particularly when a low IOP target (≤12 mm Hg) is required. Revised trabeculectomy may provide complimentary outflow facility to AGV.
