BACKGROUND AND OBJECTIVE: To compare the safety and efficacy of fornix-based trabeculectomy with corneal valve to traditional limbal-based trabeculectomy with mitomycin C (MMC) in eyes with open-angle glaucoma. PATIENTS AND METHODS: In this retrospective, nonrandomized, comparative study, 42 eyes that underwent limbal-based trabeculectomy with MMC were compared with 32 eyes with fornix-based trabeculectomy with corneal valve with MMC. Success was defined as final intraocular pressure (IOP) of at least 20% less than preoperative IOP and between 5 and 22 mmHg. RESULTS: The preoperative and postoperative mean IOPs were 23.5 ± 12.2 and 11.5 &plusm; 5.3 mmHg, respectively, in the limbal-based group and 24.8 &plusm; 11.1 and 11.7 ± 2.5 mmHg, respectively, in the fornix-based group (P < .001 and P = .85, respectively). The fornix-based group had significantly less hypotony (3% vs 21%, P < .05). CONCLUSIONS: Fornix-based corneal valve trabeculectomy with posterior placement of MMC sponges provides IOP control comparable to limbal-based traditional trabeculectomy, with decreased incidence of hypotony.
