AIM: To determine the safety and efficacy of intraoperative injection of mitomycin C (MMC) against conventional sponge-applied MMC during trabeculectomy. MATERIALS AND METHODS: This study was a retrospective, comparative case series. Thirty eyes with primary open-angle glaucoma underwent consecutive trabeculectomies with MMC injection (injection group), and thirty eyes with sponge-applied MMC were as controls (sponge group). Data were collected preoperatively and postoperatively at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year after surgery. Demographic data, applanation intraocular pressure (IOP), best-corrected visual acuity (VA), number of glaucoma medications, postoperative interventions, postoperative complications, and number of visits within 3 months were recorded. In order to stratify data, proportion of eyes achieving >30% IOP reduction from baseline with or without glaucoma medications was calculated and defined as surgical success. RESULTS: Mean IOP reduction at 1 year was significant in both the injection and sponge groups from baseline (46.8 and 37.8% respectively). The injection group had overall lower postoperative IOP and comparable complete treatment success, defined as achieving >30% IOP reduction without glaucoma medications (p = 0.941). The number of postoperative visits within 3 months and the proportion of eyes needing 5-fluorouracil (5-FU) intervention were significantly lower in the injection group (p = 0.03, p = 0.04 respectively). CONCLUSION: Injection of MMC was as safe and effective as sponge application with comparable estimated complete treatment success, less need for visits within 3 months, and 5-FU intervention. CLINICAL SIGNIFICANCE: Surgeons may consider intraopera-tive injection of MMC in appropriate patient cohorts given comparable safety and efficacy and several advantages over traditional sponge application. Further study in a prospective, larger, long-term manner is necessary to assess this modality.How to cite this article: Khouri AS, Huang G, Huang LY.
