Abstract |
PURPOSE To evaluate the efficacy of intravitreal bevacizumab and subsequent trabeculectomy with mitomycin C (MMC) for neovascular glaucoma (NVG) in eyes that underwent previous 23-gauge transconjunctival sutureless vitrectomy (TSV). METHODS: This was a retrospective, comparative, and consecutive case series study. We reviewed the medical records of patients with NVG who underwent trabeculectomy with MMC after intravitreal bevacizumab (1.25 mg/0.05 mL) injection and compared the surgical outcomes according to 23-gauge TSV history. Surgical success was defined as an intraocular pressure (IOP) of ≥6 mm Hg and ≤21 mm Hg without additional glaucoma surgery or loss of light perception. The main outcome measures were postoperative IOP control, visual acuity, and complications. RESULTS: A total of 27 patients (27 eyes) were included; 12 patients with 23-gauge TSV history (TSV group) and 15 patients without vitrectomy history (nonvitrectomized group). The cumulative probability of success after trabeculectomy with MMC was 82.5% and 73.3% after one year for the TSV group and the nonvitrectomized group, respectively (p = 0.523). Mean IOP decreased from 37.3 ± 9.0 mm Hg preoperatively to 12.8 ± 6.2 mmHg at the final visit in the TSV group (p = 0.002). Mean IOP decreased from 40.3 ± 9.7 mm Hg preoperatively to 17.8 ± 11.7 mm Hg at the final visit in the nonvitrectomized group (p = 0.001). Preoperative and final IOP were not significantly different between the two groups. Complications were comparable between the groups. CONCLUSIONS: Intravitreal bevacizumab injection and subsequent trabeculectomy with MMC is an effective method for controlling IOP in patients with NVG associated with sutureless vitrectomy. |
