PURPOSE: This study aimed to investigate the safety and efficacy of trabeculectomy with intraoperative mitomycin C (MMC) in the management of eyes with neovascular glaucoma (NVG). METHODS: Fifteen eyes of 14 patients with NVG were included in the study. NVG was secondary to central retinal vein occlusion (three eyes), hemiretinal vein occlusion (two eyes), proliferative diabetic retinopathy (eight eyes), branch retinal vein occlusion (one eye), and idiopathic (one eye). Preoperative retinal ablation was performed in eyes with evidence of posterior segment ischemia. Following this, all eyes underwent trabeculectomy with intraoperative MMC (0.4 mg/ml for three minutes). Clinical outcome assessment included visual acuity, intraocular pressure (IOP), bleb appearance, identification of complications and antiglaucoma medications required to control IOP. RESULTS: The mean IOP decreased from 38.6 ± 12.9 mmHg (range, 15-64 mmHg) to 17.4 ± 9.33 mmHg (range, 4-34 mmHg) (p = 0.001). Preoperative visual acuity ranged from light perception to 6/9 in the affected eye. Thirteen (86.6%) of 15 eyes improved vision or retained preoperative vision, one (6.7%) eye lost light perception, and one (6.7%) eye developed tractional retinal detachment two years after trabeculectomy. Ten (66.7%) of 15 eyes were classified as surgical success with a mean follow-up of 28.6 ± 26.3 months (range, 2-82 months). None of the patients developed choroidal hemorrhage, hypotony maculopathy, late onset bleb leak or endophthalmitis. CONCLUSION: Trabeculectomy with intraoperative MMC is a good treatment modality in the management of eyes with NVG.
