Effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage

Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P 0.05). The postoperative complications mainly included fibrosis exudates in anterior chamber (7 eyes), intraocular pressure elevation 1-2 weeks after the operation (2 eyes), and postoperative suprachoroid-cavity hemorrhage (2 eyes). Conclusion Vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy may be effective procedures for some cases of neovascular glaucoma combined with vitreous hemorrhage.
