To investigate the rate and risk factors for neovascular glaucoma (NVG) after vitrectomy in proliferative diabetic retinopathy (PDR).Five hundred twelve patients (512 eyes) with PDR who underwent between January 1, 2003 June 30, 2009 at Kumamoto University Hospital, Japan, were retrospectively evaluated. Postoperative NVG was defined as neovascularization anterior segment intraocular pressure (IOP) ≥ 22 mm Hg vitrectomy. Kaplan-Meier survival analysis applied to calculate of Risk identified by multivariable using Cox proportional hazards model.The mean follow-up period 422 days. Twenty-seven 512 (5.3%) developed postoperative The probability occurrence 6 12 months 6.0% 7.1%, respectively. Male sex [relative (RR)=4.247; P=0.0032), younger age (RR=0.956/y; P=0.0237), higher baseline IOP (RR=1.203/mm Hg; P=0.0335), preoperative chamber angle (RR=8.899; P<0.0001), presence fellow eye (RR=5.355; P=0.0013) significant NVG.The frequency eyes within 1 year estimated 7.1%. is independently associated male sex, age, IOP, angle, eye.
