Younger men with proliferative diabetic retinopathy, a higher baseline IOP, preoperative neovascularization in the anterior chamber angle and neovascular glaucoma in the fellow eye are at an increased risk of neovascular glaucoma after vitrectomy, a study found.
Neovascular glaucoma developed in 27 of 512 patients with proliferative diabetic retinopathy who underwent vitrectomy and were followed for a mean of 422 days, according to the retrospective study.
Kaplan-Meier survival analysis determined the probability of occurrence was 6% at 6 months, 7.1% at 12 months, and 8.7% at 24 and 36 months.
The investigators reported that significant risk determinants were male sex, younger age, increased IOP at baseline, preoperative neovascularization in the anterior chamber angle and current neovascular glaucoma in the fellow eye (P = .0032, P = .0237, P = .0335, P < .0001 and P = .0013, respectively).
