To investigate the prognostic factors for neovascular glaucoma after vitrectomy in eyes with proliferative diabetic retinopathy. METHODS: In the present study we retrospectively reviewed intraindividual and interocular differences in 14 patients (28 eyes) who underwent pars plana vitrectomy for proliferative retinopathy with vitreous hemorrhage and having only 1 eye neovascular glaucoma. The patients underwent vitrectomy between March 2008 and July 2014 at Maryknoll Hospital. The patient clinical data on preoperative, intraoperative and postoperative factors were compared. Statistical analysis was performed using the Wilcoxon matched-pairs signed-rank (Mann-Whitney) test and chi-square test to evaluate the significance of differences within the patient groups. RESULTS: The decrease of photopic b-wave amplitudes on the preoperative electroretinogram significantly correlated with the development of neovascular glaucoma after vitrectomy for proliferative retinopathy with vitreous hemorrhage (p > 0.05). CONCLUSIONS: Based on the results from the present study, decreased photopic b-wave amplitudes on preoperative electroretinogram is an effective prognostic factor for the development of neovascular glaucoma after vitrectomy for proliferative retinopathy with vitreous hemorrhage.
