Aim: To identify the most common cause and the frequent stage of presentation in patients with neovascular glaucoma. Material & Methods: The present study is a prospective observational study, 460 patients with Glaucoma of multiple type and of etiology underwent detail ophthalmological examination and 16 case those have been diagnosed as neovascular glaucoma (NVG) in one eye or both the eyes at Department of ophthalmology, Patna Medical College and Hospital, Patna, Bihar, India over a period of 13 months were included in the study, with prevalence of 3.5% of all glaucoma cases. Results: Most of the patients i.e., 11 (68.8%) presented in rubeosis iridis stage, 3 (18.75%) in open angle stage and 02 (12.5%) in angle closure stage. The Mean IOP in Angle closure stage was found significantly higher than the mean IOP in other two stages (P = 0.001). Conclusion: In the present study, it was found although prevalence of NVG is significantly low among cases of all glaucoma but the rising trend of Diabetic in population is of concern and this study also confirms that more than half of the cases of NVG were found with Proliferative diabetic retinopathy is the most common cause and rubeosis iridis stage was the commonest finding.
