Purpose: To identify the most common cause and the frequent stage of presentation in patients with
neovascular glaucoma.
Materials and Methods: The present study is a prospective observational study. 136 eyes of 109
patients having neovascular glaucoma in one eye or both the eyes were included in the study. All
patients underwent thorough ocular examination i.e., visual acuity, slit lamp bio-microscopy, intraocular
pressure (IOP) measurement by Goldmannapplanation tonometry, gonioscopy with Posner 4 mirror indirect
gonioscope and dilated fundus examination. Neovascularization of iris (NVI) was identified in an undilated
state, presence of any ectropionuveae, hyphema, anterior chamber reaction, pseudoexfoliative material,
keratic precipitates and other signs of uveitis were noted. The number of quadrants of the angle having
neovascularization was noted.
Results: The mean age was 57.59 12.6 years, 80.73% were males and 19.26% were females. Mean IOP
was 27.14 11.3 mm of Hg. 74 (54.4%) presented in rubeosisiridis stage, 38 (27.9%) in angle closure
stage and 24 (17.6%) in open angle stage. 89 (65.4%) had diabetic retinopathy in variable severity, 16
(11.7%) had uveitis and 14 (10.2%) had retinal vein occlusion. Mean IOP angle closure stage was found to
be 36.5316.259 mm of Hg which is significantly higher than the other two stages (P = 0.000)
Conclusion: In the present study, it was found that Proliferative diabetic retinopathy is the most common
cause and rubeosisiridis is the most common stage of presentation in NVG.
