To identify the most common cause and the stage of presentation in patients with neovascular glaucoma: A prospective observational study

Abstract

Aim: To identify the most common cause and the frequent stage of presentation in patients with neovascular glaucoma. Materials and Methods: The present prospective observational study was conducted in the Department of Ophthalmology, B.R. Singh Hospital Kolkata, WB,  India, from April 2018 to Jan 2020. Total 150 eyes of 120 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.

Results: The present study was conducted in 150 eyes of 120 patients out of which 110 patients had either eye involvement and 20 patients had both eyes involvement. All Patients were aged between 12-74 years with a mean of 55.47 ± 13.4 years. Out of 120 patients, 90 (75%) were males and 30 (25%) were females.The range of intraocular pressure (IOP) was 2-74 mm of Hg with mean of 28.11 ± 10.2 mm of Hg.84 (56%) presented in rubeosisiridis stage, 44 (29.33%) in angle closure stage and 22 (14.67%) in open angle stage.Out of 150 eyes, 90 (60%) had diabetic retinopathy in variable severity, 21 (14%) had inflammatory etiology, 17 (11.33%) had retinal vein occlusion and 17 (11.33%) had glaucoma (PXG and absolute glaucoma.Mean IOP angle closure stage was found to be 35.87±15.277 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.
