Neovascular Glaucoma: Etiology and Staging

The goal of this study was to determine the most prevalent aetiology of neovascular glaucoma and the most common stage of the patient’s presentation.

The current study employs an observational prospective design. A total of 136 eyeballs from 109 patients with neovascular glaucoma in one or both eyes were included in the study. All patients had visual acuity testing, slit lamp biomicroscopy, intraocular pressure (IOP) measurement with Goldmann applanation tonometry, gonioscopy with a Posner 4 mirror indirect gonioscope, and a dilated fundus examination. NVI was defined as a tuft of new vessels on the iris, mostly near the pupillary margin in an undilated state, the presence of any ectropion uveae, hyphema, anterior chamber reaction, pseudoexfoliative material, keratic precipitates, and other uveitis symptoms. The angle’s number of neovascularized quadrants was counted.

The average age was 58.1813 years, with 80.73 percent of men and 19.26% of women participating. IOP was 27.14 11.3 mm Hg on average. The rubeosis iridis stage was represented by 74 (54.4%), the angle closure stage by 38 (27.9%), and the open angle stage was represented by 24. (17.6 percent ). 89 (65.4%) of the subjects had diabetic retinopathy of various degrees of severity, whereas 16 (11.7%) had uveitis and 14 (10.2%) had retinal vein occlusion. The average IOP angle closure stage was 36.5316.259 mm Hg, which was significantly higher than the other two (P = 0.000).

According to the findings of this study, proliferative diabetic retinopathy is the most common cause of NVG, and rubeosis iridis is the most common stage of presentation.
