Outcomes of neovascular glaucoma in eyes presenting with moderate to good visual potential

Purpose To compare the disease characteristics and treatment outcomes of patients with neovascular glaucoma (NVG) presenting with visual acuity (VA) 6/60 or better in two different health systems. Methods Retrospective chart review of consecutive patients with NVG who presented between January 2016 to January 2018 in 5 tertiary-centres in India and one eye-specialist centre in London (UK) was performed. The baseline characteristics, treatment provisions, and visual outcomes in the India and UK cohorts were compared. Results At presentation, 18% (83 of 451) and 22% (59 of 270) of patients with NVG had VA 6/60 or better in India and the UK cohorts, respectively. The aetiologies of NVG were similar with proliferative diabetic retinopathy being the most common cause (60.9%, India; 64.4%, UK; p = 0.38). Previous panretinal photocoagulation was more prevalent in the UK cohort compared to the India cohort (94.9% versus 66.3%, respectively; p
