OBJECTIVES: To study the efficacy and safety of different treatments for diabetic neovascular glaucoma (NVG). We additionally attempt to determine if the presence of NVG could be a predictor of cardiovascular disease or death. METHOD: This is a retrospective, observational cohort study including patients diagnosed with diabetic NVG from 2006 to 2016 at the Hospital Clínico Universitario de Valladolid (Spain). Extracted data included clinical characteristics of the patients, glycated haemoglobin levels, and ocular treatment. Visual acuity (VA), intraocular pressure (IOP), cardiovascular events, and deaths were registered. RESULTS: 30 eyes from 23 patients were followed for a mean of 4.48 years (SD = 2.82 years). The IOP-lowering intervention groups were: Ahmed implant (11 eyes), laser cyclo-photocoagulation (CPC; 6 eyes), both (4 eyes), or none (9 eyes). IOP success was achieved in 100% of the eyes with Ahmed and/or laser CPC and in 44.4% of the eyes with no IOP-lowering procedure (p= 0.002). Most eyes with Ahmed implant (with or without CPC) maintained or improved their VA (100 and 63.6%, respectively). 33.3% of the eyes with laser CPC and 25% of those with no IOP-lowering intervention maintained or improved their VA (p = 0.028). Hypotony was the only adverse effect (after laser CPC). No statistically significant difference could be established between low VA (finger count or worse), poor IOP control, or bad metabolic control and mortality or cardiovascular event (p > 0.05), however, the four patients who died had poor VA at the time of NVG diagnosis. CONCLUSIONS: Ahmed implant surgery is a safe and effective treatment option for diabetic NVG. Medical treatment alone is not the best option for most cases. Advanced NVG could be an indicator of higher mortality risk in diabetic patients.
