Description
Summary:Neovascular glaucoma (NVG) is a cause of blindness in patients with proliferative diabetic retinopathy (PDR) and remains a clinical challenge. It results from vascular endothelial growth factor (VEGF) expression, which occurs in cases of severe retinal ischemia. Early detection and immediate comprehensive management, including early surgical intervention, are essential to maintain good intraocular pressure (IOP) control and achieve the best visual outcome, as presented in this case. A 42-year-old male patient with bilateral NVG secondary to PDR received complex management with early Ahmed valve implantation surgery, followed by pan-retinal photocoagulation (PRP) and intravitreal bevacizumab injection. After 22 months of treatment and follow-up, we could achieve the best visual outcome for the patient. Early surgical intervention for uncontrolled NVG with a glaucoma filtration device combined with intravitreal anti-VEGF injections and adequate PRP showed beneficial effects in the IOP control with rapid resolution of iris neovascularization, thus achieving the best visual function.
