- Abstract
Neovascular glaucoma (NVG) is a severe form of secondary glaucoma that is characterized by the growth of abnormal blood vessels over the iris and within the iridocorneal angle. This condition is primarily caused by retinal ischemia, which is commonly associated with conditions such as central retinal vein occlusion and diabetic retinopathy. The management of NVG focuses on reducing retinal ischemia through treatments such as panretinal photocoagulation and anti-VEGF injections. Diabetic retinopathy, the most common cause of reversible blindness, is characterized by damage to the blood vessels in the retina due to uncontrolled diabetes. It manifests in two primary forms: nonproliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). NPDR is characterized by microaneurysms, hemorrhages, hard exudates, and cotton wool spots, while PDR is characterized by neovascularization. The prevalence of diabetic retinopathy is high, particularly in individuals with type 1 diabetes. NVG can be triggered by various ocular and systemic conditions, including retinal venous obstructive disease, diabetic retinopathy, and carotid artery obstructive disease. The pathophysiology of NVG involves the growth of new blood vessels in the retina due to inadequate blood supply, leading to increased intraocular pressure. The signs and symptoms of NVG include redness, pain, and vision
