NEOVASCULAR GLAUCOMA: AS A MANIFESTATION OF DIABETES MELLITUS (LITERATURE REVIEW)

Neovascular glaucoma (NVG) is a form of secondary glaucoma and is defined by the presence of neovascularization on the iris and the growth of fibrovascular tissue in the anterior chamber and typically associated with poor visual prognosis. The growth of new blood vessels in the iris and iridocorneal angle can block the drainage of aqueous humor, causing a rise in intraocular pressure (IOP). Proliferative diabetic retinopathy (PDR) and central retinal vein occlusion are the most common causes of posterior segment ischemia. One of the main reasons for NVG is PDR. The prevalence rate of NVG is rising due to the increasing diabetes population. In order to prevent neovascularization and preserve vision, early diagnosis and intensive treatment are crucial. The purpose of this review is to provide an overview of NVG caused by diabetic retinopathy (DR), including the epidemiology, pathogenesis, clinical manifestations, diagnosis and management, to offer a more complete understanding.
