Anti-VEGF drugs in the treatment of neovascular glaucoma
Neovascular glaucoma (NVG) is the most frequently occurring type of secondary glaucoma characterized by significant decrease in visual functions. Its pathogenesis consists mainly of ischemia of the posterior segment, which is often secondary to proliferative diabetic retinopathy or ischemic central retinal vein occlusion. Development of neovascularization in the eye is associated with processes that change homeostatic balance between proangiogenic (vascular endothelial growth factor (VEGF)) and antiangiogenic (pigment epithelium-derived factor (PEDF)) factors. The aim of the therapy is to reduce the production of aqueous humour. Application of antiangiogenic preparations in patients with NVG as adjuvant therapy is the method of choice for both prevention and treatment of the disease. The article reviews literature on current possibilities of using anti-VEGF drugs in the treatment of NVG.
