新生血管性青光眼起因于视网膜缺血,最常在视网膜静脉阻塞和增生性糖尿病性视网膜病变之后。由于房角内出现新生血管和纤维化,继之因纤维组织收缩致使房角闭塞而发病。全视网膜光凝术可防止新生血管的形成,甚可在早期形成纤维组织之前消除之。但若房角一经为纤维组织所阻塞,全视网膜光凝术将无可能 Neovascular glaucoma results from retinal ischemia, most often after retinal vein occlusion and proliferative diabetic retinopathy. Due to the emergence of angiogenesis and fibrosis in the corner, followed by contraction of the fibrous tissue resulting in the closure of the angle of the disease. Retinal photocoagulation prevents the formation of neovascularization and can be eliminated even before early formation of fibrous tissue. However, if the angle is blocked by fibrous tissue, panretinal photocoagulation will be impossible
