Neovascular glaucoma has many etiologic causes, the vast majority resulting from retinal ischemia secondary to relatively common diseases such as central retinal vein occlusion, proliferative diabetic retinopathy and ocular ischemic syndrome (carotid stenosis). (Sivac-Callcott et al., 2001) Vascular endothelial growth factor is likely a major contributor to the development of angle and iris neovascularization. (Ferrara, 2004) Although panretinal photocoagulation and/or cryoablation are mainstays of conventional treatment for neovascular glaucoma, the delayed therapeutic effect of these interventions often results in the formation of peripheral anterior synechiae and permanent angle closure.
