Scheme of central retinal vein occlusion (CRVO) and the association with glaucoma. Pre-existing glaucoma can be a risk factor and contribute to the onset of CRVO (broken arrow); after the attack of CRVO, and especially ischemic CRVO, patients develop neovascular glaucoma (NVG) at a higher frequency due to elevated vascular endothelial growth factor (VEGF) and formation of neovascularization in the angle of the eye (solid thick arrow). Or less often, patients develop angle-closure glaucoma (ACG) due to a shallow anterior chamber as demonstrated in this study (solid thin arrow)
