Abstract
Eight eyes with central retinal vein occlusion one eye with old central retinal artery occlusion complicated by rubeosis iridis or increased intraocular pressure, or both; and one eye with diabetic retinopathy and rubeosis iridis were treated by retinal panphotocoagulation. Vision did not improve but intraocular pressure was lower and iris neovascularisation regressed in most cases, supporting the hypothesis that retinal hypoxia is a cause of iris neovascularisation and suggesting that retinal panphotocoagulation has a potential prophylactic and therapeutic role in rubeosis iridis and early neovascular glaucoma.
