Retinal branch vein occlusion with retinal neovascularisation – http://id.who.int/icd/entity/766672706

This is a common retinal vascular disease of the elderly. It is caused by the occlusion of one of the branches of central retinal vein. This diagnosis is with the formation of functional microvascular networks with red blood cell perfusion. Neovascularization differs from angiogenesis in that angiogenesis is mainly characterised by the protrusion and outgrowth of capillary buds and sprouts from pre-existing blood vessels.
