Posterior Segment Neovascularization in Retinal Vein Occlusion,clusion led to the hypothesis of a diffusible factor arising from ischemic retina as the cause of the complication.3,26 Vascular endothelial growth factor (VEGF) was subsequently discovered to be that mediator (see Chap. 2).28 In this chapter, we focus on the clinical manifestations of PSNV in retin

Anterior Segment Neovascularization in Retinal Vein Occlusion, levels of vascular endothelial growth factor (VEGF). It differs in that it generally requires higher levels of VEGF to induce anterior segment neovascularization than to induce posterior segment neovascularization. Because levels of VEGF correlate with area of retinal ischemia, it is rare for anter

Treatment of Retinal Vein Occlusions,central retinal vein occlusion (CRVO)) have been tried and discarded as evidence accumulates of inefficacy or too many adverse events. These treatments are covered, mainly for historical purposes, in Chap. 15. On the other hand, some treatments are not adopted because of impracticality or cost-benef

A review of the failures and an analysis of the reasons may be helpful for future attempts at devising more successful therapy than we currently have. Reasons for failure range widely: treatment is based on an erroneous conception of pathogenesis, too many complication
