Prevention of Retinal Non-perfusion in Central Retinal Vein Occlusion by Hydroxycarbamide Treatment.

The central retinal vein occlusion (CRVO) is a major cause of ocular morbidity, depending in particular on the occurrence and extent of retinal ischemia by capillary occlusion. There is no effective systemic treatment of this condition. An increase in the adhesion of erythrocytes to vascular endothelium was observed for patients with CRVO, correlated with overexpression of membrane phosphatidylserine
