Central retinal vein occlusion, also known as CRVO, is a condition in which the main vein that drains blood from the retina closes off partially or completely. This can cause blurred vision and other problems with the eye.
The pathogenesis of CRVO is believed to follow the principles of Virchow’s triad for thrombogenesis, involving vessel damage, stasis and hypercoagulability. The central retinal vein and artery share a common adventitial sheath at arteriovenous crossings posterior to the lamina cribrosa so that atherosclerotic changes of the artery may compress the vein and precipitate CRVO. So, the pathogenesis of CRVO is related critically to the changes in the central retinal artery
