How does your treatment approach differ in patients with acute visual loss due to central retinal artery occlusion versus retinal vein occlusion?

Central retinal artery occlusion (CRAO), is an embolic event in most patients, where the source can be the heart or a plaque in the aorta or internal carotid artery. A prompt workup for the source is important. Central retinal vein occlusion is more often just the result of risk factors (such as diabetes) and a critical cause is often not found.

I agree. CRAO is a stroke equivalent and worked up as such. But in the acute setting, IV and even IA TPA/TNK are considerations albeit with limited data.
