Central retinal artery occlusion (CRAO) is a devastating ocular emergency 
characterized by acute painless visual loss in the ipsilateral eye. We describe 
the case of acute non-arteritic CRAO associated fusiform internal 
carotid-ophthalmic artery aneurysm with intraluminal thrombus. Despite the 
rarity of this condition, we suggest that carotid-ophthalmic artery aneurysm 
should be included in the differential diagnosis of CRAO.
