Abstract

Central retinal artery occlusion (CRAO) is the ocular analog of ischemic stroke, causing sudden visual loss. The most common cause of CRAO is embolism due to atherosclerosis of the carotid artery. CRAO resulting from paradoxical embolism, such as a patent foramen ovale (PFO), is uncommon. It is also rare for CRAO to present with neurological symptoms other than visual loss. We report a case of transient oculomotor nerve palsy in a patient with CRAO caused by PFO.
