A non enhanced CT scan of the brain is unremarkable.
In contrast images, there is a lack of visualization of the right ophthalmic artery within the optic canal and the globe, suggesting occlusion, while the left ophthalmic artery is patent and visualized.
Case Discussion
The ophthalmic artery is a branch of the C6 segment of the internal carotid artery, and embolic occlusion most commonly originates from ipsilateral carotid artery plaque showering or from a cardiac origin.
Arterial occlusion leads to retinal infarction and a sudden, painless loss of vision that is usually irreversible, as seen in this patient.
