Embryology and Variations of the Ophthalmic Artery

Unexpected Bilateral Emergence of the Ophthalmic Arteries from the Cavernous Segment of the ICA in a Patient with Multiple Intracranial Aneurysms

“…A bilateral cavernous carotid origin is uncommon. During embryological development, when there is persistence of the primitive ventral ophthalmic artery with regression of the primitive dorsal ophthalmic artery, the main supply for the ophthalmic artery comes from the cavernous segment of the ICA such as in this case 1 2 3 4 ( Fig. 2 , Supplementary Figs.…”
