Persistent Dorsal Ophthalmic Artery Arising from the Internal Carotid Artery: Report of Three Cases

open access: yes대한영상의학회지, 2016
Normally, the ophthalmic artery (OA) arises from the supraclinoid segment of the internal carotid artery (ICA) and enters the orbit via the optic canal. A persistent dorsal OA is a rare variation that originates from the cavernous segment of the ICA and ...

Ophthalmic artery Doppler in the prediction of preeclampsia [PDF]

open access: yesAmerican Journal of Obstetrics and Gynecology, 2022
The ophthalmic artery is an easily accessible vessel for Doppler assessment that provides information on the less accessible intracranial circulation. In women with preeclampsia, compared with normotensive pregnant women, there is a decrease in impedance to flow and an increase in velocities in the flow velocity waveforms from the ophthalmic arteries ...
