“…A similar in-depth investigation has never been performed by angiography on adult orbits. Indeed, most of the current knowledge on orbital hemodynamic in adults come from Doppler ultrasonography (US) studies [ 38 ]. According to such studies, in the absence of vascular pathology, an ICA dominance in the orbit seems the rule.…”

“…According to such studies, in the absence of vascular pathology, an ICA dominance in the orbit seems the rule. However, though Doppler US provides valuable information [ 38 ], it does not supply a comprehensive view of the orbital circulation and some important details may escape. In particular, the ultimate source of the blood flowing within the orbit is difficult to estimate.…”

An update on the variations of the orbital blood supply and hemodynamic

PurposeSeveral variations of the arterial blood supply of the orbit have been reported over the years. This review is aimed to provide an update focusing on three important issues: (a) variations of the ophthalmic artery origin; (b) contribution of the external carotid artery to the orbital blood supply; (c) orbital hemodynamic.MethodsA PubMed and Google search was carried out with the following keywords: ophthalmic artery origin, ophthalmic artery anastomoses and ophthalmic artery anatomy.ResultsThe site of origin of the ophthalmic artery displays a limited number of variations. However they are important as they are also associated with course variations. Anastomoses between the ophthalmic artery and the external carotid artery are numerous and many of them can acquire clinical relevance. Records on their anatomic frequency are limited. Orbital hemodynamic variations are a poorly studied subject. Recent investigations in children have unveiled unexpected variability and instability in the way the blood flows through the orbit.ConclusionsThe orbit shows several possible arterial variations. Some of them have a profound influence on its hemodynamic at least in children. More studies are required to ascertain if the hemodynamic variability observed in children can be pinpointed also in adults.
