“…In this case, the OA enters the orbit through the superior orbital fissure or a duplication of the optic canal [25, 56]. The origin of the OA from the intracavernous ICA is usually referred to as the persistence of the PDOA [8, 63]. However, it has recently been observed that this interpretation was based on a misreading of Padget’s work [16].…”

“…The aberrant stemming from the anterior cerebral artery is another rare variant of the OA origin [3, 4, 18, 20, 21, 26, 28, 37, 63]. This variation has been frequently explained with the persistence of the PVOA [3, 4, 26, 28, 37, 63], though it more probably involves a persistent recurrent POlfA (Fig.…”

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.

“…Extremely rarely, the OphA arises from the A1 segment of the ACA (Fig. 6.7) [9]. According to Padget [10], the ventral OphA arises from the cranial branch of the primitive ICA and migrates caudally to the normal position of the origin of the OphA.…”

This chapter includes (1) Ophthalmic artery arising from the cavernous internal carotid artery (Persistent dorsal ophthalmic artery), (2) Double ophthalmic arteries arising from the internal carotid artery, (3) Ophthalmic artery arising from the middle meningeal artery, (4) Double ophthalmic arteries arising from the internal carotid artery and middle meningeal artery, and (5) Ophthalmic artery arising from the anterior cerebral artery. There are 7 figures and 1 illustration.Ophthalmic artery arising from the middle meningeal artery is not uncommon and is particularly dangerous during catheter intervention in the external carotid artery territory.

“…The anomalous origin can be from external carotid artery (ECA) branches, middle meningeal artery (MMA), ICA branches, anterior cerebral artery (ACA), basilar artery (BA) or posterior communicating artery (PcomA). 1–5 We are reporting the first case of bilateral ICA aneurysms with both side anomalous origin of OAs from MMA.…”

Bilateral anomalous origin of ophthalmic artery from middle meningeal artery and coincidence of bilateral carotid artery aneurysm: Case report and literature review

et al. 2020

Ophthalmic artery (OA) is known for anomalous origin and aberrant course probably attributable to its complex embryology. Anomalous origin of OA can be associated with intracranial aneurysm. Anomalous origins have been reported from middle meningeal artery (MMA), cavernous carotid, posterior communicating, anterior cerebral and basilar artery. Even though bilateral anomalous origin of OA from MMA is a rare finding, to the author’s best knowledge, association of above condition with bilateral internal carotid artery aneurysms has not been described in the literature. We present a case of such anomalous bilateral OA originating from MMA and associated with bilateral internal carotid artery aneurysms. We have also reviewed the pertinent literature regarding anomalous OA origin.
