Middle Meningeal Origin of the Ophthalmic Artery

Unilateral absence of foramen spinosum with bilateral ophthalmic origin of the middle meningeal artery: case report and review of the literature

“…The MMA occasionally gives off the ophthalmic artery [21]; rarely, the ophthalmic artery may give off the anterior division of the MMA [18] and, more rarely, the ophthalmic artery may give off the main stem of the MMA, as in the case presented.…”

Orbital vascular anatomy

“…1,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] This mode of origin was seen in six specimens (four persons) in my study 2 (Figures 6b-e). It is by enlargement of anastomoses between the recurrent branch of the lacrimal artery and the orbital branch of the middle meningeal artery through the superior orbital fissure or a foramen in the greater wing of the sphenoid.…”

Anomalous Origin of the Ophthalmic Artery From the Anterior Cerebral Artery -Case Report-

“…16) Eighteen cases of anomalous origin of the OphA were reported between 1969 and 2010. [2][3][4]8,[10][11][12][13][14][15][16][17][18]20,21) Table 1 summarizes the clinical characteristics of anomalous origin of the OphA. Mean age of the patients was 44.1 years.…”

“…The OphA may also arise extradurally from the clinoidal segment or the intracavernous portion of the ICA and pass through the superior orbital fissure instead of the optic foramen. 1,6) Other origins of the OphA include the middle meningeal artery (MMA), 4,[10][11][12]14,20,21) basilar artery (BA), 17,18) posterior communicating artery (PCoA), 13,15) and ICA bifurcation. 2) The OphA originating from the anterior cerebral artery (ACA) is extremely rare.…”
