Abstract OBJECTIVE: To define the microsurgical anatomy of the central retinal artery (CRA) and to provide a guide to avoiding damage to it during surgery. METHODS: The anatomic characteristics of the CRA and small arteries distributed to the optic sheath were examined in 109 orbits. The origin, course, and site of entry of the artery into the optic sheath and the distance between the orbital apex and the site of entry into the sheath were examined. RESULTS: The CRAs originated directly from the intraorbital ophthalmic artery or in a common trunk with a posterior ciliary or a muscular branch. The CRAs most commonly originated on the inferomedial side of the ophthalmic artery an average of 8.4 mm distal to the orbital end of the optic canal. They penetrated the optic sheath near the junction of the middle and anterior thirds of the length of the intraorbital optic nerve an average of 18.6 mm distal to the optic canal. More than 70% of CRAs penetrated near the midline of the lower surface of the optic sheath, 21% entered the inferomedial surface, and 7% the inferolateral or lateral surface of the optic sheath. Only one CRA gave off a branch before penetrating the nerve. CONCLUSION: The CRA is at risk of being damaged or occluded during procedures involving a large part of the orbit. Procedures directed along the lower half of the proximal two-thirds of the optic sheath have the greatest risk of interrupting the artery.

Abstract OBJECTIVE To examine the microsurgical anatomy and clinical significance of an anomalous origin of the ophthalmic artery from the middle meningeal artery. METHODS In the course of an anatomic study of the cavernous sinus, an anomalous ophthalmic artery arising from the middle meningeal artery was found. To further define the anatomy of the region, five additional skulls, in which the arteries and veins were injected with colored latex, were dissected using 3× to 40× magnification. RESULTS The anomalous ophthalmic artery arose from the frontal branch of the middle meningeal artery, passed through the superior orbital fissure, and supplied the entire contents of the orbit, as well as giving rise to the central retinal artery. This study provides the first display of this anomaly in an anatomic dissection. CONCLUSION The ophthalmic artery may infrequently arise from the middle meningeal artery. This anomaly places the ophthalmic artery at risk during procedures in which the dura is elevated from the greater and lesser wings of the sphenoid or when the sphenoid ridge is removed and during embolization procedures involving the branches of the external carotid artery.

Object The authors studied the microsurgical anatomy of the ophthalmic artery (OphA), paying particular attention to its possibly dangerous anastomoses with the middle meningeal artery (MMA). Methods The microsurgical anatomy of the OphA and its anastomoses with the MMA were studied in 14 vessels from seven adult cadaveric heads. The origination order of the OphA branches varies in relation to whether the artery, along its intraorbital course, crosses above or below the optic nerve (ON). The central retinal artery is the first branch to course from the OphA when it crosses over the ON, and it is the second branch to course from the OphA when the artery crosses under the ON. Anastomoses between branches of the MMA and the OphA were present in the majority of the specimens examined. Conclusions Detailed knowledge of the microanatomy of the OphA and recognition of anastomoses between the external carotid artery and the OphA are critically important in avoiding disastrous complications during endovascular procedures.
