Title: Anatomic variation of ophthalmic artery and its clinical significance
Abstract: Objective:To investigate anatomic variation of ophthalmic artery and its clinical significance. Methods: Through anatomic dissection under operation microscope, the origin and location of ophthalmic artery,its relation with the dural ring, communicating branches between it and middle meningeal arteries were examined and analyzed in 15 cases (30 sides) formalin-fixed specimens. Results: 93.3% of ophthalmic arteries originated from internal carotid artery, while 6.7% from middle meningeal artery. Ophthalmic artery originated from the internal carotid artery within the intradural space in 53.3% of cases, just above the upper dural ring in 30%, at the clinoid segment in 6.7%, and within the cavernous sinus in 3.3%. 25% of cases presented communicating branches between ophthalmic arteries and middle meningeal arteries. Conclusions:The origin of ophthalmic artery is variable. It usually gives off abnormal communicating branches, which should be evaluated before embolismic operation of maxillary artery.
