Considerations on The Origin of The Ophthalmic Artery from The Internal Carotid Artery

Abstract The study of CT angiographies performed on a CT scanner GE LightSpeed VCT16 Slice CT revealed some morphological features of the ophthalmic artery related to origin, morphometry and the internal carotid arteries in the vicinity of this artery. The diameter of the left internal carotid artery under the origin of the ophthalmic artery was between 4.0-5.8 mm and that of the right ophthalmic artery at the same level was between 4.1-5.3 mm. Under the origin of the ophthalmic artery, the internal carotid arteries were larger in diameter on the leftside in 80% of cases, with differences of 0.1-0.3 mm, and on the right side these differences were between 0.1-0.2 mm, 20% of cases. The diameter of the left internal carotid artery above the origin of the ophthalmic artery was 3.7-5.0 mm, and the origin of the right carotid artery at the same level was 3.8-5.0 mm.
