Abstract
In my anatomical study of 106 human central retinal artery (CRA) [1, 2], I found two specimens with two CRAs, each arising independently from the ophthalmic artery (Fig. 14.1). In one of these specimens, the two CRAs pierced the sheath of the optic nerve 12 mm and 5 mm behind the eyeball on its inferolateral aspect and then ran independently in the optic nerve up to the optic disc. At the optic disc, the two joined to form a loop, from the summit of which arose terminal branches which followed the usual course. In the second specimen, the two CRAs arose independently from the ophthalmic artery, and they united to form one trunk at the point of entry into the sheath of the optic nerve. As far as I know, there has not been any other report with anatomical proof of the presence of two CRAs in the same eye.
