Gross anatomy

The central artery of the retina courses anteriorly and inferior to the optic nerve, It then pierces the dura and the arachnoid of the optic nerve. It then runs in the centre of the optic nerve with the central vein of the retina. It pierces the lamina cribrosa to enter the globe, where it divides into four branches to supply each quadrant of the globe.
