A three-dimensional study showed the existence of three vascular networks in the optic nerve: a peripheral, a periaxial and an axial one. The axial network, which was seen in 30% of the specimens, was formed by ramifying collateral branches from the pia mater of the optic nerve, but in the anterior part of the optic nerve there was an axial system which entirely depended on branches of the central retinal artery. This artery had important anastomoses with branches originating from the pia mater of the optic nerve and other collateral branches originating from the ophthalmic artery and its branches (the ciliary system).
一项三维研究显示，视神经中存在三种血管网络：外周网络、轴周网络和轴内网络。轴内网络见于30%的标本中，由视神经软膜的分支侧支形成，但在视神经前部存在一个完全依赖视网膜中央动脉分支的轴内系统。该动脉与源自视神经软膜的分支以及源自眼动脉及其分支（睫状系统）的其他侧支有重要的吻合。
