“…The blood supply to the human lamina cribrosa has previously been studied in detail in several large series of human optic nerves (1)(2)(3)(4)(5)(6)(7). These investigations utilizing serial histopathological sectioning or various injection techniques demonstrated that the two major arterial sources of blood sypply to the lamina cribrosa arise from the short posterior ciliary arteries within the sclera and from the distal optic nerve sheath pial vasculature.…”

Vascular casts of the human lamina cribrosa region were studied in three autopsy specimens utilizing scanning electron microscopy (S.E.M.) in own modified technique. The lamina cribrosa is supplied from two major sources, the short posterior ciliary artery within the sclera and the distal optic nerve sheath pial vasculature. Recurrent choroidal arteries supplied a small number of centripetal branches to the lamina cribrosa. The central retinal artery did not give off centrifugal branches as it coursed through the lamina. The findings in these three human cases in three-dimensional visualization support other recent studies using serial histologic sectioning techniques. The photomicrographs are presented as a first successful images in S.E.M. for additional appreciation of the topographic morphology of radial arterioles.

“…A summary of these investiga tions can be found in the papers by François and Neetens [5,6], Neetens [14] and Hayreh [10][11][12]. They brought new information about the physiology and the pathology of the optic nerve vasculature [1,2,[7][8][9]12,14,15], In this paper, we will give the results of our study on the microcirculation of the anterior part of the optic nerve, especially concerning the physiological importance of the anastomoses of the central retinal ar tery. …”

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).
