From the Ophthalmological Clinic, University of Ghent (Director, Prof. Fran! rois), and the institute ofRadiology, University ofLiege (Director, Prof. Leroux) THE literature gives few details of the intimate vascularization of the optic pathway. Leber (1903) found in the optic nerve a vascular network, composed of round meshes; he described other vessels running obliquely along the whole length of the optic nerve, which became smaller with more closely woven meshes at the level of the lamina cribrosa. Wolff (1948) agreed with Leber that the distribution of the septa containing the vessels between thenervous tissue bundles reflected the vascular pattern. The branches, which derived from the very rich pial vascular network, penetrated dichotomously into the optic nerve, the septa gradually disappeared towards the intracanalicularand cranial sections, and in the centre the capillaries were less frequent and the meshwork looser (cf. also Behr, 1935).Fazio and Farina (1940) deduced from horizontal sections (not from in-jection) the existence of an irregular quadrangulated meshwork, orientated lengthways, built up by very small capillaries, and of equal density at the periphery and centre. Towards the optic foramen the capillaries and meshes were wider and still more irregular, and in the intracranial section a great number of very small vessels ran parallel. Eisler (1930) indicated the possibility of a network with longitudinal meshes in the sheath of the optic nerve. The subject obviously requires further investigation. Technique
