[Blood circulation of the optic nerve with respect to the development of glaucomatous papilla excavation].
Recent research findings in microvascular anatomy enable the authors to make as new suggestion regarding the arrangement of the intraorbital vasculature of the optic nerve. In anatomical specimens three separate zones can be identified, sharply delimited and each with its own source of blood supply. After briefly describing the vasculature of the distal segment (neck) of the optic nerve the authors report several new theories concerning the pathogenesis of glaucomatous cupping of the optic disk.
