Popis: | Retinal axons are bundled at the inner disc and supplied by a specific arteriole, the arteria centralis retinae, observed in most mammals but absent in birds. These axons form the optic nerve, which pierces the choroid and sclera at the optic nerve head, where it is supplied by the ciliary system, initially irrigating also the functional complex of retinal sensors and receptors, the retinal pigment epithelium and Bruch's membrane (membrane of Ruysch), which is never supplied by the arteria centralis retinae. Behind the lamina cribrosa the nerve expands by myelination into the afferent optic nerve, with a consistent topographic distribution of the axons, surrounded by a meningeal pio-arachnoido-dural sheath, from where arterioles supply the entire retrolaminar optic nerve up to the chiasm. |
