<P> The optic nerve is ensheathed in all three meningeal layers ( dura , arachnoid , and pia mater ) rather than the epineurium , perineurium , and endoneurium found in peripheral nerves . Fiber tracts of the mammalian central nervous system ( as opposed to the peripheral nervous system ) are incapable of regeneration , and , hence , optic nerve damage produces irreversible blindness . The fibres from the retina run along the optic nerve to nine primary visual nuclei in the brain , from which a major relay inputs into the primary visual cortex . </P>
