AB  - The  optic  nerve  is  the  structure  at  the  back  of  the  eye  that  carries  visual  information  from  the  eye  to  the  central  nervous  system  (CNS).  Approximately  120  million  rods  and  cones  sense  light  in  the  outer  retina.  This  information  is  transmitted  to  approximately  1  million  ganglion  cells  in  the  inner  retina.  These  ganglion  cells  converge  to  form  the  optic  nerve.  The  electrical  impulses  generated  in  the  optic  nerve  are  transmitted  to  the  occipital  lobe  via  the  lateral  geniculate  nucleus.  Posterior  to  the  eye,  the  optic  nerve  is  covered  by  a  dural  sheath  and  arachnoid  membrane.  This  structure  surrounds  the  nerve  until  it  enters  the  brain,  where  it  is  contiguous  with  the  subdural  space  (Figure  33–1).
