Learning Center > Health Library > Optic Nerve. The optic nerve is located in the back of the eye. This structure is responsible for transferring the images we see from the retina to the brain. The front surface of the optic nerve, which is visible on the retina, is called the optic disc.
In humans, the optic nerve extends from the optic disc to the optic chiasm and continues as the optic tract to the lateral geniculate nucleus, pretectal nuclei, and superior colliculus.he 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.
