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.
Developmentally, both the optic nerve & retina are outgrowths of brain. Optic nerve fibers from the retina converge on the optic disc, pierce near the posterior pole of the eyeball where four recti and ciliary vessels & nerves surround it. In the optic canal, it is related superomedially to the ophthalmic artery & nasociliary nerve.
