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.
The vast majority of optic nerve fibres convey information regarding central vision. 1  The optic nerve begins at the optic disk, a structure that is 1.5 mm (0.06 inch) in diameter and is located at the back of the eye. The optic disk forms from the convergence of ganglion cell output fibres (called axons) as they pass out of the eye.
