WebMar 31, 2024 · Anatomy. The optic nerve is mainly made up of the axons (nerve fibers) of the retinal ganglion cells from the retina. The optic disc or nerve head is the point where the axons from the retinal ganglion cells leave the eye. The nerve head appears as a white circular structure in the back of the eye. There are no photoreceptors on this structure.
