Optic disc

Schematic diagram of the human eye, with the optical disc, or blind spot, at the bottom.

Optic disc showing microvasculature [epiCam].

The optic disc or optic nerve head is the point of exit for ganglion cell axons leaving the eye. Because there are no rods or cones overlying the optic disc, it corresponds to a small physiological blind spot in each eye.

The ganglion cell axons form the optic nerve after they leave the eye. The optic disc represents the beginning of the optic nerve and is the point where the axons of retinal ganglion cells come together. The optic disc is also the entry point for the major blood vessels that supply the retina. The optic disc in a normal human eye carries from 1-1.2 million neurons from the eye towards the brain.
