Occipital nerve. It is the second cranial nerve.
Normally, this is inherited, but if it is not, then considerable damage to the Optic Nerve, Retina, or higher brain can cause this.
Point where optic nerve enters eyeball is the optic disc.
The junction between the retina and the optic nerve is the optic disc.
Optic nerve. Well, it connects the retina to the brain. The muscles of the eye also connect to the brain, but not through the optic nerve.
The optic nerve can be identified with the sense of sight.

The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
