optic nerve
The optic nerve can be identified with the sense of sight.
The junction of the retina and optic nerve is called the optic disc or optic nerve head. This is where the optic nerve exits the eye and carries visual information from the retina to the brain. The optic disc is also known as the blind spot because it lacks photoreceptor cells and cannot detect light.
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.
The term is "optic disc" or "optic nerve head." This is the point in the eye where the optic nerve exits and carries visual information to the brain.
