Optic Disc & Optic Nerve. The optic disc is a round area in the back of the eye where retinal nerve fibers collect to form the optic nerve. The optic disc is sometimes called the optic nerve head because it is the head of the optic nerve as it enters the eye from the brain. It is located slightly to the nasal side of the globe. The optic disc is known as the blind spot because it contains no photoreceptors.
the optic nerve (Cn 2) runs along the optic tract to the optic chiasm, where the left optic nerve goes the left side of both eyes, and the right optic nerve goes to the right side of both eyes (NOTE: once the branches of the L & R nerves leave the optic chiasm and run together, they are referred to as ONE nerve); the left Cn 2 is responsible for the right visual field in both eyes, and the right Cn 2 is responsible for the left visual field of both eyes
