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 II) and Visual Pathway. The optic nerve (CN II) is the second cranial nerve. In this article, we shall look at the anatomical course of the nerve, its sensory functions, and some clinical correlations. Overview. The optic nerve transmits the special sensory information for sight. It is one of two nerves that do not join with the brainstem (the other being the olfactory nerve, CN I). Embryologically, the optic nerve is developed from the optic vesicle, an outpocketing of the forebrain.
