Y1 - 2014 N1 - T2 - Adams and Victor's Principles of Neurology, 10e AB - The importance of the visual system is attested by the magnitude of its representation in the central nervous system (CNS). A large part of the cerebrum is committed to vision, including the visual control of movement and the perception of printed words, and the form and color of objects. The optic nerve, which is a CNS structure, contains more than a million fibers (compared to 50,000 in the auditory nerve). The visual system also has special significance in that study of this system has greatly advanced our knowledge of both the organization of all sensory neuronal systems and the relation of perception to cognition. Indeed, we know more about vision than about any other sensory function. Furthermore, the eyes, because of their diverse composition of epithelial, vascular, neural, and pigmentary tissues, are virtually a medical microcosm, susceptible to many diseases, and its tissues are available for inspection through a transparent medium.
