It is due to damage inoptic nerve or severe retinal disease. It is important to be able to differentiate whether a patient is complaining of decreased vision from an ocular problem such as cataract or from a defect of the optic nerve. Communication in the body occurs primarily through two systems: the nervous system and the endocrine system. Regardless of the system used, if communication flows toward the control center from the receptor, it is termed an afferent pathway. If information flows from the control center to the effector, it is termed an efferent pathway. Afferent neurons, also known as sensory neurons, are responsible for carrying sensory information from the body's tissues and organs to the central nervous system (CNS).
