Clinical signs and symptoms requiring computed tomography and magnetic resonance imaging evaluation

A summary of some of the clinically important symptoms and signs relating to disease of the afferent visual pathways, motility, and the orbit are presented. Common disorders are discussed in the context of choosing a neuroimaging study. Specific findings (e.g., pupillary abnormalities, types of nystagmus, visual field patterns) that may affect the type of study and the anatomic area that is imaged are emphasized.
