This new edition of Neurology of Eye Movements is a major revision providing clinicians with a synthesis of current and new scientific information that can be applied to the diagnosis and treatment of disorders of ocular motility. Basic scientists will also benefit from descriptions of how data from anatomic, electrophysiologic, pharmacologic, and imaging studies can be directly applied to the study of disease. By critically reviewing such basic studies, Drs. Leigh and Zee build a conceptual framework that can be applied to the interpretation of abnormal ocular motor behavior at the bedside. These syntheses are summarized in boxes, figures, schematics, and tables. Insights and techniques from current research, case examples, bedside and laboratory studies, and thousands of references are all available here from two leading clinician-scientists who have been studying eye movements for over a quarter century. The previous edition of Neurology of Eye Movements, Third Volume, established as acknowledged as a classic in the field, is now enhanced in this new edition by an accompanying DVD featuring the full text with links to 20 Video Displays that provide teaching slides ready for classroom presentation. Also on the DVD are 200 video clips, images, and the lectures notes Control Systems Applied to the Oculomotor System by David A. Robinson.
