This resource offers comprehensive instruction on the diagnosis and treatment of all varieties of eye movement disorders, and reflects the importance of correlating clinical signs of disorders in the oculomotor system with their neuroanatomic and neurophysiologic architecture. With its focus on signs and symptoms, it advances lesion localization of eye movement disorders as the central clinical concern, and presents a fresh review of bedside examination techniques in the ER, ICU, and walk-in clinic; productive ways of taking a clinical history; sign interpretation; source lesion localization; and, where appropriate, therapy. This resource is arranged according to objective signs - like ptosis, neuromuscular syndromes, dizziness, vertigo, and syndromes of the medulla - rather than disease entities, and features over 50 clinical cases, each one providing the anatomical guidance needed to make critical diagnostic and management decisions in patients who often present with abnormal eye movements.
