[The Oculomotor, Trochlear, and Abducens Nerves].

Abstract

Saccade and vestibular eye movements, which direct and maintain gaze towards an object, respectively, are produced by different neural mechanisms. The oculomotor, trochlear, and abducens nerves work together to move the extraocular muscles to achieve these eye movements. Recognizing eye movement disorders that occur with disorders of each nerve is useful towards the diagnosis and localization of the insulting lesion. Disorders in the central neural mechanisms of saccade and vestibular eye movements also cause abnormalities in eye movements, making it necessary to understand the eye movement abnormalities that occur with disorders of the saccade and vestibular eye movement neural mechanisms.
