Abstract
To locate a lesion in nervous system and to know its causes, oculomotor abnormalities play a key role. Diplopia, palpebral ptosis and nistagmus are the main sign and symptoms of extrinsic oculomotor abnormalities. Neurological diplopia is binocular, meanwhile ophthalmic and, sometimes, psychogenic diplopia is monocular. Several types of eye movements are involved in the fixation and stabilization of images, both at rest and during movement. Various cortical areas and subcortical regions in the ganglia of the base, brainstem and cerebellum are responsible for transmitting the signals to the cranial nerves that innervate extraocular muscles. A wide number of lesions located in central nervous system and ocular cranial nerves, neuromuscular junction and extraocular muscles lead to oculomotor symptoms and signs.
