Oculomotor Nerve Diseases

Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)

Abstract

Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression.

Indexing Annotation

do not confuse entry term OCULOMOTOR NERVE PALSY with oculomotor palsies caused by weakened 4th or 6th cranial nerves which are indexed: 4th= TROCHLEAR NERVE DISEASES and 6th= ABDUCENS NERVE DISEASES, if not specified use CRANIAL NERVE DISEASES; neoplasms: coordinate with CRANIAL NERVE NEOPLASMS + histologic type of neoplasm; do not confuse with OCULOMOTOR PARALYSIS see OPHTHALMOPLEGIA
