WebOculomotor nerve palsy or oculomotor neuropathy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior … WebBecause the 3rd cranial nerve also raises the eyelids and controls the pupils, the eyelid droops. The pupil may be normal or be widened (dilated) and may not narrow (constrict) in response to light. The pupil is often affected when the cause is compression of the 3rd cranial nerve. When the pupil is not affected, the cause is often inadequate ...

The nerve also contains fibers that innervate the intrinsic eye muscles that enable pupillary constriction and accommodation (a… WebThe cranial nerves are a set of 12 paired nerves in the back of your brain.

Cranial Nerves: Function, Anatomy and Location - Cleveland Clinic
WebThe oculomotor nerve is the third cranial nerve (CNIII). It has somatic motor (general somatic efferent) and visceral motor (general visceral efferent-parasympathetic) functions. Basically, the oculomotor nerve has three major functions which include: Innervation of eye muscles for for gaze fixation and eye tracking (somatic motor) Webread more may indicate a defect in bilateral coordination of eye movements (eg, in neural pathways) or in the 3rd (oculomotor), 4th (trochlear), or 6th (abducens) cranial nerve. If diplopia persists when one eye is closed (monocular diplopia), the cause is probably a nonneurologic eye disorder.
