These palsies can occur when pressure is put on the nerve or the nerve does not get enough blood. People have double vision when they look in a certain direction, the eyelid droops, and the pupil may be widened (dilated).

A third nerve palsy with pupillary sparing is often termed a medical third palsy and often has an ischaemic or diabetic aetiology. Full assessment of oculomotor nerve function involves testing of movement, reaction to light, and accommodation.

A palsy of the 3rd cranial nerve can impair eye movements, the response of pupils to light, or both. These palsies can occur when pressure is put on the nerve or the nerve does not get enough blood.
