Answer: With an oculomotor nerve palsy, the eye is turned down and out. This is because almost every eye muscle is affected. The only muscles still in action are the abducens (turn the eye outwards) and the superior oblique (move the eye down).
Causes for third nerve palsy include an ischemic event from diabetes or hypertension. Also, an aneurysm pushing on the nerve. at the junction of the internal carotid and posterior communicating arteries.
