Third Cranial Nerve Palsy

Third cranial nerve palsy is a disorder of the oculomotor nerve, which is responsible for much of the movement of the eye and the eyelid. When it is affected, the eye loses part of its normal mobility.

Common symptoms: double vision, drooping of the eyelid, and, depending on the cause, changes in pupil size or difficulty directing the eye in certain directions.

When to see a doctor? A sudden onset of these signs warrants a prompt evaluation to clarify its origin.

Which specialists treat it? The general practitioner may be the first point of contact, pediatrics evaluates children, and endocrinology becomes involved when metabolic causes are suspected. In the face of double vision or a recently drooping eyelid, it is advisable for a professional to examine the case.
