Horner's syndrome resulting from a prolonged abnormal posture during a coma

Horner's syndrome results from the impairment of the sympathetic nerve supply to the eye and orbit. Other nerve palsies from prolonged unchanged posture are well described, but Horner's syndrome following prolonged lateral flexion has only twice been seen previously and these cases were in association with anaesthesia.

A case is described of Horner's syndrome resulting from a prolonged period of unchanged posture from an alcohol-induced coma. A review of the anatomy of Horner's syndrome is presented.

To my knowledge, this is the first reported case of Horner's syndrome resulting from a coma.
