Horner syndrome


Horner syndrome

 [hor´ner] sinking in of the eyeball, ptosis of the upper eyelid, slight elevation of the lower lid, constriction of the pupil, narrowing of the palpebral fissure, and anhidrosis caused by paralysis of the cervical sympathetic nerve supply.

Hor·ner syn·drome

(hōr'nĕr), [MIM*143000] ipsilateral myosis, ptosis, and facial anhydrosis; usually unilateral and due to an ipsilateral lesion of the cervical sympathetic chain or its central pathway; an ominous sign when it accompanies an ipsilateral traumatic brachial plexopathy because it usually indicates an avulsion of the C8 and T1 primary roots from the spinal cord. Synonym(s): Bernard-Horner syndrome, ptosis sympathetica
