Horner's syndrome	Horner's syndrome is a clinical syndrome caused by damage to the sympathetic nervous system resulting in ptosis (drooping upper eyelid), miosis (constricted pupil), and occasionally enophthalmos (the impression that the eye is sunk in) and anhidrosis (decreased sweating) on one side of the face. Horner's syndrome is usually acquired but may also be congenital. Although most causes are relatively benign, Horner's syndrome may reflect serious pathology in the neck or chest (such as a Pancoast tumor) and hence requires workup. (references)
