Horner;s syndrome is characterized by a Ptosis i.e. drooping of the upper eyelid; b miosis i.e. constriction of the pupil; c anhydrosis i.e. loss of sweating on that side of the face; d enophthalmos i.e. retraction of the eyeball; e loss of the ciliospinal reflex i.e. pinching the skin on the nape of the neck does not produce dilatation of the pupil which normally takes place. Horner;s syndrome can also be caused by a lesion within the central nervous system anywhere at or above the first thoracic segment of the spinal cord involving sympathetic fibres. Horner;s syndrome is due to involvement of sympathetic pathways in the medulla.
