clinical features
Last reviewed 01/2018
Horner's syndrome comprises:
- ipsilateral miosis and partial ptosis
- ipsilateral anhidria on the face
- there is no enopthalmos, although the narrow palpebral aperture may suggest it
Also:
- despite the ptosis - normal range of lid movement in and up and down movement - supplied by the third nerve
- despite the miosis, the pupillary response to light and the near reflex are brisk and sustained but dilation of the Horner's pupil in response to darkness is diminished or absent
- the degree of miosis is not related to the level of the lesion i.e. whether central, pre- or post- ganglionic
