Teaching NeuroImages: Positive apraclonidine test in Horner syndrome.
A 36-year-old woman reported right eyelid drooping immediately after anterior cervical discectomy and fusion. Examination 2 weeks later revealed right miosis and right ptosis (figure, A).

We describe a patient with HS secondary to carotid dissection who had a positive response to apraclonidine 3 hours after the onset o...
