Apraclonidine Testing in Horner's syndrome | This patient experienced relatively abrupt ptosis and was seen and diagnosed with a Horner's syndrome within a few days of the onset. There were no other exam findings and history did not offer clues as to the etiology. Neuroimaging of the oculosympathetic tract was unrevealing. Apraclonidine testin... | Image/MovingImage |
