Horner syndrome involves miosis or constriction of the pupils, ptosis or the drooping of the eyelid, and anhidrosis which is an inability to sweat in the face.

Horner征包括瞳孔缩小、上睑下垂以及面部无。

This leads to Horner's syndrome on the same side of the face as the lesion, which include symptoms of miosis or constricted pupil, ptosis or droopy eyelid, and anhidrosis or failure to sweat.

这会导致在病损同侧脸部出现霍征，症状包括瞳孔缩小、眼睑下垂与脸部无。
