Shrinking pupils, drooping eyelids, and invaginations

Horner's syndrome refers to a characteristic group of eye symptoms caused by autonomic nerves, mainly damage to the sympathetic ganglia of the neck. The disease can occur if any segment of the cervical sympathetic pathway is damaged. However, it is extremely rare to have central nervous system disease above the first thoracic spinal cord. The main manifestations are: reduced pupil on the affected side, small eye splits, invaginated eyes, less or no sweat on the face. This phenomenon is called Horner syndrome. Also known as Horner syndrome.
