Horner’s syndrome is a rare condition caused by a brainstem abnormality or damage to the sympathetic nerves that go to the eye and face on the same side. It can be caused by a stroke, tumor or injury to the brainstem. The damage to the sympathetic nerves can occur in a number of different locations. Some examples are a tumor in the lung or neck, brachial plexus injury, or a carotid artery dissection. Rarely, a person can be born with Horner’s syndrome.

Horner’s syndrome is a combination of a drooping of the upper eyelid, a small constricted pupil, and dry skin all on the same side of the face. The dry skin is due to lack of sweating.

Horner’s syndrome itself is not dangerous and does not necessarily require treatment. However, it is usually a sign of something more serious. Treatment of the underlying disorder may improve the symptoms.
