What is Horner's syndrome?
Horner's syndrome is a rare neurological syndrome that affects the eye and one side of the face around the eye.
It is a sign of nerve damage and occurs against the background of a number of pathologies, in particular, carotid artery dissection, apical lung tumor.
The symptoms directly associated with Horner's syndrome do not significantly affect the general state of health or visual function, although it is an indication of a serious pathology and, in fact, this symptom calls for a doctor's consultation.
Horner's syndrome can occur in a person of any age, although in 5% of clinical cases it is a congenital form.
Characteristic symptoms are:
Horner's syndrome is usually caused by damage or blockage of the nerve that connects the eye to the brain. The nerve itself can be damaged by an ear infection, carotid artery dissection, or a tumor in the chest.
The congenital form of Horner's syndrome is caused by a birth injury.
Medicine also remembers very rare clinical cases when the syndrome was inherited by a baby, although the specific gene has not yet been discovered.
