The eye drop tests may involve two steps:Īpplying eye drops that contain small amounts of cocaine or apraclonidine to both eyes. These tests may include:Īngiogram, which provides a view of the arteries Furthermore, tests may be needed to pinpoint the cause. Horner’s syndrome diagnosisĪn eye doctor may be able to confirm Horner’s syndrome with a special eye test. For some people with congenital Horner’s syndrome, their carotid artery has not developed properly (agenesis). These nerves can be damaged as a result of birth difficulties, surgery or accidental injury, as well as benign or cancerous tumors. The cervical sympathetic nerves control several functions in the eye and face such as pupil dilation and facial sweating. Most cases of congenital Horner’s syndrome result from damage to nerves known as the cervical sympathetics. In a few rare instances, congenital Horner’s syndrome appears to be an inherited genetic trait. Cardiothoracic surgery involves procedures on the heart, lungs and esophagus.

Neuroblastoma is a cancer that starts in nerve cells (called neuroblasts) of the sympathetic nervous system. In children, one of the most common causes of Horner’s syndrome is neuroblastoma. In other cases, the disorder may be genetically inherited. Some cases of Horner syndrome occur for no apparent reason, according to the National Organization for Rare Disorders.

Neck and ear pain on one side of the body Vertigo, coupled with nausea and vomiting Symptoms that may accompany Horner’s disease, but are not directly caused by it, include: While vision and health normally aren’t harmed by Horner’s syndrome, the nerve damage that triggers this disorder may be a sign of other health problems.
