In rare cases, Horner's syndrome may be the result of repeated, minor head trauma, such as being hit with a soccer ball. Although most causes are relatively benign, Horner's syndrome may reflect serious disease in the neck or chest (such as a Pancoast tumor (tumor in the apex of the lung) or thyrocervical venous dilatation).

When the triad of an ipsilateral Horner's syndrome, shoulder/arm pain and weakness of the intrinsic hand muscles occurs, the presentation is called the Pancoast syndrome. This syndrome is due to involvement of brachial plexus roots and that of sympathetic fibers as they exit the cord at T1 and ascend to the superior cervical ganglion. [11] [10]
Lesions of the hypothalamospinal tract above spinal cord level T1 cause ipsilateral Horner's syndrome, which is characterized by a triad of ptosis, miosis, and anhidrosis due to sympathetic denervation of the face. [6]
Anisocoria has various causes: [3] Physiological anisocoria: About 20% of the population has a slight difference in pupil size, which is known as physiological anisocoria. In this condition, the difference between pupils is usually less than 1 mm. [4] Horner's syndrome
Horner's syndrome is a disorder resulting from damage to the sympathetic autonomic nervous pathway in the head. Damage to the SCG, part of this system, often results in Horner's syndrome. Damage to the SCG, part of this system, often results in Horner's syndrome.
The damage to the cerebellum or the inferior cerebellar peduncle can cause ataxia. Damage to the hypothalamospinal fibers disrupts sympathetic nervous system relay and produces symptoms that are similar to the symptoms caused by Horner's syndrome – such as miosis, anhidrosis and partial ptosis.

Left stellectomy is a treatment strategy in prolonged QT syndrome because activity of the stellate ganglia drives prolonged QT. However, this therapy is only offered to patients who are already on a beta blocker and experience frequent shocks from an implantable cardioverter-defibrillator (ICD), because stellectomy causes Horner's syndrome.
