Horner's Syndrome is a rare neurological condition that results from damage to the sympathetic nerves supplying the eye and surrounding structures. It is characterized by a triad of symptoms: drooping of the eyelid (ptosis), constricted pupil (miosis), and absence of sweating on the affected side of the face (anhidrosis). The syndrome can occur due to various causes, including trauma, tumors, or vascular issues affecting the neck or head. Diagnosis typically involves a thorough medical history and physical examination, often supplemented by imaging studies to identify the underlying cause of the nerve damage.
