A condition caused by paralysis of the sympathetic nerve in one side of the neck, making the eyelids hang down and the pupils contract [Described 1869. After Johann Friedrich Horner (1831-86), Professor of Ophthalmology in Ziirich, Switzerland.]
Group of symptoms—drooping upper eyelid, constricted pupil, absence of facial sweating— occurring as a result of damage to nerves in the cervical (neck) region of the spine.
A set of physical changes that includes drooping eyelid (ptosis), sinking eyeball, narrowed pupil, and facial dryness. Horner syndrome occurs as a result of damage to the sympathetic division of the autonomic (involuntary) nervous system. It has many possible causes, including injury to the spinal cord, vascular disease, and tumors in the neck or chest that impinge on nerves. Diagnosis entails detailed and rigorous evaluation and may require tests such as imaging studies of the head, neck, and chest. Treatment depends on the underlying cause.
This is the description given to a combination of changes resulting from paralysis of the sympathetic nerve in the neck. They are: a small pupil; a drooping upper lid; and an apparently (though not actually) sunken eye.
A syndrome characterized by contraction of the pupil, partial ptosis of the eyelid, enophthalmos, and sometimes loss of sweating over one side of the face. The syndrome is caused by paralysis of the cervical sympathetic nerve trunk, often as a result of an anesthetic mishap or a tumor in the superior sulcus of the lung.
A cluster of physical signs, including the narrowing of the eye pupil, drooping of the eyelid, and lack of sweating, occurs on one side of the face when there is damage to a section of the sympathetic nervous system. These signs collectively indicate a condition affecting the sympathetic innervation of the face.
Ptosis (sagging of the upper eyelid), enophthalmos (sunken eye), constricted pupil, absence of sweating, and reduced facial expression on the affected side of the face. This condition results from paralysis of the cervical sympathetic nerves in the neck, typically due to factors like trauma, pressure, tumors, brain or spinal cord disorders, or syphilis.
