Little or delayed dilation of the affected pupil in dim light. The levator palpebrae superioris muscle elevates the upper eyelid. 2 This article will cover the classification and causes of Horner's syndrome. The nerve pathway that may be disrupted — sometimes leading to Horner's syndrome — is comprised of three different types of nerve cells, or neurons: first, second, and third-order neurons. In the congenital form, the iris is not pigmented and remains blue-grey. The nerve pathway affected in Horner syndrome is divided into three groups of nerve cells (neurons).

Horner syndrome is a rare condition classically presenting with partial ptosis (drooping or falling of the upper eyelid), miosis (constricted pupil), and facial anhidrosis (absence of sweating) due to a disruption in the sympathetic nerve supply. Horner's syndrome, the triad of miosis, ptosis, and enophthalmos, is a common complication of regional blockade of the brachial plexus, following disruption of sympathetic nerve input from the cervical sympathetic ganglia [1 A]. The syndrome is not painful and does not interfere with vision. "Horner's syndrome is often classified as idiopathic, which means it is without known cause." Horner's syndrome results from an interruption of the sympathetic nerve supply to the eye and is characterized by the classical triad of miosis (ie, constricted pupil), partial ptosis, and loss of hemifacial sweating (ie, anhidrosis). Approximately 60% of cases studied are from known causes and the other 40% are idiopathic 1 .The main and most common characteristics of this syndrome are ptosis of the eyelids and ipsilateral miosis of the pupil. Symptomatic Inquiry: Negative for ptosis, bulbar muscle weakness or generalized weakness to suggest myasthenia gravis. When assessing for signs and symptoms of this syndrome, the nurse should note: A. Miosis, partial eyelid ptosis, and anhidrosis on the affected side of the face. The symptoms are due to a disorder of the sympathetic nerves in the brainstem or cervical (neck) region. may administer a type of eyedrop that will cause significant dilation of the healthy eye and little dilation of the affected eye if Horner syndrome is caused by a third-order neuron abnormality — a disruption .

Horner Syndrome also is known as Horner-Bernard syndrome is a condition that arises when there is a disruption in the nerve pathway connecting the brain with face and eyes. This is part of the autonomic nervous system, which helps to control normal functions such as blinking, muscle tone, etc. In rare cases, Horner's syndrome is congenital (present from birth) and may be associated with a lack of pigmentation of the iris (colored part of the eye). Horner's Syndrome Causes The condition is caused primarily by the interruption and destruction of the nerve fibers pathway that run from the hypothalamus (part of the brain stem) to the face.
