The patient with thyrotoxicosis has protruding eyes or exophthalmos, not swollen eyelids or periorbital edema. Albinism is a genetic disorder, characterized by the absence of melanin pigment, which gives color to skin, hair, and eyes. Therefore the kidneys may not be able to filter the blood properly, resulting in edema. This results in decreased blood supply to the kidneys. The patient with congestive heart failure has low cardiac output. Therefore the patient with renal failure may have periorbital edema. During renal failure, the filtration capacity of the kidney is decreased and results in retention of fluids. Low thyroid hormone levels may result in an accumulation of excessive fluid in the tissue around the eyes, leading to periorbital edema. A patient with myxedema or hypothyroidism has low levels of thyroid hormones. This is known as idiopathic Horner syndrome.Periorbital edema is a condition in which excess fluid accumulates around the eyes, resulting in a swollen or puffy appearance of the eyelids. In some cases, the cause of Horner syndrome cannot be identified.

Tumor of the hormonal and nervous systems (neuroblastoma).

Injury to the neck or shoulders during delivery.

The most common causes of Horner syndrome in children include:

Cluster headaches, a disorder that results in cyclical patterns of severe headaches.

Tumor or infection near the base of the skull.

It can be difficult to distinguish pupils different when small aperture pupils look like the. Patients with nonreactive pupils had the highest peaks of ICP (mean 33.8 mmHg, P 0.0046). Results Patients with abnormal pupillary light reactivity had an average peak ICP of 30.5 mmHg versus 19.6 mmHg for the normal pupil reactivity population ( P 0.0014).

Damage to the jugular vein along the side of the neck A pupils unequal is usually caused by unequal apertures (diameter). Pupillary examination was performed using a portable hand-held pupillometer.Damage to the carotid artery along the side of the neck.Nerve damage in this region may be associated with the following:

#Unequal pupil size with dysfunction skin#

This neuron path extends along the side of the neck and leads to facial skin and muscles of the iris and eyelids.

Damage to the main blood vessel leading from the heart (aorta).

Tumor of the myelin sheath (schwannoma).

Causes related to nerve damage in this region may include: This neuron path extends from the spinal column, across the upper part of the chest and into the side of the neck.

Cyst in the spinal column (syringomyelia).

Diseases that cause the loss of the protective sheath on neurons (myelin).

Problems in this region that can disrupt nerve function related to Horner syndrome include: This neuron pathway leads from the hypothalamus at the base of the brain, passes through the brainstem and extends into the upper portion of the spinal cord. The nerve pathway affected by Horner syndrome is divided into three groups of nerve cells (neurons). The sympathetic nervous system regulates heart rate, pupil size, perspiration, blood pressure and other functions that enable you to respond quickly to changes in your environment. Horner syndrome is caused by damage to a certain pathway in the sympathetic nervous system. Request an Appointment at Mayo Clinic Causes

Muscle weakness or lack of muscle control.

Get emergency care if signs or symptoms associated with Horner syndrome appear suddenly, appear after a traumatic injury, or are accompanied by other signs or symptoms, such as: It is important to get a prompt and accurate diagnosis.

Change in color on the affected side of the face that would typically appear from heat, physical exertion or emotional reactionsДЄ number of factors, some more serious than others, can cause Horner syndrome.

Lighter iris color in the affected eye of a child under the age of 1.

A lesion in the sympathetic nervous system may lead to Horner syndrome in the patient, in which a unilateral pupil does not react to light and accommodation. The patient with Adie's pupil may have a problem with near vision because of sluggish accommodation of a unilateral pupil. ChildrenДЄdditional signs and symptoms in children with Horner syndrome may include: Anisocoria refers to the presence of an unequal pupil size. Signs and symptoms, particularly ptosis and anhidrosis, may be subtle and difficult to detect.

Little or no sweating (anhidrosis) on the affected side of the face.

Slight elevation of the lower lid, sometimes called upside-down ptosis.

Little or delayed opening (dilation) of the affected pupil in dim light.

A notable difference in pupil size between the two eyes (anisocoria).

Horner syndrome usually affects only one side of the face.
