Horner’s syndrome is most commonly caused by middle or inner ear infections (otitis media/interna) that damage sympathetic nerve pathways. Other infections, such as those causing abscesses behind the eye or severe sinus infections (rhinosinusitis), can also trigger it. In rare cases, systemic infections like disseminated herpes simplex virus (HSV) or toxoplasmosis have been associated with its development.

What infections can cause Horner's syndrome?

Most often, Horner syndrome happens as a result of blockage or damage to the sympathetic nerves that lead to your eyes. The underlying causes of nerve damage can vary widely, from a middle ear infection to a carotid artery dissection or apical chest tumor.

What is the most common cause of Horner's syndrome?

The etiology remains unknown in 35%–40% of cases. In children, trauma (birth trauma or neck trauma) is the most common cause of Horner syndrome. Other causes include surgical trauma, neuroblastoma, brainstem lesions (such as vascular malformations, glioma, and demyelination), and carotid artery thrombosis.

What other conditions mimic Horner's?

It is essential to consider other conditions that may mimic Horner's Syndrome, such as:

• Third cranial nerve palsy.
• Cluster headaches.
• Migraine with aura.
• Thyroid eye disease.

Can an ear infection cause Horner's syndrome?

Three patients developed a postganglionic Horner syndrome during the course of an ipsilateral uncomplicated middle ear infection. The mechanism may be an effect on the middle ear caroticotympanic sympathetic plexus, for which there is considerable anatomic and physiologic evidence.

Horner's syndrome - causes, symptoms, diagnosis, treatment, pathology

Can a sinus infection cause Horner's syndrome?

A few cases of HS secondary to a sinus infection have been reported in the literature. To the authors' knowledge, there are only two case reports of individuals who developed sinusitis and Horner's syndrome. The present case is the first to present isolated HS features.

Can an inner ear infection affect your eyes?

This can sometimes extend its effects to nearby areas, including the eyes, due to their close proximity. Patients may experience symptoms such as pressure behind the eyes, eye pain, or even changes in vision, though these are less common.

How urgent is Horner's syndrome?

Furthermore, Horner syndrome can be an early manifestation of neuroblastoma in the pediatric population. Carotid artery dissection can present with a unilateral headache and facial or neck pain. If suspected, urgent appropriate workup and treatment are warranted.

What cancers cause Horner's syndrome?

Common tumor-associated causes of acquired Horner's syndrome include Pancoast tumor, metastasis to cervical lymph nodes, and malignant pleural mesothelioma [8]. It may be caused by extension of the tumor into the paravertebral sympathetic nerves and/or pressure on the sympathetic plexus.

What type of doctor treats Horner's syndrome?

In most nonemergency situations, you typically start by seeing a family doctor or an (ophthalmologist). You may be referred to a doctor who specializes in nervous system disorders (neurologist) or a specialist in both neurological disorders and disorders affecting the eye and visual pathways (neuro-ophthalmologist).

Can Horner's syndrome be caused by stress?

Horner syndrome is a rare neurological condition characterized by a drooping upper eyelid, a constricted pupil, and decreased sweating on one side of the face. It is caused by damage to part of the sympathetic nervous system (which responds to dangerous or stressful situations).

What are the three classic signs of Horner's syndrome?

The three classic signs of Horner's syndrome, affecting one side of the face, are ptosis (drooping upper eyelid), miosis (constricted pupil, making pupils appear unequal), and anhidrosis (decreased sweating). These occur because of damage to the sympathetic nerve pathway from the brain to the eye and face.
 

What is the most common cause of Horner's syndrome in adults?

Causes of Horner Syndrome in Adults

• Carotid artery dissection, where the main artery in the neck tears.
• Stroke or blood vessel damage in the brain or neck.
• Tumors in the lung, chest, or neck that press on nerves.
• Injury to the neck or head from accidents or trauma.
• Complications during neck or chest surgery.

Can viruses cause ptosis?

However, there have been case reports of unusual symptoms associated with COVID-19. We encountered one such case where a 55-year-old male who tested positive for COVID-19 was noted to have, along with cough and vomiting, a new onset of left eyelid ptosis.

Can pneumonia cause Horner's syndrome?

We describe an immunocompetent patient with Horner syndrome secondary to invasive Blastomyces pneumonia and provide a review of the rare infectious etiologies of this syndrome. To our knowledge, this is the first published human case report of Horner syndrome secondary to Blastomyces pneumonia.

Which nerve damage causes Horner's syndrome?

Horner syndrome is caused by damage to a certain pathway in the sympathetic nervous system. 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.

How long does Horner's take to resolve?

Depending on the location of the damage and the underlying condition, if any, recovery time will vary. If the damage has no known cause, it is best to allow the disease resolve itself. This can take anywhere from 16 weeks to 6 months depending upon the severity of the symptoms.

What neurological disorder affects the face?

The most common cause of facial paralysis is Bell's palsy, which is thought to be a viral infection of the facial nerve, although the exact cause is not well known. Other causes of facial nerve paralysis include head trauma, parotid tumors, head or neck cancers, infections, brain tumors or stroke.

Can sinus infection cause Horner's syndrome?

A few cases of HS secondary to a sinus infection have been reported in the literature. To the authors' knowledge, there are only two case reports of individuals who developed sinusitis and Horner's syndrome. The present case is the first to present isolated HS features.

What test confirms Horner syndrome?

Apraclonidine testing can easily confirm the diagnosis of Horner's syndrome, but is unable to localize the lesion. Due to the long course of the oculosympathetic pathway from hypothalamus to the eye, there are multiple locations of potential pathology in Horner's syndrome.

Is Horner's syndrome life threatening?

The prompt diagnosis and determination of the etiology of Horner syndrome are of utmost importance, as the condition can result from many life-threatening systemic complications.

What are the signs of a serious ear infection?

Ear infections

• pain inside the ear (earache)
• a high temperature.
• difficulty hearing.
• discharge running out of the ear.
• a feeling of pressure or fullness inside the ear.
• itching and irritation in and around the ear.
• scaly skin in and around the ear.

What autoimmune disease affects the eyes and ears?

Cogan's syndrome is a rare autoimmune disease that primarily affects the eyes and inner ears, but can also cause inflammation of the blood vessels (vasculitis).

Can a blocked Eustachian tube cause eye problems?

Yes, congestion in the ear can affect vision due to the close connection between the inner ear and eye movement control, potentially causing symptoms like blurred vision or dizziness.
