  https://www.ncbi.nlm.nih.gov/books/NBK500000/

  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. […] Treatment is centered around the identification and appropriate management of the underlying cause. […] Therefore, treatment is centered around identifying and appropriate management of the underlying secondary cause. […] Treatment options are based on the diagnosis and management of the underlying cause. Timely diagnosis is of critical importance, followed by referral to an appropriate specialist. […] Whether surgical intervention is indicated and what type is appropriate largely depends on the cause of the disease. Surgical treatment options include the following: neurosurgical attention for aneurysm-related Horner syndrome, vascular surgical care for causes such as carotid artery dissection or aneurysm.

  Horner syndrome doesn’t occur on its own but develops as a result of another medical condition, such as a stroke, brain tumor, or spinal cord injury. The treatment is focused on resolving the underlying cause. […] The treatment for Horner syndrome varies based on the underlying cause. The treatment does not „cure” Horner syndrome but rather resolves or minimizes the underlying cause. […] Potential treatments may include: Anti-platelet drugs and minimally invasive treatments like angioplasty (for carotid artery problems), Clot-dissolving agents for specific types of stroke, Antibiotics or antiviral drugs for infectious causes, Immunosuppressant drugs for conditions like multiple sclerosis, Surgery, radiation, or chemotherapy for cancers.

• #8 Horner Syndrome – EyeWiki

  https://eyewiki.org/Horner_Syndrome

  Horner’s syndrome should be considered a neurological emergency and subject should be evaluated for dissection of the internal carotid artery as described below. These patients are at increased risk for cerebral infarction. […] The first step in the management of a patient with Horner’s syndrome is to perform appropriate studies to identify the cause. Imaging is often indicated in new onset Horner’s syndrome unless it occurs in the setting of trauma or surgical manipulation. High-yield sites of imaging can be identified based on accompanying signs and symptoms. These may include amongst others radiologic evaluation of brain, cervical spinal cord, cerebral vasculature, head, neck and thorax. Treatment depends on the etiology of Horner’s syndrome. […] Once life-threatening conditions have been ruled out and the patient is stable, visually symptomatic ptosis can be managed surgically. The surgical approach varies on surgeon preference. Since characteristically the levator palpebrae function is normal in Horner’s syndrome, surgery typically involves strengthening the action of the levator muscle. The approach may include either aponeurotic advancement or Müller’s muscle- conjunctival resection.

  Horner syndrome is a rare neurologic disorder that can arise from severe neurologic and systemic conditions, which may require immediate diagnosis with radiologic imaging and treatment with antiplatelet and anticoagulant therapy. […] Due to possible life-threatening complications that can arise in patients with Horner syndrome, clinicians must have a thorough understanding of the condition, appropriate treatment, and management modalities. […] Understanding the need for immediate testing to determine the underlying etiology of Horner syndrome can help prevent a decrease in a patients vision or quality of life, and in some cases, prevent death.

  https://app.pulsenotes.com/medicine/neurology/notes/horner-s-syndrome

  The treatment of Horners syndrome is directed towards the underlying cause. […] It is most important to remember that an acute, painful Horners syndrome is a neurological emergency that requires urgent assessment for a carotid dissection. These patients need urgent neuroimaging and discussion with a hyperacute stroke unit (HASU). If clinical features of stroke are already present they usually require urgent transfer to the hyperacute stroke unit. […] If dissection has led to stroke, these patients may be suitable for thrombolysis or mechanical therapies if they meet eligibility criteria. This should be decided by a stroke specialist in a stroke centre. In the absence of acute stroke, patients may be treated with anti-platelets or anticoagulation depending on the vessels involved (e.g. intracranial versus extracranial).

  In this patients case, an immediate neurologic evaluation was appropriate due to the acute and painful nature of her presentation. Ultimately, her Horner syndrome was determined to result from an internal carotid artery dissection. […] Due to the potential complications that can arise, carotid artery dissections require prompt treatment with antithrombotic therapy for 3 to 6 months to prevent carotid artery occlusion, which can result in a hemispheric cerebrovascular accident or TIAs. […] The options for antithrombotic therapy include anticoagulants, such as warfarin, and antiplatelets, such as aspirin. Studies have found similar rates of recurrent ischemic strokes in treatment with anticoagulants compared with antiplatelets, so both are reasonable therapeutic options. […] Following a carotid artery dissection diagnosis, patients should be evaluated by neurology to minimize other cardiovascular risk factors and prevent other complications.

  New onset right ptosis (with miosis) in a patient who presented with Horners syndrome secondary to a Pancoast tumor. […] The diagnosis and localization of Horners syndrome can be accomplished with pharmacological testing. […] Cocaine is a sympathomimetic drug which acts indirectly to prevent reuptake of endogenously released norepinephrine from the sympathetic nerve terminal. […] Topically applied cocaine identifies Horners syndrome, but does not indicate where the problem lies within the sympathetic three-neuron arc. […] Unfortunately, these drugs (cocaine and hydroxyamphetamine) are not available for clinical practice; however, it appears that the intraocular pressure lowering drug apraclonidine (0.5% and 1% Iopidine, Alcon) is a viable option. […] Pupil dilation in suspected cases of Horners syndrome is considered diagnostic. […] It appears that the most readily available agent, Iopidine 0.5%, is at least as sensitive and specific in the diagnosis of Horners syndrome as cocaine.

  Horner syndrome was first demonstrated by Parkinson in 1929. Presently, the treatment of the disease is primarily based on etiological treatment. Certain curative effects can be achieved by treating the primary conditions that cause Horners current syndrome, such as blood vessels, mass, trauma, and surgery. The clinical Horner syndrome is characterized by ptosis; mydriasis; partial sweating or no sweating on the affected side; retraction of the eyeball on the affected side, which can be cured after conservative treatment. […] The use of neurotrophic drugs and hormone therapy can be effective for some patients. The main manifestations after the injury are ptosis of the upper eyelid, miosis, and retraction of the eye on the affected side. […] Once the clinical manifestations of Horner syndrome are found, it is recommended to use neurotrophic drugs and give an appropriate amount of glucocorticoids, supplemented by traditional Chinese medicine acupuncture. The disease can be cured with conservative treatment. […] Generally, Horner syndrome after surgery for differentiated thyroid cancer is curable with conservative treatment, and this complication is minimized during surgery.

  Most cases of Horner’s syndrome resolve spontaneously; however, it is important to treat any underlying disease. There are several diagnostic tests that will determine if there is an underlying cause in your pet, including an eye and ear exam, X-rays (radiographs) of the skull and chest, and possibly advanced imaging such as CT scans or MRIs. Pharmacologic tests may include phenylephrine drops placed in the affected eye to help localize the source of the problem.
