NYSTAGMUS: Symptoms, causes, diagnosis and treatment.


nystagmus is the condition of the eye characterized by rapid ocular movements. It does not always cause any remarkable symptom, but it can be associated with such problems as problems with dizziness and vision.A series of different neurological diseases can cause Nystagmo. Nistagmo is generally determined during a physical examination, which includes an ocular evaluation.This can be an early sign of a neurological state, such as multiple sclerosis (MS) or can be developed as a neurological disease already installed. It is possible that it must be treated to help reduce its effects of nystagmo and / or accompaniment.Having a large part of the time, the medical or surgical management of the base cause is also necessary.

Nystagmo usually affects both eyes , But rare can affect one eye.Confident movements are generally not present all the time, and Nystagmus is usually more visible when seen in one direction or another. In severe cases, eye consumption may be present all the time, even when it looks forward (not separated).

Nystagmus seems a fast, rhythmic, horizontal ocular movement (side by side). It can occur vertical (up and down) or a rotating nystagmus (mobile circle), but these templates are not common.

General symptoms Adults purchased by NYSTAGMUS (which differ from NYSTAGMUS Congenital) Includes:

  • dizziness
  • dizziness (feeling,that the room rotates or what it rotates)
  • reduced balance
  • nausea or vomiting
  • double or blurred
  • headache,Irritation
  • Standing it that the visible objects jump rhythmically

you can experience all or some of them symptoms when It has a nystagmus.Often, however, when Nystagmo has been present for a long time, symptoms are not obvious.

sometimes nystagmus can be so serious that it affects your balance.Sudden episodes (for example, when induced to spin) can make dizziness that you could fall and suffer.

Related symptoms

If your nystagmus is caused by neurological state, you can also experience other effects.The associated symptoms are not necessarily caused by Nystagmo, and do not cause Nistagmo. In its place, they are generally caused by the disease caused by Nystagmo (for example, a brain tumor).

Physical signs that may arise from NYSTAGMUS,Include:

  • Weakness on one side of the body
  • numbness or reduced sensation on one side of the body
  • Balance strongly broken
  • Themes (trembling or body shaking)
  • plane with discount
  • Deficiency Vision
  • Petelidos Doopy
  • Memory loss

If you have signs of nystagmus , you need to receive medical care.The neurological problems that are generally associated with eyes for eyes can deteriorate gradually if they are not treated.


NYSTAGMUS is a symptom of some neurological diseases and states that include the internal ear. There are many neurological diseases that may be associated with eyes for eyes.Driving from the conditions that cause Nistagmuses to be severe and potentially fatal, as a book. Other are not related to serious health risks, as a lazy eye .

Common risk factors

CONDITIONS They increase their risk of nystagmus, do not always create it. Done, Nystagmo is a relatively unusual sign of neurological or internal ear disease.

Turning : spinning around the circle for a few minutes, and then stopping can cause a short period of nystagmus affects In both eyes.Usually, it is harmless, but you can feel dizziness for a few minutes or even all day after that.

Strabismus (lazy eye) : The congenital defect (from birth) can lead to eye displacement.This can cause an obvious labeling effect described as a lazy eye. The odd nystagm can occur with the lazy eye, especially when you look to the left or right.

Mnirires EMACHION : A condition characterized by episodes of heavy dizziness and possible loss of hearing, MNIRA’s disease is often associated with rhythmic eyes for eyes, especially During the attacks.

Scattered sclerosis (MS) : This condition can cause several neurological symptoms, since it can affect several areas of the brain , / A>, and / or the visual nerve (nerve that controls vision).MS can lead to a constant or intermittent episode of nystagmo in one or both eyes.

Brain tumor : primary brain tumor (tumor, starting in the brain) or metastatic cancer from other places In the body you can invade or enter the cranial nerves , brains,O The cerebellum causes the development of Nistagmo.

Labirintitis : Inflammation of the internal ear is described as a labyrinthitis.This can occur due to infection or inflammatory disease, or it can be idiopathically (without identifiable cause). This condition can cause deep dizziness, nausea and vomiting, and its exhibition of eye exams can show NYSTAGMUS.As a general rule, labyrinthitis is characterized by severe symptoms, but it is generally not associated with serious or potentially fatal health risks.

Hind : Interruption in blood flow in the brain can cause brain damage. At rare cases, stroke can lead to Nistagmo.

Paranoplastic syndromes : Various types of cancer can form antibodies (immune cells), which attacked people their own body causing a paranoplastic syndrome, a Rare side of cancer effect.Nystagmo is one of the common symptoms of Paranoplacas syndromes. The ovarian’s adrenal glands and rakoki cancer are examples of cancer that can have this effect.

congenital defect : Some children are born with Nistagmo, and can start during childhood. The benefit can also arise during a subsequent childhood due to the hereditary state.Nistagmo’s childhood can be developed as a result of hocular albinism ,A genetic disorder associated with an X link characterized by the deteriorated view and the reduction of the pigment in IRIS (Color of the eye around a student) of the affected men. .Examples include dilantin (phenytoin), tegretol (carbamazepine) and barbiturates. These medications interfere with nerve functions, and Nistagmus should be broken down after the medication is metabolized from the body.

Alcohol : Alcoholic poisoning can temporarily affect the nerves that control balance, which led to coordination and nystagmus problems.

Trauma : The injury of the trauma can cause damage to the brain, nerves or muscles that control the movement of the eyes, which leads to a nasagmus.

Eye Motion Management

There are several areas of the brain and the internal ear, which are associated with the coordination of the Eye of the movement.Continuous injuries or temporary deficit involving any of these areas can interfere with normal eye movements, causing a series of potential vision and / or balance problems, including nystagms.

Nystagmus may be the result of deteriorating any of the following structures:

: The cerebellum is the area of your brain that controls the balance.The damage to the cerebellum, for example, of a tumor or stroke, can cause Nystagmo.In addition, antibodies in Paranoplacas syndromes cause Nistagmo, pointing to a cerebellum.

Cranial nerves : There are three pairs of cranial nerves that control the muscles of the ocular movement (each eye is controlled by a nerve of each pair). The damage to these nerves can interfere In the muscles of the eye, calling Nystagmus.

BRANSTONE : The cranial nerve fibers and brain nerve fibers work even though the brain, the brain area connecting the brain with a spinal cord.For this reason, the disease, which includes a cerebral (for example, hemorrhage or stroke), can cause Nistagmo.

Internal ear : The internal ear contains many small structures that control the audience and help the intermediate balance. Defending, infection and tumors associated with the inner ear can cause Nystagmo.


Even if you have many related symptoms, Nystagmus is usually unnoticed in daily life. It is unlikely that you notify your own movements in the eyes of your eyes.In the mirror it is very difficult to see your nystagmo in the mirror, because the movements are usually more intense when you look at the side. Sometimes, family or friends can notice your eyes when they look at you.

Nystagmus is generally determined in the Health Provider Office during a medical examination. Your practitioner can review NYSTAGMUS when performing neurological exams during your annual physicist.His muscles for the eye will be verified , as he is asked to look at each side as with both eyes, and hold his gaze for a few seconds.Call a doctor, you will also notice NYSTAGMUS during the usual ocular exam (for example, for your lenses or contact lenses).

If you have NYSTAGMUS, your medical team will do more tests To determine the cause and see if you have alarming complications.

Diagnostic exams that can be included:

    • Eye exam : There are several steps in the eye exam.Your health care provider will review your visual sharpness (how well you can see objects closely and distant), usually with death. It will also have an exam that includes a distance from the distance between your students.This test can appreciate any difference in movement of the eye between the eyes, and can help determine the lazy eye.Your medical care can measure the speed and address of eye movements, and this evaluation may include video of your eye movements. . Determine the structural problems in the brain and in the inner ear, such as tumors and blows.These conditions can affect the cerebellum function, the cranial nerves or the inner ear, which leads to Nistagmo.

    • ElectronyStagMogry (Eng) : This diagnostic study is used to evaluate dizziness , dizziness or nastagm.ENG is a non-invasive test that objectively measures the function of oculot and vestibular nerves, and can help determine accurately if one of these nerves is disturbed.


    There are several procedures used to reduce the effects of NistagmoMedications can be prescribed to specifically reduce eye movement for eyes. Sometimes treatment is required to help reduce nausea and tied dizziness.

    Advanced If you have a neurological state that forces you to have NYSTAGMUS, you may need to use rehabilitation therapy to administer your neurological disease.

    See correction

If the vision deficit makes NYSTAGMUS, it is It is possible that you need to use corrective lenses helps fix your vision. In some situations, the surgical vision correction is considered the best option.

Eye control

The recipes used to reduce nystagmus include the Eyeled fire (amifampridine), Laurus (Baclofen), Clonopin (Clonazepam) and Neurontin (Gabapentina ). These medications can temporarily reduce your nystagmo, but you should not cure it.

Symptomatic therapies

If dizziness, nausea and / or vomiting You are problematic for you your health care provider may recommend excessive or prescribed therapy to help facilitate these effects.

Medical control of neurological diseases

You may need medical therapy to treat the cause of your nystagmus.This may include the modification of disease therapy for MS management, anti-inflammatory medicine to control MNIR or antibiotics for the treatment of infection of internal ears.

BOTOX (botuline toxin) It can be used to attenuate and relax the muscles of the eyes.This is not the same as Botox cosmetic, and it requires a lot of care to avoid causing eye damage and close structures.

The botulinine toxin weakens the muscles, and when used to treat the nystagma, it reduces the compensatory nystagmus, which occurs when the muscles of the eyes do not have the same force.

In some situations, an eye operation can restore muscle defects that cause Nistagmo. You may need treatment for a brain tumor or a tumor of the internal ears.Dental treatment approaches include surgical removal, radiotherapy and / or chemotherapy.


Sometimes therapy with rehabilitation methods can be effective as a way to help strengthen the muscles EyeIt can facilitate the problem if the easy weakness of the muscles of the eyes is the cause of your nystagma.

Word of obtaining information medications

Nystagmo is often a symptom of neurological disease.If your eye is trembling, you may need to be treated.

sometimes nystagmus does not cause any symptoms in anyone and can be detected at random (randomly) when your health care provider considers your eyes.There are times when Nystagmus is the first key that has a neurological disorder. In these cases, you may need a complete medical evaluation to determine the cause of your eye.The treatment of neurological states that call NYSTAGMUS is usually necessary.
