What causes nystagmus?

Nystagmus is common in congenital and is usually accompanied by strabismus and amblyopia. It is recommended that you go to the eye clinic for a detailed examination as soon as possible to detect it early and restore your vision as soon as possible. Congenital nystagmus is the possibility of shaking the head unconsciously, usually this symptom is mostly caused by central nystagmus, usually due to brain stem damage or brain disease, it is recommended to go to the hospital for a detailed examination.

Involuntary shaking of the eyes from side to side, considered to be caused by horizontal nystagmus, is a congenital developmental abnormality, and it is necessary to check whether there is a median zone, that is, whether the tremor can be reduced when the eye turns in a certain direction, and if so, it can be surgically reduced**. Eye tremor, this symptom is relatively rare in daily life, generally caused by some diseases of the nervous system, the impact of this situation on vision is very large, if not in time, it may cause insomnia, and generally cause the sequelae of shaking head, so only through surgery to correct can be recovered. Children with nystagmus should not eat partially, and should pay special attention to the intake of vitamin B (embryo rice, cereal yeast).

You can eat more foods containing vitamin A, such as camellia, mustard greens, bitter gourd, carrots, lemon seeds, figs, animal liver, herring, white fish, mussel meat, and snails. Some vegetables in the daily diet are very beneficial for the maintenance of the eyes and other physiological functions. Such as spinach, tomatoes, carrots, etc.

Congenital nystagmus is mainly caused by lesions in the eye itself. For example, high refractive error at night, or congenital cataracts, and glaucoma can cause refractive interstitial opacity, resulting in abnormal conditions in the eyes and nystagmus.

Nystagmus is an involuntary, rhythmic, pendulum-like or beating-like oscillation of the eyeball. The main causes of nystagmus are early eye motor dysplasia, such as congenital cataracts, which cause nystagmus, as well as family genetic history, Down syndrome, brain damage, or lesions, such as inflammation of the brain, tumors, degeneration, trauma, and vascular diseases, which may cause nystagmus. In addition, nystagmus can be caused by eye disease or eye dysfunction, degenerative changes of the optic nerve, severe astigmatism, high myopia, physical diseases, multi-site sclerosis, stroke, and severe ear inflammation.

Some poisonings can also cause nystagmus, such as sedative poisoning, antipsychotic poisoning, bromide poisoning, etc., alcoholism, albinism are also one of the causes of nystagmus. Sometimes nystagmus is not defined** and may also be affected by mental and physical strength, such as stress, fatigue or nervousness.

It is normal for the eyes to move from side to side in everyday life when people are conscious. However, there are also some people who involuntarily move their eyes back and forth, and the eyes are rhythmic when moving, either rotating or vertical. In fact, this condition is not normal, it belongs to nystagmus, so what causes nystagmus?

1. Retinal or refractive media lesions.

These lesions often cause cataracts, refractive errors, choroiditis, and some patients will suffer from the disease at an early age, although they will have amblyopia symptoms, but still preserve their vision, and these patients often cannot fix the fixation of the eyeball, and then develop nystagmus symptoms. If the patient is in a poor light environment for a long time, he will also have vision fixation disorder and wobble tremor.

2. Vestibular labyrinth lesions.

If a patient has damage to the vestibular nerve or vestibular nerve nucleus, the vestibular nerve response will be too high or too low, and these adverse symptoms can cause nystagmus. Acute vestibular labyrinth lesions cause contralateral tremor of the eyeball, accompanied by tinnitus, nausea and vomiting. If the labyrinth lesion is chronic, the patient will tremor toward the affected side.

3. Central lesions.

Nystagmus is caused when lesions occur in the vestibular nucleus that connect the brainstem or cerebellum, and there are many tremor features caused by central nervous disease. If it is only a brainstem lesion, it will produce unilateral tremor and will be predominantly vertical tremor, whereas demyelinating lesions will cause upward tremor. However, central nystagmus is generally not wobbly and is not prone to vertigo or hearing impairment.

4. Genetic and other pathologies.

Some children will have symptoms of nystagmus soon after birth, the cause of this lesion is unknown, but it is related to genetic factors, generally there are patients with congenital nystagmus in the family, then the possibility of this disease in later generations is relatively high, and often the nystagmus caused by this genetic factor is lifelong. In addition, drug poisoning, hysteria, etc. can also cause nystagmus.

Nystagmus is an involuntary, rhythmic, back-and-forth eye movement. It is often caused by diseases of the visual system, extraocular muscles, labyrinth of the inner ear, and the central nervous system. Nystagmus is one of the most serious eye diseases, which belongs to refractory amblyopia, and is divided into horizontal tremor and vertical tremor.

Nystagmus involves ophthalmology, otology, neurology and is a symptom of a disease that often occurs in people with ophthalmic diseases called oculogenic nystagmus. Such as congenital cataract, congenital corneal opacity, congenital vitreous opacity, congenital glaucoma, congenital aniridia, total color blindness, albinism. There is also a large magnitude of nystagmus, which is common in children with strabismus, amblyopia, high farsightedness, myopia, astigmatism, and mixed astigmatism.

There is also nystagmus that is not associated with an ophthalmic condition and is called non-ophthalmic nystagmus.

What are the causes of nystagmus?

Oculogenic nystagmus.

Common ** are congenital eye malformations, ocular neuromuscular dysplasia, cataracts, total color blindness, macular lesions, etc.

Otogenic nystagmus (vestibular nystagmus).

It is commonly found in Meniere's syndrome, otitis media, labyrinthitis , acute vestibular impairment, etc.

Central nystagmus.

It can be seen in encephalitis, brain tumors, cerebrovascular diseases, traumatic brain injury, encephalopathy, ataxia, stroke or multiple sclerosis.

Other. It may be related to heredity, with X-linked recessive inheritance being the most common, which manifests as a parent with the disease, and children are at high risk of developing the disease.

Some nystagmus can be caused by drugs or toxic substances (eg, opioids, barbiturates, alcohol, lead, etc.).

Some special occupations, such as coal miners and train dispatchers, are prone to occupational nystagmus.

Some patients with abnormal thyroid function may have neurological symptoms such as nystagmus.

How exactly does nystagmus form?A: The causes of nystagmus are mainly caused by hypoxic damage to the brain, as well as developmental abnormalities

Especially during the mother's pregnancy and childbirth, due to intrauterine hypoxia, the patient's brain is deprived, the labor process is prolonged during labor, dystocia or birth trauma, etc., can cause nystagmusOthers are caused by a disease or a parental condition, such as albinism

99% of cases are congenital nystagmus1. Pay attention to proper rest: Because many people are under great pressure to study or work, they often sit at the table for several hours, and excessive eye fatigue leads to muscle spasms and nystagmus, so it is necessary to let the eyes rest for a while every half an hour

2. Clean and hygienic eyes: Many people often like to rub their eyes with their hands to relieve fatigue or dryness, but there are more bacteria on their hands, which can easily enter the eyes and cause eye diseases, so it is necessary to cultivate good hygiene habits and not rub their eyes with their hands.

Nystagmus is an involuntary and rhythmic swing of the eye movement disease, once this disease appears, the patient will be complicated by amblyopia, lateral vision and strabismus and other complications, if not in time, it will seriously affect the normal life and work of the patient. So what causes eye shocks?

1. Lesions in the retina or refractive medium may lead to nystagmus. If the patient has been born with cataract and choroiditis and central cornea, then the patient will have opaque spots or refractive errors that cause the patient to develop amblyopia, in which case the patient still retains part of the vision, but the eyeball is always unable to be fixed, which will also cause nystagmus.

2. Some nystagmus patients are due to being in a place where the light is not very good for a long time, so that after a long time, the patient will have eye fixation disorder, which will also lead to nystagmus.

3. Lesions in the center can also lead to nystagmus, because after the lesion occurs in the center, it will cause the symptoms of horizontal, rotational or vertical tremor, which is mainly a characteristic of brainstem diseases, and when the brainstem is compressed, distorted and deformed or poisoned by antispasmodic drugs, it can also lead to vertical tremor, which is one of the causes of nystagmus.

4. The occurrence of nystagmus is related to genetic factors, this form of inheritance is mainly autosomal dominant or recessive inheritance, such patients generally have a slight eye swing when they are at rest, and when the patient looks from any direction, this tremor will increase, and the patient will also be accompanied by the phenomenon of head vibration or point movement, but the patient has no conscious symptoms.

What disease causes nystagmus? This tremor must be caused by a variety of causes, well, a lot of diseases.

Nystagmus is an involuntary, rhythmic, pendulum-like or throbbing oscillation of the eyeball. In general, the main causes of nystagmus are: early oculomotor dysplasia (congenital cataract), inheritance between family members, Down syndrome, brain damage or lesions (inflammation, tumors, degeneration, trauma, vascular diseases), eye diseases or eye dysfunction (optic nerve degeneration, severe astigmatism, high myopia), physical diseases (multisite sclerosis, stroke, severe ear inflammation), poisoning (all sedatives, antispasmodics, bromide, etc.), alcoholism, albinism, etc.

Sometimes nystagmus is not defined** and may also be affected by mental or physical strength, such as stress, fatigue or nervousness.

Analysis: The first of the nystagmus are: congenital nystagmus, which is due to genetics or unexplained birth.

It is caused by diseases such as cataracts, amblyopia, etc. Extraocular muscle paralysis can also cause nystagmus. Lesions of the labyrinth of the inner ear and the central nervous system can also cause nystagmus.

The causes of eyelid tremor are:1Ophthalmic nystagmus refers to nystagmus caused by macular central visual impairment, which makes it difficult for fixation reflexes to form (1) physiological fixation nystagmus, including oblique nystagmus, visual dynamic nystagmus, recessive nystagmus, etc.

2) Pathological fixed nystagmus, including blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc. 2.Vestibular nystagmus3.

Central nystagmus4. Congenital idiopathic nystagmus, your current condition, I recommend you to go to a specialized eye hospital for a detailed examination and**. For congenital essential nystagmus, surgery** may be performed to move the resting eye forward to improve vision and reduce or suppress the occurrence of nystagmus.

Congenital essential nystagmus can be surgically moved** to the resting eye to improve vision and reduce or suppress the appearance of nystagmus.

In addition to congenital dysplasia, nystagmus can also be caused by some ophthalmic diseases or other diseases, such as cataracts, albinism, etc. There is also nystagmus caused by working in the dark for a long time, which leads to a decrease in the ability to fixate on the macula of the eye. There are also some central diseases, such as diseases in the brain.

Whatever the cause of nystagmus, it is necessary to **.

If you have nystagmus, you should still think that there is a problem with the optic nerve. In addition, if the eyesight is not good, you need to check the fundus to see if there are any lesions. In this case, it is best to go to the ophthalmology department of the hospital for a formal examination, clarify the reason, and eat according to the situation.

Patients with nystagmus may have congenital amblyopia, congenital cataracts, severe refractive errors and other diseases, or they may be in a place with poor light for a long time, or they may have central nervous system lesions. If there is nystagmus, it is necessary to go to the hospital for examination in time to prevent the symptoms of nystagmus from becoming more serious and affecting daily life.

The first types of nystagmus are: congenital nystagmus, which is due to genetics or unexplained birth. It is caused by diseases such as cataracts, amblyopia, etc.

Extraocular muscle paralysis can also cause nystagmus. Lesions of the labyrinth of the inner ear and the central nervous system can also cause nystagmus.

Maystagmus may be a very unfamiliar disease for many people, but in the literal sense we can understand that it is the flutter of the eyeball. Nystagmus refers to the involuntary, rhythmic round-trip movement of the two eyes, according to the rhythm of tremor, it can be divided into beating type, pendulum type, of which the beating type is the most, tremor is composed of fast phase and slow phase two phases. The pendulum type is rare, the tremor has no fast and slow phases, and the swing speed of the two phases is basically the same.

Nystagmus is now circulating that there is no cure, wrong! Because 99% of medicine is now Western medicine, nystagmus is a neurological cause, and it can't detect anything, Western medicine is not, and Western medicine can only detect diseases. 99% of patients are congenital nystagmus, tremor can be completely cured, vision needs to be slowly restored later, if the vision is simply restored, it is impossible to have an effect, the so-called amblyopia, flash, photophobia and other symptoms are caused by tremor, only the tremor is cured, the others can restore everything to normal.

Patients with nystagmus have a great impact on people's lives, typical reading and learning are definitely not good, it is difficult to work and find employment, and there is no center point for seeing objects in life. For patients whose condition is getting worse step by step, it will also cause a sharp decline in vision, narrowing of the visual field, which will lead to major optic nerve disease, and most patients will be blind. Parents and individual patients must pay attention to it.

Nystagmus, or nystagmus, is an involuntary, rhythmic, back-and-forth eye movement.

Details: Horizontal tremor of the left and right of the eye"Pendulum nystagmus"Pendulum nystagmus"The oscillation of the eyeball from left to right and from right to left.

The swing of the eyeball is like a pendulum, there is no fast phase and no slow phase. Its velocity and amplitude are equal. The eyeballs tremble and shake from side to side, varying in frequency. Sometimes torticollis is present, and the eyeball is leaning to the side to look at an object.

Vertical tremor up and down "Throbbing tremor" The eyeball beats from top to bottom and beats from bottom to top.

Eyeballs up and down tremors, throbbing, etc. The eyeball moves back and forth at a marked different speed, and when the eye slowly turns in the other direction to a certain extent, it suddenly returns in a rapid movement.

Rotational tremor"Rotational tremor"Rotational tremor"The eyeball moves like a circle, but it is not a 360-degree rotation, which is relatively rare.

Clockwise and counterclockwise rotational tremor (the eyes bobbing back and forth in circles like a garden, sometimes 90 degrees, sometimes 120 degrees, etc.), nystagmus.
