What are the root causes of nystagmus?

There are different types of nystagmus causes, mainly seen in the following:

1. Congenital essential nystagmus: also known as congenital motor nystagmus, which is not clear at present, and no intracranial abnormalities have been found. Its clinical manifestations are throbbing tremor, which remains unchanged for life, and the patient has a median and compensated cephalic position;

2. Oculogenic nystagmus: pendulum tremor due to poor vision can be caused by congenital cataract, lowe syndrome, albinism and other ophthalmic diseases. In addition, there are nystagmus associated with strabismus, such as nystagmus block syndrome, in which children will have esotropia;

3. Central nystagmus: mostly manifested as simple horizontal, vertical or rotating nystagmus, such as intraventricular hemorrhage after birth, acquired nystagmus can be caused by intracranial tumor compression. Certain metabolic disorders affect brain function, such as lipofuscinosis, and vision loss accompanied by nystagmus;

4. Vestibular nystagmus: mostly caused by acute labyrinthitis, which can be accompanied by vertigo;

5. Other reasons: such as infant nodding spasms, which are more common in infants from 4 months to 1 year old, and less common after 3 years old, as well as toxic nystagmus from drugs, such as organophosphate poisoning.

If you experience acquired nystagmus, it is advisable to seek medical attention as soon as possible.

Retinal or refractive media lesions: In juvenile amblyopia due to congenital cataracts, choroiditis, opaque spots in the central cornea, or refractive errors, partial vision is preserved, but oscillating nystagmus can occur because the eye cannot fix fixation. Prolonged exposure to poor light may lead to impaired vision fixation, and a wobble tremor called "occupational or miner" nystagmus may occur, and may also be accompanied by head tremor and levator palpebrae spasm.

Central lesions: Central lesions can cause horizontal, rotational, or vertical tremor, which some have called characteristic of brainstem disorders, but can also occur when the brainstem is compressed, distorted, or poisoned by antispasmodic drugs. Predominantly abrupt tremor.

Congenital and familial nystagmus: Usually occurs soon after birth and lasts for life. The form of inheritance is autosomal dominant or recessive.

The patient's eyes are at rest when there is a slight wobble tremor, and the tremor increases in any direction, which may be accompanied by head vibration or pointing, but the patient has no self-conscious symptoms, and the nystagmus is not known in the microscope, but the beating of the eyes of other congenital nystagmus patients can be found (due to the different frequencies of the two). Nystagmus is divided into two categories: physiological and pathological. 1. Physiological nystagmus occurs in normal eyes, such as optokinetic nystagmus when the eyes are extremely sideways and the black and white streaks are turned to turn the drum.

2. Pathological nystagmus can be divided into: 1. Congenital 2 It generally occurs in children with congenital eye diseases, such as congenital eye malformations, albinism, cataracts, or visual diseases caused by macular damage. 2. Visual impairment in infancy and early childhood, that is, high visual loss.

3. Extraocular muscle paresis. 4. Inner ear labyrinth lesions. 5. Central lesions are often cerebellar lesions, and a few are lesions of the vestibular nucleus and brain.

6. Vestibular is induced by vestibular nerve nucleus lesions and manifests as vertical tremor. 7. Acquired gains.

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.

The main causes of nystagmus are as follows:

1.Genetic factors, some congenital nystagmus are mostly thought to be caused by genetic factors.

2.Eye diseases, such as macular lesions and ocular neuromuscular dysplasia, can cause nystagmus.

3.Inner ear diseases, such as labyrinthitis and otitis media, can cause damage to the receptors of the inner ear, which in turn can cause nystagmus.

4.Neurological disorders, commonly found in cerebral infarction, brainstem or cerebellar disorders.

5.Drugs or alcohol, such as anti-seizure medications, sedatives, or alcoholism, can cause nystagmus by impairing local brain functions.

Nystagmus may occur due to changes in the retina or refractive mediator. 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.

There are many causes of nystagmus. These include congenital nystagmus, as well as cataracts, macular degeneration, etc. Central disease can also cause this condition in children.

Most of the nystagmus is a congenital disease, because the child's eyeball is in a state of tremor, the eye cannot fix, and there will be discomfort and poor vision for a long time. In view of the current situation, it is recommended to take the child to the ophthalmology department of the hospital to find an experienced doctor to understand the details of the child's nystagmus, whether there is amblyopia, what is the current vision, whether it is possible to wear glasses for correction, etc., so that the problem can be solved.

Nystagmus may be caused by congenital dysplasia, and when nystagmus occurs, it is usually accompanied by eye abnormalities such as low vision, strabismus, and amblyopia. In addition, nystagmus may also be caused by neurological pathway lesions in the brain caused by cardiovascular and cerebrovascular diseases or tumor trauma.

There are many reasons for the appearance of nystagmus disease, most of the patients, the retina is congenital lesions, if there is congenital cataract or choroiditis, we must take a reasonable ** in time, otherwise it is easy to lead to the appearance of nystagmus disease, affecting the patient's future life.

Oculogenic nystagmus.

Common ** are congenital eye malformations, ocular neuromuscular dysplasia, cataracts, panchromatopsis, macular lesions, etc.

Otogenic nystagmus (vestibular nystagmus).

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

Central nystagmus.

It can be seen in encephalitis, brain tumor, cerebrovascular disease, traumatic brain injury, brain**, ataxia, stroke or multiple sclerosis.

a) Oculogenic nystagmus.

1. Visual impairment, congenital amblyopia, severe refractive error, congenital cataract, color blindness, high myopia, albinism, etc.

2. Extraocular muscle paralysis.

3. Congenital or hereditary nystagmus, the eyeball is in a persistent horizontal swinging movement, regardless of fast or slow phase.

2) Vestibular nystagmus.

It is commonly found in Meniere's syndrome, otitis media, labyrinthitis, acute vestibular dysfunction, pontine cerebellar angle tumors, etc.

3) Central nystagmus.

1. There are many bulbar lesions.

Rotational spontaneous nystagmus. It is seen in syringomyelia, vascular lesions, tumors, etc.

2. Pontine lesions.

Horizontal nystagmus is common. It is seen in tumors, vascular lesions, multiple sclerosis, etc.

3. Midbrain lesions.

Mostly vertical nystagmus. It is seen in vascular disease, encephalitis, trauma, etc. If the lesion is near the oculomotor nucleus at the level of the superior thalamus of the midbrain, sunken nystagmus may be seen, and radial beating and sunken eyes may occur when the eye is fixed upward.

4. Cerebellar lesions.

Usually horizontal nystagmus. It is seen in cerebellar tumors, cerebellar vascular lesions, degenerative lesions, etc.

5. Lesions above the brainstem.

Spontaneous nystagmus and positional nystagmus may be seen in prefrontal lobe lesions.

6. Medial longitudinal tract lesions.

Dissociative nystagmus may occur.

iv) Toxic nystagmus.

It can be caused by drugs or poisons such as opioids, barbiturates, alcohol, lead poisoning, etc. The nature of nystagmus is similar to that of cerebellar nystagmus.

5) Other reasons.

1. Latent nystagmus: the cause is unknown.

2. Occupational: seen in coal miners, train scheduling, etc.

3. Cervical spinal cord lesions: Upper cervical spinal cord lesions are common, which may be related to damage to the medial longitudinal tract or vestibulospinal tract.

Congenital factors. Congenital anomalies or genetic factors can cause congenital or hereditary nystagmus, in which the eye moves horizontally for a long time, regardless of whether it is fast or slow.

2. Ocular lesions.

For example, congenital amblyopia, severe refractive error, congenital cataract, color blindness, high myopia, visual impairment caused by albinism, extraocular muscle paralysis and other ocular lesions can lead to the appearance of ocular nystagmus.

Nystagmus is an involuntary rhythmic movement of the eyeball, and its causes are more common in the eyes themselves, central nervous system or congenital factors, and some reasons are not clear. It is recommended to go to some regular hospitals

Nystagmus is an involuntary rhythmic reciprocating oscillation or beating of the eyeball, which is caused by many reasons, basically a handful of ocular nystagmus, ocular muscle, nystagmus, vestibular nystagmus and unexplained nystagmus.

Nystagmus is not a simple disease, it is a kind of low vision caused by various reasons, causing the eyes to be unable to see. Because when our eyeball looks at objects, it forms this kind of vision through the macula. This is what the patient with nystagmus says, and the eyeball has been in this state of trembling, that is, it is impossible to see, and if it is unable to take care of it, it is a relatively low vision that causes this kind of vision, that is, it mainly means this.

Nystagmus**:1Ophthalmic nystagmus refers to visual disturbance in the center of the macula, which is caused by difficulty forming the fixation reflex.

1) Physiological fixation nystagmus includes oblique nystagmus, visuodynamic nystagmus and recessive nystagmus. (2) Pathological fixation nystagmus includes blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc. 2.

Vestibular nystagmus. 3.Central nystagmus.

4.Congenital idiopathic nystagmus.

What is the root cause of nystagmus? The root cause of nystagmus is nerve problems, so it is said that the nystagmus is caused by nerve problems, so it is not easy to say that this phenomenon is not easy.

Most of them are due to congenital genetic factors, mainly efferent nerve dysfunction.

What is the root cause of nystagmus? I think the root cause of nystagmus is the optic nerve.

What is the root cause of nystagmus? The root cause of such a long eyeball is eye spasm or other eye problems.

Hello! Nystagmus** may be early movement disorders, Down syndrome, brain damage or lesions, eye disease or ocular dysfunction, degenerative changes of the optic nerve, etc.

Hello, what I personally think is the best for you. The specific medical institution needs to be observed and considered by yourself.

Bulbar tremor is mostly due to congenital genetic factors, mainly efferent nerve dysfunction. This condition is often combined with nystagmus block syndrome, and the main way is to choose to wear prisms. In addition, patients with compensated cephalic position can choose to undergo surgery, and most of them do not have good results.

The main causes of nystagmus include visual impairment caused by congenital eye malformations, albinism, cataracts, total color blindness, macular damage, etc., and most of them have poor vision due to the lack of fixed fixation on the target.

Nystagmus mainly refers to the uncontrolled voluntary movement of the eyeball, and now the incidence of nystagmus is very high, it is a common and frequent disease in ophthalmology outpatient clinics, nystagmus is divided into congenital nystagmus and acquired nystagmus, congenital nystagmus often has a lot to do with heredity. Because of the deficit of ocular perception, nystagmus is generally caused by lesions in the anterior segment of the eye or the anterior visual pathway, mainly the lesions of the eyeball itself, which blur or disappear the image of objects on the retina, and common corneal opacity, high refractive error, congenital cataract, optic nerve hypoplasia, etc., generally manifest pendulum nystagmus. Patients need to be definitively diagnosed and symptomatic**.

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.
