The movement of the eyes is controlled by the brain, and if the brain is too tired, the eyeballs are prone to tremors, and there are many causes of nystagmus. In some cases, the cause is unknown. But in some cases, nystagmus may be associated with other eye diseases.
Like heredity, nystagmus is heritable, cataracts, strabismus and severe refractive errors etc. Nystagmus can cause decreased vision, turbulent vision, nausea and vomiting, etc.
-
This situation should be a long time of overuse of the eyes, caused by excessive eye pressure, this tremor feeling, this is very unhealthy, be sure to go to the hospital in time for examination, if you do not pay attention, there may be eye mask peeling or other more serious problems.
-
Tremors are caused by excessive strain of your eyeballs and affect the health of your eyes. Usually reduce the radiation of electronic products to the eyes, and look into the distance for a while after working for a while.

The first and the mechanism of nystagmus are complex and uncertain, which may be caused by congenital genetic factors, or may be the clinical manifestations of other ocular and otogenic diseases. Genetic factors and environmental factors are both involved in the pathogenesis.
First, the main **.
1. Oculogenic nystagmus: refers to nystagmus caused by the impaired optic hall in the central hall of the macula, which makes the fixation reflex difficult.
2. Vestibular nystagmus: nystagmus caused by lesions in the vestibular nucleus or its communication pathways with the cerebellum or brainstem.
3. Central nystagmus: more common in bulbar lesions, pontine lesions, midbrain lesions and cerebellar lesions.
4. Congenital essential nystagmus: a congenital disease, which is currently unknown and needs further research.
5. Others: may be related to heredity, with X-linked recessive inheritance being the most common, manifested as parents with disease, and children with high risk of disease. Some eye shocks can be caused by drugs or toxic substances.
2. Predisposing factors.
1. Usually blinking, resulting in eye muscle nerve fatigue and paralysis, which can congenitally induce nystagmus.
2. Maintaining an action for a long time can lead to fatigue and paralysis of eye muscles and nerves, which can congenitally induce nystagmus.
3. Congenital amblyopia, the eye itself is not perfectly developed, and it is very easy to have congenital nystagmus.

Nystagmus is an involuntary, rhythmic, and reciprocating eye swing or beat. Nystagmus is usually classified into horizontal nystagmus, vertical nystagmus, rotational nystagmus, and mixed nystagmus depending on the direction of their direction. In nature, it is divided into physiological nystagmus and pathological nystagmus.
Nystagmus is usually just a symptom of a disease.
Common causes. 1.Oculogenic nystagmus: such as congenital amblyopia, severe refractive error, congenital cataract, high myopia, albinism, extraocular muscle paralysis, etc.
2.Vestibular nystagmus: common in Meniere's syndrome, otitis media, labyrinthitis, etc.
3.Central nystagmus: seen in syringomyelia, multiple sclerosis, cerebrovascular disease, encephalitis, cerebellar tumors, etc.
4.Toxic nystagmus: drug poisoning, such as opioids, barbiturates, ethanol, lead poisoning, etc.
Nystagmus is an involuntary, rhythmic characteristic eye movement that is generally caused by an abnormality in eye movement due to certain vision-related nerves or vestibular lesions.
Congenital motor nystagmus is mainly due to defects in the control mechanism of the nerve center or the same motor pathway, but there are no abnormal changes in the eye, which is mostly genetic. In the case of sensory deficit nystagmus, it is generally a defect in the visual afferent path secondary to blurred vision in the macula, causing feedback disorders, resulting in impaired story reflex development, loss of function of the micromotor system in the fovea, and nystagmus.
Recessive nystagmus is a horizontal impulsive nystagmus in which both eyes are open without nystagmus, and nystagmus occurs when one eye is covered, and the fast phase is directed at the uncovered eye, that is, the fixation eye, or it can be manifested as overt nystagmus with additional recessive nystagmus, and the amplitude of nystagmus increases and vision decreases after covering either eye.
-
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. This type of tremor has chronic and fast phases, with chronic being physiological and fast being corrective movements. The fast phase direction is the direction of nystagmus, and the fast phase is related to **.
-
Nystagmus is a symptom of a reciprocating movement of the eyeballs with a marked difference in velocity, and when the eyes slowly turn in a plus direction to a certain extent, they suddenly return in a rapid motion. There are many people who suffer from this disease, and it is good to be timely and effective, otherwise the harm caused by the serious condition is very great.
1. The harm of nystagmus is very great, as long as the disease is diseased, it is particularly difficult, if it is not good, the disease will lead to amblyopia, which will make the patient see things clearly.
2. Nystagmus will make the patient have strabismus, because the eyes see things clearly, so the eyes will squint because they can't see things clearly when they use it for a long time, so that it is an obvious disease of strabismus for a long time.
3. Patients with nystagmus cannot see things clearly, and they will shake after looking at things for a long time, and there will often be deviations and squints, so that if they do not change for a long time, they will become habitually crooked.
4. Many patients will have eye pain because of eye discomfort and eye pain for too long, and the patient's head may also be painful because of eye pain.
5. If the disease of nystagmus is not treated in time, there will be a series of symptoms, which will have a great impact on the patient's body, life and work, and even endanger life and lead to family breakdown.

Nystagmus is an involuntary, rhythmic, back-and-forth swinging eye movement, which is a common disease, which can be acute or chronic, often caused by diseases of the visual system, extraocular muscles, inner ear labyrinth and central nervous system, which can lead to amblyopia, torticollis, blindness, etc. Nystagmus is not an independent disease, but a clinical manifestation of certain diseases, so it should be targeted. Nystagmus does not heal on its own, and there is currently no way to completely.
What is nystagmus.
Oculogenic nystagmus refers to nystagmus that occurs when the central macular vision disturbs and makes the fixation reflex difficult.
Vestibular nystagmus Nystagmus caused by lesions in the vestibular nucleus or its pathways connecting to the cerebellum or brainstem.
Central nystagmus is more common in bulbar lesions, pontine lesions, midbrain lesions, and cerebellar lesions.
Congenital essential nystagmus is a congenital disorder that is currently unknown and needs further research.
Others may be related to genetics, 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.
-
Nystagmus is mostly caused by developmental abnormalities and can occur after nerve damage.
1.Nystagmus is an involuntary, regular oscillation of the eyeball,** which is not yet well understood, and is mostly seen due to congenital factors, due to abnormal development of the neural structure of the cerebral cortex. Most of these patients have no self-conscious symptoms, and there are no uncomfortable symptoms such as dizziness, headache, and blurred vision.
If the abnormal sign does not interfere with the person's daily life, it can be left untreated. If there are other complications, the skull should be examined in detail for the primary disease and considered symptomatic**.
2.Nystagmus can also be seen in patients with diseases that affect vision, such as macular degeneration, congenital glaucoma, and retinitis pigmentosa, because the patient has poor vision and is unable to fix vision, so nystagmus is caused. Some neurological disorders, such as intracranial hemorrhage, can also cause nystagmus.
-
Nystagmus can be divided into congenital nystagmus and acquired nystagmus. Most patients have congenital nystagmus, and in congenital nystagmus, they are divided into perceptual nystagmus and motor deficit nystagmus.
Perceptual nystagmus, often accompanied by other eye disorders, such as physical deprivation, congenital glaucoma, congenital cataracts, and even fundus diseases with congenital optic dysplasia, can affect the child's visual function.
There is also a type of kinesthetic deficit nystagmus, which can also be called congenital infantile nystagmus syndrome, which is usually accompanied by fast and slow phases of tremor.
-
It is caused by lack of sleep or stress and listlessness.
-
Nystagmus is not a simple disease, but a condition that causes low vision due to various reasons, resulting in the inability of the eyeballs to see.
This is because when the eyeball looks at objects, it forms a vision through the macula. If the patient has nystagmus, the eyeballs will continue to flutter and they will not be able to see, which will cause low vision.
Therefore, when the patient has low vision, he must go to the hospital for examination and ** in time.
-
Nystagmus causes may be related to genetics, difficulty forming fixation reflexes, impaired vestibular function, impaired brain function, and the specific cause is related to the type of nystagmus. Nystagmus can be divided into congenital nystagmus, oculogenic nystagmus, vestibular nystagmus and central nystagmus.
3.Vestibular nystagmus: vestibular nystagmus fibrillation caused by impairment of vestibular function due to ear disorders such as Meniere's syndrome.
4.Central nystagmus: impaired cranial function due to brain tumors, trauma, inflammation, vascular lesions, etc., may lead to central nystagmus.
In addition, nystagmus may be induced or aggravated by drugs or poisons, or when they are often in contact with moving objects.
It is recommended that patients with nystagmus seek medical attention in time, be clear**, and follow the doctor's advice**.
-
The causes of nystagmus are mainly caused by diseases of the visual system, extraocular muscles, and central nervous system. Tomb
Nystagmus may occur due to changes in the retina or refractive mediator. 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 the appearance of nystagmus. Nystagmus can also occur due to central lesions, which cause horizontal, rotational, or vertical tremors, which are characteristic of brainstem disorders.
The occurrence of nystagmus is also related to genetic factors, this form of inheritance is mainly autosomal dominant or recessive hail grip 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 head vibration or point movement, but the patient has no conscious symptoms.

Many times, we are not sure that we can do everything well, we even have a subconscious fear of failure and setbacks, and at our age, we really don't know what we like, what we want to do, and we don't know how big the world really is. We groped step by step, growing little by little, shouting "I can do it, I will definitely succeed", in fact, because of the shallow experience and little knowledge, it is inevitable that there are a lot of uncertainties about the world in our hearts. I'm like this sometimes, I suddenly lose my heart, I don't have the strength to do anything, that's because I'm sad in my heart, as for what things are sad, isn't it something that can make me unhappy, between husband and wife; But it's good to mourn and mourn, why? >>>More
