What s the deal with nystagmus?

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 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.

Congenital nystagmus, partly due to a family genetic disease, and partly due to a history of infection during pregnancy, such as viral infection, can cause congenital nystagmus.

For genetic diseases, there are often organic lesions of the anterior segment, fundus or optic pathway, such as congenital cataract, congenital glaucoma, congenital aniridia, familial amaurosis, and congenital optic nerve dysplasia, which can lead to congenital nystagmus. There is also a part of the eye that does not have organic lesions, but there are some lesions in the brain, that is, the nerve center, so it can also lead to abnormal motor function of the eye and congenital nystagmus.

1.Ocular nystagmus. Refers to the central macular visual impairment, which is nystagmus caused by difficulty forming the fixation reflex

1) Physiological fixation nystagmus includes oblique nystagmus, visuodynamic nystagmus and recessive nystagmus2) Pathological fixation nystagmus includes blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc

Nystagmus is a congenital genetic disorder that is an ocular symptom caused by a congenital developmental abnormality that manifests as involuntary, rhythmic eye movements.

Nystagmus is an involuntary, rhythmic, oscillating eye movement. Directions can be divided into horizontal, vertical, and rotation types. Horizontal is common.

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 a stand-alone condition.

Nystagmus, more support, due to some eye diseases or central nervous system diseases, the basic ** is congenital eye malformation, ocular neuromuscular dysplasia cataract. Damage to the macula in panchromatopsis may also be due to acute vestibular impairment in some otitis media.

There are many causes of nystagmus, which can be broadly divided into two categories: congenital and acquired. Nystagmus is caused by congenital factors, usually due to genetic or developmental abnormalities. Acquired nystagmus may be refractive error or brain disease.

When you're overwhelmed by pressure, remember that it's because of the pressure that carbon turns into a sparkling diamond.

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.

(1) Physiological fixation nystagmus: it includes oblique nystagmus, visuodynamic nystagmus and recessive nystagmus2) Pathological fixation nystagmus:

It includes blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc 2.Vestibular nystagmus.

Nystagmus caused by lesions of the vestibular nucleus or its pathways with the cerebellum or brainstem

Nystagmus is an involuntary, rhythmic, back-and-forth eye movement. There are two main clinical manifestations of nystagmus: 1. Throbbing type, in which the eyeball moves back and forth at different speeds.

When the eyeball slowly turns in the other direction, reaching a certain point, the eyeball will suddenly bounce back. This type of tremor is characterized by a chronic and rapid phase, with chronic being the ,.. menstrual phase

If you always have nystagmus, it must be very uncomfortable, and if you have nystagmus, I think you should still have to go to **, that is the best.

Nystagmus is not an independent condition, and after the primary has not been effective, there are options to improve clinical symptoms.

nystagmus (nystagmus; ny) is an involuntary, rhythmic, back-and-forth eye movement. The direction is divided into horizontal, vertical, and rotational type, with the horizontal type being the most common, usually the fast-phase direction indicating the direction of nystagmus, and the fast-phase being the compensatory recovery of fixation movement. Referred to as nystagmus.

It is often caused by diseases of the visual system, extraocular muscles, labyrinth of the inner ear, and the central nervous system. Nystagmus is not a stand-alone disease, but a clinical manifestation of certain diseases, so it should be targeted.

The causes of nystagmus are complex. There are physiological and pathological ones, and the current mechanism of pathogenesis is not fully understood, and it is generally believed to be related to the impairment of fixation and orientation function. Ophthalmologic tremor is called ophthalmic tremor, such as nystagmus due to lack of vision in both eyes or in the form of fixed vision dysfunction due to low vision, which is more common in people with vision loss in infancy and early childhood.

Or if you are in a dark environment for a long time, the cones that sense light are inhibited, and the eyes will lose their ability to fix their vision and tremble. Nystagmus can also be caused by paralysis of the eye muscles or dysfunction of the vestibular system.

It is better to go to a hospital with professional medical equipment as soon as possible to inquire.

What's going on with nystagmus, you have to ask the doctor in the hospital

The eye is the window of the soul, the eye is very important to the human body, but a lot of hot eyes will have problems now, the most common is nystagmus, there are many people who suffer from nystagmus in life, and it is necessary to ** when nystagmus occurs, now let's understand the causes of nystagmus.

Lesions in the retina or refractive media may cause 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.

There are also nystagmus patients who are 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. Lesions in the center can also cause 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.

The occurrence of nystagmus is also 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 head vibration or pointing, but the patient has no conscious symptoms.

Through the above content, I believe that everyone has a certain understanding of nystagmus, so once the patient understands the onset, he should go to the hospital in time, so that he can seize the best opportunity, and the disease can stay away from us as soon as possible, and then it will not affect the normal life and work of the patient.

Nystagmus is mostly caused by some ocular origin. Otogenic. Central neuronal or other lesions, resulting in abnormal eye movements.

Oculogenic nystagmus is common** with congenital eye malformations. Neuromuscular dysplasia of the eye. Cataract. Total color blindness. Yellow shift damage, etc.

Otogenic addiction, commonly seen in Meniere's syndrome. Tympanitis. Labyrinthitis. Acute vestibular impairment, etc.

Central nystagmus, common in encephalitis. Brain tumors. Cerebrovascular disease. Traumatic brain injury. Brain**. Ataxia. Stroke or multiple sclerosis, etc.

Others may be related to genetics. X-linked recessive inheritance is the most common. Presents as a parent with a disease. Children are at high risk.

Some are caused by inflammation, accents, medications, or toxic substances.

There are special occupations such as coal miners. Train dispatcher. Occupational nystagmus is predisposed.

Some patients with thyroid dysfunction. May be associated with neurological symptoms such as nystagmus.

Nystagmus, often referred to simply as nystagmus. Nystagmus is a rhythmic movement of the eye that is not controlled by the person's consciousness. Among them, vestibular nystagmus is caused by the alternating slow and fast movement of the eyeball, and nystagmus can be divided into two categories: sensory deficit nystagmus and motor deficit nystagmus.

**There are still many of them, and ocular nystagmus refers to nystagmus that occurs when a central vision disturbance makes the fixation reflex difficult. (1) Physiological fixation nystagmus: oblique nystagmus, visuodynamic nystagmus and recessive nystagmus.

2) Pathological fixation nystagmus: blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc. There are also vestibular nystagmus, central nystagmus, congenital essential nystagmus.

Congenital nystagmus is a clinical manifestation, it is not an independent disease, it is very complex and harmful.

Nystagmus is congenital, a developmental problem, and some are related to genetics. There is no special ** measure for this, the light one has no effect, and the heavier one can be accompanied by small eyeballs, and the vision is significantly reduced, which can be corrected by refraction and wearing appropriate glasses.

After nystagmus, there is often decreased vision or severe visual impairment in the eye. In addition, there is left and right flutter or up-and-down flutter of the eyeball, which can be divided into horizontal nystagmus and vertical nystagmus, and nystagmus generally does not exist in isolation. It mainly has some manifestations of syndromes, after the occurrence of nystagmus, it should be actively examined, carefully exclude systemic lesions, cranial lesions, some lesions of the eye, mainly pay attention to the cause of tremor and the direction of tremor visual acuity.

If there is visual impairment, it should be positive**Visual conditions, horizontal tremor or vertical tremor, the resting position of the tremor should be chosen, and surgery can be considered**. Usually you should pay attention to rest, reduce close-up operations, avoid visual fatigue, eat lightly, and pay attention to your eyesight.

In everyday life, some people may suddenly feel a nystagmus, but they don't take it to heart. In fact, nystagmus is a very serious matter that should be taken seriously. Nystagmus is an eye movement that is often involuntary, rhythmic, and oscillating back and forth that people can feel but easily ignore.

There are several directions of movement for nystagmus, such as horizontal, rotational, vertical, etc., and the most common is horizontal. Why nystagmus occurs can be summarized into two reasons:

Reason 1: Some scholars believe that congenital nystagmus is the failure of the subbranch system of slow motion control of the eyeball, which acts under abnormal conditions of high gain, and this special abnormality may be manifested in the feedback effect of the signal about the position and speed of the eye transmitted by the proprioceptor of the extraocular muscle, and the result of the unstable feedback causes the position of the eye to be unstable and the eye deviates from the positive position, which constitutes the slow phase of tremor, and the fast sweeping motion makes this slow phase interrupted and returns to the fixation position, which constitutes the fast phase of tremor.

Reason 2: Other scholars believe that it is a defect in the subcortical visual and dynamic system, which causes the fixation to be unstable and the eye deviates from the fixation position, while correcting the eye movement causes the eye to return to the fixation position.

Nystagmus is mostly caused by some ocular origin. Otogenic. Central neuronal or other lesions, resulting in abnormal eye movements.
