What is congenital nystagmus?

Congenital nystagmus is a very difficult eye disease to treat and is caused by congenital underdevelopment. This condition is rare, and once you have congenital nystagmus, your eyes will flutter or beat involuntarily. The onset of the disease is young and can be detected in infancy and early childhood.

Patients with congenital nystagmus will also have amblyopia, and the vision of the eye will be greatly affected.

There are many types of eye diseases, and congenital nystagmus is a relatively serious eye disease. The most prominent symptom is the involuntary flutter of the eyeballs, which has a great impact on the patient's image. At the same time, congenital nystagmus can also seriously affect vision, and sometimes the head will also swing unconsciously, which has a certain impact on the daily life of patients.

Symptoms of congenital nystagmus:

1. Unconscious eye tremor: This kind of disease is a congenital development defect, which occurs early, and the patient will involuntarily flutter from a young age. The most obvious feature of nystagmus is that the eyes will swing rhythmically, such as horizontally, vertically, rotationally, and sometimes even mixed.

Sometimes it is a number of frequent shakings, which can be easily detected in appearance, which causes a certain amount of physical and psychological stress on the patient. The flutter of the eye changes in frequency with age, but it does not go away. The patient's nystagmus is constant and slows down only during sleep, due to the inhibitory effect of the upper and lower eyelids, which disappears when the eyelids are closed.

In some patients, the flutter of the eyes is also reduced to some extent when the eyes are relaxed or when they look into the distance.

2. Amblyopia: Generally, patients with congenital eye diseases will be accompanied by amblyopia, and most of them are binocular type, and the gap between the two eyes will not be too big. The patient's visual sensitivity is greatly reduced, and the perception of patterns is weak.

3. Head swing: Many patients with congenital nystagmus will unconsciously swing their heads, which is a very common phenomenon. Because nystagmus is a disease of the central system, the nerves in the patient's eye are involved in the head, causing them to swing together.

Congenital nystagmus means that the disease is congenital, nystagmus is manifested as involuntary rhythmic vibrating of the eyeball, and the appearance is that the eyeball has been shaking, and the direction of swinging back and forth can be horizontal, vertical, or rotational.

Congenital nystagmus is also divided into perceptual according to the cause of the disease, which means that the visual acuity is relatively low, and the most common is caused by congenital cataracts.

There is also a type of impulsivity, also known as perceptual deficit type, this type of nystagmus, the vision is relatively normal, and there is nothing wrong with the eyeball itself, but it is manifested as tremor, that is, the eyes swing back and forth. Some of this kind of oscillation will also show that a swing is faster, which is called the fast phase stage, and a swing is slower, which is called the slow phase stage.

Congenital nystagmus, also known as congenital nystagmus, is a congenital genetic disease.

For this situation, there is no effective method, only with the help of some correction methods to improve the symptoms, such as if there is a refractive error, you need to wear glasses, if the nystagmus is very obvious, you can also wear a prism to eliminate part of the tremor symptoms.

Surgery can improve symptoms, but it does not. Moreover, nystagmus is generally accompanied by other congenital diseases of the eye, such as most farsightedness, astigmatism, congenital eye anomalies, etc.

Every day I think, the state of the eyeball refers to the fact that this disease is a congenital principle, Zhengtai, it is manifested as the performance is not suitable for rhythmic to rotate back and forth, the appearance and feeling is that it has been swaying and swaying and swaying, and it can also be a choice, really, find the reason or, up, intuition, that is, the strength is relatively low, the most common, make, congenital cataract, treasure, and there is a category of impulsiveness, choice, want, intuition, appearance, line, fish, hiking, dynamic vision, comparison, normalThere is nothing wrong with the eyes, the eyeballs themselves, but they are manifested as, Zhengtai, that is, eternity, swinging back and forth this swing, and sometimes it will be, performing, once, swinging, fast, toward, feel, one, think slowly, stage.

What is congenital nystagmus: go to a specialized hospital for consultation. Inspect in detail.

There are many causes of congenital nystagmus, and it is advisable to go to the hospital as soon as possible**.

Congenital nystagmus is detected at birth or within 6 months of birth when a patient has nystagmus, which is an involuntary, regular shaking of the biocular symmetrical and conjugate eyeball. The incidence of congenital nystagmus in people is 1 6500 to 1 1000.

Congenital nystagmus is clinically divided into two types depending on the cause. One is caused by dysfunction of the input mechanism, which is commonly known as congenital leukoendophagia, leukopathy, congenital neurodysplasia, etc., and is also known as self-deficient nystagmus. The other is a disorder of the mechanism of hunger in eye movements, known as idiopathic or motor deficit nystagmus.

Congenital friendly nystagmus is detected at birth or within 6 months of birth when a patient has nystagmus, which is an involuntary, regular shaking of the symmetrical and conjugate eyeballs in both eyes. The incidence of congenital nystagmus in people is 1 6500 to 1 1000. According to the cause of the disease, congenital nystagmus is divided into two types.

One is caused by a disorder of the input mechanism, which is often called congenital cataract, leukopathy, congenital neurodysplasia, etc., and is also known as deficit nystagmus. The other is a disturbance of the delivery mechanism of the ocular motor center, which is called idiopathic or motor deficit nystagmus.

Most congenital nystagmus are caused by genetics. It is manifested as involuntary, rhythmic, and reciprocating eye swings or beats of the eyeball, often accompanied by some organic lesions of the anterior segment, fundus, or optic pathway, such as congenital cataract, glaucoma, or optic nerve dysplasia.

It is divided into surgical and non-surgical, non-surgical** correction methods like prisms, or wearing a hard oxygen-permeable contact lens, or injecting botulinum toxin, or some oral drugs **, such as oral drugs like baclofen or sodium valproate, memantine and other drugs**. Of course, some of these drugs will have some ***, so they are not widely used.

There is this kind of surgery called median type and non-median type surgery**, different types of congenital nystagmus, you can choose different surgical methods.

In clinical medicine, not all nystagmus diseases are congenital nystagmus. Because nystagmus can be divided into four types in clinical medicine: otogenic central, neurotic, tremor and congenital nystagmus. Congenital nystagmus, on the other hand, is caused by an involuntary eye movement within the first six months of life.

Therefore, it can induce neurodysplasia and albinism in patients, and it is necessary to go to the hospital for intervention in time**.

Congenital nystagmus is a type of congenital nystagmus, which is hereditary, and the eyes will beat involuntarily when it occurs, but there are few problems when it turns. Usually, its causes mainly include congenital motor defects, congenital perceptual defects, occult nystagmus, etc. Due to the complexity of this disease, patients should pay special attention.

In general, the tremor of the globe can be divided into two types: congenital and acquired, among which the causes of congenital nystagmus are complex, and the tremor will vary in different patients. Most nystagmus may be caused by essential tremor, so congenital nystagmus is hereditary. In addition, some other factors, such as physiological factors, may also cause the disease, in which case the hereditary chance of the patient will be smaller.

Below, we will introduce several causes of this disease.

1. Congenital motor defects.

This condition is usually associated with primary abnormalities in eye movement control, and most cases of tremor disorders are recessive, although some patients are chromosomally dominant.

2. Congenital perceptual defects.

Congenital sensory defects are usually caused by eye diseases, such as congenital cataracts, glaucoma, Peter's anoma, etc. At the same time, if the patient's retina is damaged or damaged, the optic nerve is not well developed, such as defects, atrophy, etc., it may also cause nystagmus. In addition, some visual cortex damage caused by abnormalities in the nervous system can also cause congenital nystagmus.

3. Occult nystagmus.

When a patient undergoes congenital esotropia correction surgery, the patient's eyes may interfere with each other, resulting in vision loss and even nystagmus. This condition is mainly caused by improper post-operative care, and patients can wear polarizers and have regular vision check-ups after surgery, so that the condition can be avoided to a certain extent.

Nystagmus 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. Mainly caused by genetic mutations, nystagmus is not an independent disease, but a clinical manifestation of some diseases, nystagmus needs to be carried out for **, and reproductive intervention can be carried out through genetic testing to prevent the occurrence of nystagmus.

It is usually due to the recent lack of sleep, too much pressure, plus excessive eye use, visual fatigue or poor vision, symptoms, relief methods, adjust the mentality, pay attention to rest and eye use, control the use of mobile phones, computers, TVs and other fine eyes, if there is refractive error, be sure to wear glasses, plus some moisturizing eye drops, such as polyvinyl alcohol eye drops, do eye massage, hot compress, if the symptoms do not improve, go to the hospital ophthalmology department for examination. Ophthalmic nystagmus: nystagmus caused by low vision that makes the fixation reflex difficult.

2. Vestibular nystagmus: nystagmus due to inner ear and vestibular lesions.

3. Central nystagmus: nystagmus caused by brain nerve pathway lesions caused by inflammation, tumor, degeneration, trauma, and vascular diseases.

4. Congenital idiopathic nystagmus: there are no obvious organic lesions, and the loss of vision is mostly caused by physical image tremor, and the tremor can be reduced in a certain field of vision, which is called resting eye position in medicine.

Principles of nystagm**.

1) Correction of refractive error, if accompanied by amblyopia, it should be at the same time**.

Active**Primary disease.

3) Optical correction: Correct the head position by wearing a suitable prism to improve vision. 4) Biofeedback**: Auditory feedback technology is used to make nystagmus movements sound, and the nystagmus is controlled by the patient's self-training.

5) Surgery**: Although surgery does not cause nystagmus, surgery can move the resting eye to the front and reduce or suppress the frequency of nystagmus.

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.

**。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.

Main**. Oculogenic nystagmus.

Nystagmus is caused by visual impairment in the center of the macula, which makes the fixation reflex difficult.

Vestibular nystagmus.

Nystagmus due to lesions in the vestibular nucleus or its pathways connecting with the cerebellum or brainstem.

Central nystagmus.

It is more common in bulbar lesions, pontine lesions, midbrain lesions and cerebellar lesions.

Congenital idiopathic nystagmus.

A congenital condition, currently unknown, pending further study.

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.

Epidemiology. The prevalence of congenital nystagmus in foreign countries is still lacking in clear epidemiological statistics in China.

Hello, the symptoms of congenital nystagmus are as follows:

1. Involuntary persistent and regular nystagmus. Congenital nystagmus begins very early, and patients experience involuntary nystagmus. Congenital nystagmus usually occurs in both eyes at the same time, and the duration of the onset varies, and the patient's eyes will beat or sway involuntarily, and some patients have a sense of vision.

2. Amblyopia. Patients with congenital nystagmus develop amblyopia in both eyes, and if there are no complications such as strabismus or refractive error, the degree of amblyopia in both eyes is usually about the same. Amblyopia is prevalent in patients with congenital nystagmus, mostly severe, with decreased visual function and a marked decrease in sensitivity to graphics and movement, but color vision is normal.

3. Compensate the head. Compensatory cephalic position refers to the left and right deflection of the patient's face, and a small number of patients with congenital nystagmus have the jaw raised or adducted.

4. Compensatory frequent blinking. Some patients with congenital nystagmus will blink frequently, and the more the patient pays attention to the target, the higher the frequency of blinking, which is related to mental stress. There is no impairment in the movement of the patient's eyes, and corrected visual acuity is usually above.

In addition to the above symptoms, there is also abnormal projection, also known as hyperdactyly, in which a person with paralytic strabismus looks at an object with the affected eye and tries to touch the object with his hand, but the hand always fails to touch the object accurately and tilts to one side. Therefore, you should go to the hospital for examination in time after you find it**.
