How to detect amblyopia in children early? How amblyopia is formed in children

What is the difference between amblyopia and myopia.

This must go to a regular eye hospital to see, the child can grow up early without glasses, there are examples around, hope to be healthy.

If there is no obvious organic lesion of the eyeball, but the corrected visual acuity of one or both eyes still does not reach 1 0, it is called amblyopia. At present, the standard for amblyopia in China is corrected visual acuity of 0 8 or poor visual acuity of 2 lines in both eyes. Amblyopia is an eye disease that seriously harms children's visual function.

If children's myopia is not effectively controlled, it is easy to develop into high myopia, resulting in a series of pathological changes, and will become incurable blindness after entering middle and old age. According to statistics, more than 30% of senile blindness is caused by severe complications such as glaucoma and cataract caused by sclera stretching after high myopia. Strabismus amblyopia in children may also develop into low vision or blindness if it is not early and immediate**.

Low vision in one or both eyes, often below 0 3, and cannot be corrected with lenses, and fundus examination is normal. The recognition of a single optoscope is much higher than that of a single optoscope arranged in rows of the same size (2 rows and 3 rows), which is called crowding or difficulty separating. Such patients are often accompanied by features such as ocular deviation or nystagmus, and abnormal fixation properties.

Symptomatic manifestations - 2

1) First of all, parents should understand that the normal vision of children of different ages is different, and the visual development of normal children is gradually improved with the growth of children. The normal visual acuity of children at different ages in China is: 2 years old to 2 years old; 3 years old; 4 years old; 5 years of age and older or above.

In general, children's visual development tends to stabilize between the ages of 6 and 8 years. If you don't understand this, it's easy to mistake children with normal vision for amblyopia.

2) Guide children to wear glasses when looking at close objects, especially when drawing and writing, which can often achieve the effect of getting things done.

3) Children should be examined at an early age, and once refractive errors such as myopia, farsightedness, and astigmatism are found, they should wear appropriate prescription glasses in time under the guidance of professionals to avoid the development of amblyopia.

4) Be patient and persuade your child to insist on wearing glasses. In addition to bathing and sleeping, it is important to wear glasses, especially when covering healthy eyes, and the temples should be connected with a chain to prevent the glasses from breaking.

5) After the child has amblyopia, he should have a correct understanding of the eye disease of amblyopia, and fully understand that the process of amblyopia is slow, and the vision is gradually improved.

Symptoms of amblyopia are:

1. Fear of light: Amblyopia children are usually afraid of light and irritable when they see light.

2. Nystagmus: abnormal beating of the eyes, resulting in poor vision.

3. Deviation of the eye: Occasional or frequent inward or outward deflection of a single eye, which is a precursor to amblyopia.

4. Poor eye posture: Every time you need to use your eyes, your head will be deflected and tilted, or your chin will be lowered or raised.

5. Poor eye-hand coordination: easy to collide or fall.

6. Dyslexia: When reading, you use your eyes too closely, often see the wrong line, or look at the opposite or inverted or ghosted words when you read and write.

7. Abnormal eye appearance: such as drooping eyelids, white spots on the black eyeballs, and different eye sizes.

1. The size or shape of the pupils varies.

Once the above symptoms of amblyopia appear, please go to a professional eye hospital for examination**. The sooner amblyopia is better, and the more timely it is, the more likely it is that visual function will recover.

It may be refractive error, anisometropia, strabismus and congenital diseases, or it may be that you can't open your eyes when you are born, so you cover your eyes and cause amblyopia.

Generally, it is due to the influence of the child's genes, or the physical aspects of pregnancy, which cause the child's vision problems.

It is generally due to genetic reasons, and some parents have amblyopia, so children also have amblyopia.

1.Vision and refractive abnormalities.

The boundary between amblyopia and normal vision is not very clear, and some patients complain of decreased visual acuity, but on objective examination, visual acuity remains or. This may be when the patient feels a decrease in vision compared to their previous vision. In addition, there may be some disturbance in the optic cells in the fossa or in the conduction system behind it, with a very small central scotoma, and there is a perceived visual disturbance, which cannot be detected objectively.

If there are no organic changes in the amblyopia eye, and its visual acuity is above or below, it is often accompanied by fixed vision abnormalities.

The relationship between amblyopia and refractive abnormalities is that hyperopia accounts for a large proportion of eyes, and myopia has more mild amblyopia, so amblyopia is closely related to those with high degree of farsightedness.

Esotropia is more common than exotropia in severe amblyopia in strabismic amblyopia, possibly because esotropia develops earlier than exotropia.

2.Dyslexia.

Or crowding. When visual acuity is examined with the same optoscope, illumination, and distance, the measured values are different depending on the interval between the optoscopes. Dyslexia is a feature of amblyopia.

Dyslexia is the ability of the amblyopic eye to recognize individual optograms better than to recognize aggregate or dense optoscopes. That is, the resolution of single-page fonts (such as E characters) on the eye chart is stronger than that of words in rows.

3.Amblyopia occurs only in young children.

Amblyopia develops gradually between birth and 9 years of age. During this development, amblyopia can be caused by strabismus or loss of form sensation. Amblyopia does not occur after the age of 9, even if there are any of the above reasons.

4.Amblyopia occurs only in patients with monocular vision.

Amblyopia does not occur if the two eyes are used alternately.

5.Abnormal fixation.

Patients with deep amblyopia often use the omentum next to the macula instead of the macula for fixation due to the poor ability of macular vision fixation. Eccentric fixation refers to the fixation of the central fossa, and there are many theories of its formation, but its manifestations include parafoveal fixation, peripheral fixation, paramacular fixation, and migratory fixation.

Amblyopia may be an eye disease that is relatively unfamiliar to parents, it is an eye disease in which there is no obvious organic lesion of the eyeball, and the best corrected visual acuity of one or both eyes is lower than the corresponding age. In layman's terms, it means that after wearing glasses, the best vision is still not up to the level of vision of peers.

Amblyopia in children 1: Abnormal behavior observation method.

For example, seeing if things are close together, not being able to distinguish the correct route when walking normally, such as easy to fall and fall, sometimes holding things inaccurately, not being sensitive to light things, etc., are all due to the competition between clear and blurred objects due to the unequal visual input of the two eyes.

Amblyopia 2: Vision test.

Ophthalmologists remind that after the child is 3 years old, a complete visual acuity and eye examination should be carried out, screening methods: visual acuity - eye position - stereoscopic vision - optometry. If vision is not reached by the age of 3 to 5 years and is still below by the age of 6, the possibility of amblyopia is considered.

Children with amblyopia 3: monocular occlusion experimental method.

Covering one eye and fixing the object with one eye, if you tear the covering, it means that the uncovered eye may have poor vision, which is suitable for early childhood.

Amblyopia** is age-related.

Amblyopia is a common eye disease during eye development, which is very harmful to the eyes. The age of 3 to 7 years is a critical period for amblyopia**, and the effect is minimal beyond the age of 12**. Because the child is too young to express himself, if the parent is careless, missing the opportunity often causes regret.

The small ones can't see clearly, the far ones and the near ones include, and the smaller they are, the more they can't see clearly.

Symptoms of amblyopia in children: reading or looking too close to see, squinting to see, tilting the head to see, children with anisomediopter amblyopia are prone to this manifestation. The child cannot see clearly, so a series of these life manifestations may be one of the manifestations of amblyopia.

The disease is a disease of abnormal visual function, and there will be no organic lesions in eye examination, which will seriously affect the development of visual function and even blindness. The best-corrected visual acuity of one or both eyes is lower than the visual acuity of the appropriate age; or if the visual acuity of both eyes differs by two lines or more, the lower visual acuity is amblyopia. In addition to vision loss, which is the main symptom of the disease, amblyopia can also affect all aspects of visual function, such as light, color, kinesthetic, and contrast sensations.

Early age is critical, and the younger the age, the higher the rate, and the better the prognosis.

There are five symptoms of amblyopia:

Likes to tilt your head. Use only one eye to see things and the other eye to not be able to pay attention to what is being seen.

Poor photophobia-hand coordination.

Abnormal eye appearance.

1、.Low vision in the amblyopia eye.

2. It is difficult to see far and near.

3. It is more difficult to see things when the light is bad.

4. Slow to distinguish the size, light and shade, and shape of objects.

5. When amblyopia children look at things, from near to far, the range of adjustment ability changes6. When amblyopia children walk, they show that they have one shallow foot and one foot, and they are easy to fall 7. Amblyopia children lose stereoscopic vision. Writing often overlaps, is not neat, and does not form lines.

Amblyopia in children may have the following manifestations:

1. Strabismus, which is a precursor to amblyopia, which is a precursor to amblyopia;

2. Fear of light, children with amblyopia are usually more afraid of light, and they are relatively irritable when they see light;

3. Like to tilt your head and read with a biased face;

4. Poor eye-hand coordination, easy to collide or fall;

5. If you look at things closely, you will usually find that your child will walk in front of you while watching TV, and you will find that the child who goes to school will read or write in the opposite or upside down, and the teacher will reflect that he cannot cooperate well with the teacher's instructions at school. If your child has any of the above symptoms, you must take your child to the hospital for a check-up.

How to have amblyopia in children**

1.Cover**.

This method can be divided into full and partial masking. The aim is to cover the healthy heel and force the amblyopia eye to fixate and perform delicate work. The method of covering should be selected according to the age and visual acuity of the child.

After the first stage**, if the child's visual acuity does not improve, and the visual acuity of the two eyes is 2 lines apart or does not reach the lower limit of the mean visual acuity of children of the same age, the current stage ** is continued.

2.Correction of amblyopia**.

The first step is to wear appropriate corrective glasses to correct refractive errors. Early** congenital, traumatic cataract and complete ptosis.

3.Repression**.

Suppress the function of healthy eyes with under-corrective lenses and daily atropine, and wear normal corrective lenses for amblyopia. Depression** has depression to see far, depression to see near, and complete depression, which is suitable for children with moderate amblyopia, slightly older and unwilling to cover**.

What are the dangers of amblyopia in children?

1.Affects the child's image.

If amblyopia is not **, the child's vision will not be able to improve. If it is strabismus amblyopia, surgical correction may be necessary, because failure to correct it will affect the child's external appearance.

2.Affect the psychological development of children.

Amblyopia can also affect children's psychological development, and children may have a shadow in their hearts or have low self-esteem. For example, when he is with children, he always feels that he is special and has defects, especially strabismic amblyopia. Therefore, parents must pay attention to the problem of amblyopia in children.

3.Affect the healthy growth of children.

In addition, it will also affect the healthy growth of children, and may also affect children's intellectual development.
