What is the cause of amblyopia and what is amblyopia

You can go to Hefei Purui to see, This summer, Professor Yue Yiying, a well-known pediatric strabismus and amblyopia expert in the country, and Professor Yue Yiying of Tianjin Eye Hospital, will jointly consult with Xu Xinhua (former doctor of Hefei First People's Hospital) to diagnose the problem of strabismus and amblyopia in children, conduct a comprehensive examination for children, and solve parents' worries.

Congenital reasons, premature birth is also a reason, Beijing's Guangcai Tomorrow Children's Eye Hospital is a hospital specializing in amblyopia strabismus, if the child is amblyopia, the older the effect will be.

Condition re-analysis: Hello, amblyopia is due to abnormal visual experience within the visual development period

For example, monocular strabismus, refraction.

Guidance on causes such as i.osome, high refractive error DAO, and form deprivation: the best corrected visual acuity decreased in one or both eyes, and there were no organic changes in ocular examination. The age factor of amblyopia is very important, and the younger the age, the better the curative effect.

Amblyopia refers to the fact that during the period of visual development, the best corrected visual acuity is lower than the lower limit of normal for the same age or more than 2 lines different from binocular visual acuity due to abnormal visual experience such as monocular strabismus, anisometropia, uncorrected refractive error, and morphological plate deprivation.

Visual development: This process begins at birth, with a critical period before the age of 3 and a sensitive period before the age of 9 and lasts until about the age of 12.

There are**: strabismus, refractive error, form deprivation, etc.

Best-corrected visual acuity, not uncorrected visual acuity, visual acuity is judged by age (not less than 3 to 5 years old, not less than 6 to 7 years old, and 7 years old or older. ）

Harm of amblyopia: It affects the development of vision, causes strabismus, and affects the higher visual function of both eyes.

There are many causes of amblyopia, which can be due to.

du strabismus. Eye position.

Diplopia can occur with bias, and the brain actively inhibits the nerve impulse from strabismus, resulting in amblyopia over time. It can also be caused by large anisometropia between the two eyes, long-term obstruction of the vision of the affected eye for some reason, inhibition of visual function development, high refractive error in one or both eyes, congenital amblyopia and other reasons. The main manifestation of the child is vision loss, and the lack of vision after refractive correction is amblyopia.

Although amblyopia is a common disease and many children suffer from it, there are still many people who are not.

The following is an introduction to several common causes of amblyopia, hoping that you can find the cause of your child's illness and correct your child's eye habits through the following explanation.

Amblyopia, to put it bluntly, is that the eyes are fine, but the vision is not normal, for example, just like a computer, the hardware equipment is intact, but it can't work normally, so what is the problem? There must be something wrong with the software. And this software is equivalent to our children's visual center system.

The latest foreign research shows that the deep cause of amblyopia lies in the imbalance of the eyes. For children with amblyopia, the healthy eye will inhibit the expression ability of the amblyopic eye, and the brain will actively turn off the visual function of the amblyopia eye in order to obtain accurate information.

Amblyopia mostly refers to the absence of organic lesions inside and outside the eyeball but the corrected vision does not reach the normal range, and there are many reasons for amblyopia, such as low weight caused by premature birth, excessive use of eyes, genetics, etc., it is recommended that you do further examinations, and then take targeted **, amblyopia should be timely**, otherwise it will affect the child's later vision.

Amblyopia is caused by complex and a variety of diseases can be caused, generally caused by refractive error, anisometropia, strabismus, etc., the best way to wear appropriate glasses to correct and cover the eyes of amblyopia, all of which are indispensable, and most of them will be cured through **.

Abnormal visual experience during visual development: monocular strabismus, anisometropia, and decreased best-corrected visual acuity in one or both eyes due to high refractive error, with no organic parenchymal lesions in the eye.

The incidence of amblyopia in China is 2%-4%, and amblyopia is generally divided into: strabismus amblyopia, refractive error amblyopia, and form deprivation amblyopia. Amblyopia patients can cause blurred vision, photophobia, lack of stereoscopic vision, easy falling, difficulty concentrating, etc.

Amblyopia has a lot of congenital factors, or problems with refractive development can also be caused, generally early detection of early **, I love in Wuhan occasionally meet a lot of such children, generally 3 6 years old ** rate is very large, after 12 years old ** effect is not obvious.

1. Refractive error: medium to high hyperopia, high myopia, medium to high astigmatism.

2. Ansometropia: the power of the two eyes is quite different.

3. Deprivation of form sense: congenital cataract, ptosis.

4. Strabismus: mostly seen in non-alternating nature.

Amblyopia is called amblyopia if there is no obvious organic lesion in the eyeball and the corrected visual acuity of one or both eyes still does not reach the best corrected visual acuity. Amblyopia is an eye disease that seriously endangers children's visual function, and can cause amblyopia to worsen if not timely**.

What should I do if my child's astigmatism can be recovered, and it is normal now.

Disease definition. Amblyopia lazy eye is the absence of organic lesions on eye examination when the best-corrected visual acuity of one or both eyes is lower than that of the appropriate age, which is caused by abnormal visual experience during the period of visual development. These abnormal visual experiences include monocular strabismus and high refractive error.

anisometropia, form sena finger deprivation, etc. If amblyopia is not diagnosed before the age of 8 years, it can lead to a delay** of timing and lifelong vision loss.

The diagnosis of amblyopia is mainly based on visual acuity, and the best corrected visual acuity in both eyes is lower than the visual acuity of the corresponding age, and this low visual acuity cannot be explained by other **. The specific modality depends on the type of amblyopia, including spectacle correction, occlusion of the dominant eye, or atropine suppression, etc., and any amblyopia must be addressed, and surgery is required if there is a form deprivation factor.

Typical symptoms. The effects of amblyopia on vision are multifaceted, the most important being lower-than-normal vision;

The child often tilts his head and squints when he looks at sensitive things;

Children with constant esotropia or exotropia may have strabismic amblyopia;

Some children with amblyopia have incomplete or even missing spatial stereopsis development, cannot correctly judge depth, and are prone to tripping when walking.

Accompanying symptoms. In addition to decreased external vision, patients with amblyopia may have other physical and mental problems that are easily overlooked, including poor hand-eye coordination, tripping and stumbling when walking, visual information processing disorders, and dyslexia, which may manifest as slow reading speed and poor comprehension.

Amblyopia is a patient who cannot reach after vision correction, generally there is no organic change of the eyeball, and the general manifestation is the blurring of vision. Amblyopia is a common ophthalmic disease, usually in children or infants. The symptom of the disease is that vision is lower than normal, including uncorrected visual acuity and corrected visual acuity.

The cause of amblyopia is usually due to the impaired development of retinal function due to occlusive factors in the eyes during the critical period of vision development, so the best corrected visual acuity of both eyes or one eye is lower than normal. Common causes of metaphysical excavation mainly include monocular strabismus, magnificente refractive error, anisometropia, congenital internal leukarhall deficiency, and congenital corneal opacity. For this disease, it is recommended to detect it early, as early as possible, and if the age of the disease is relatively early, it is possible that the situation will return to normal.

1.Amblyopia is generally congenital, often related to myopia and eye disease genetics;

2.The main manifestations of amblyopia are: unclear or inaccurate recognition of things, such as poor discrimination of small things, such as the recognition of grid lines that are slower than those of people with normal vision, so sometimes wear beads for amblyopia, so as to strengthen the recognition of small objects;

3.It is better to find amblyopia and start at the age of 2-3, otherwise it will be delayed and affect the effect of **;

4.Amblyopia will have a huge impact on future work and learning, early, targeted, patience is key, not a few months can be over;

5.The methods and means of amblyopia are generally relatively simple, and it is easy to do, and some are still a little fun, and it is very important to adhere to them;

6.Amblyopia** results in myopia.
