What causes amblyopia

There are many causes of amblyopia, which can be summarized as follows: pediatric strabismus, high hyperopia, myopia and astigmatism, congenital cataract, severe eyelid ptosis, and congenital optic center and optic nerve dysplasia.

Amblyopia and myopia are not a disease at all. Myopia is an eye disease caused by the excessive tension of the ciliary muscle, the eye adjustment muscle, or the elongation of the eye axis, and the vision can be corrected after wearing glasses, while amblyopia is a kind of visual function development retardation and disorder, often accompanied by strabismus and high refractive error. Eyesight with glasses cannot be corrected to normal eye diseases, and the two diseases are fundamentally different.

Amblyopia is much more harmful to children's visual function than myopia. Because myopia is only the loss of visual acuity when it is far away, and is not accompanied by other visual impairments, vision correction is not limited by age; However, children with amblyopia not only have low vision, cannot be corrected, cannot have binocular monovision function, have no stereoscopic vision, and cannot be competent for driving, surveying and mapping and fine work in the future, which not only affects the future of work, but also directly affects the quality of China's population.

Amblyopia may be caused by congenital genetic factors, congenital cataracts or congenital corneal opacity, but it is also related to the acquired lack of attention to eye protection, such as studying for a long time or looking at mobile phones and computers.

If there is a phenomenon of amblyopia, you should go to the ophthalmology department of the hospital in time for treatment, and take the best plan according to the diagnosis results. During the ** period, you should protect your eyes, avoid staying up late for a long time, and it is best not to look at your mobile phone or play with the computer for a long time.

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.

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.

Fatigue, lack of eye hygiene, and lack of eye care.

1. Congenital causes.

2. If your vision is not corrected when you are a child, you will slowly become amblyopia.
