What are the characteristics of amblyopia? How does amblyopia develop?

Amblyopia generally refers to a condition in which vision is reduced and difficult to completely correct with lenses.

Amblyopia is generally divided into two types: educational amblyopia and medical amblyopia.

Educational amblyopia: refers to congenital diseases such as congenital cataract, bull's eye, optic nerve atrophy, microphthalmia, aniridia, albinism fundus, retinitis pigmentosa and retinopathy of prematurity, etc., no matter what, their vision cannot reach the above.

Medical amblyopia: refers to amblyopia that can be restored through ** and training.

The **important thing about amblyopia is early detection and early on**. If you have symptoms such as squinting your eyes, watching TV very close to the TV, looking at things with your face tilted, and closing one eye to see in a bright place, you should go for an eye examination. Children are also screened before they start school.

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

Amblyopia refers to the best corrected visual acuity lower than that applicable to people aged 5 years and above, and those below 5 years old should be lowered to: 4 years old 0 amblyopia.

8. The visual acuity of 3 years old and under 3 years old can be divided into amblyopia caused by obvious organic lesions and amblyopia caused by no obvious organic lesions. Amblyopia can form strabismus, and strabismus can lead to amblyopia.

In addition to strabismus amblyopia related to strabismus, amblyopia is also caused by refractive abnormalities and anisometropia. Refractive abnormalities cannot be corrected, even if the vision is not improved by increasing the illumination or enhancing the contrast of the fixation target. Amblyopia is divided into the following according to the degree:

Mild amblyopia: visual acuity; Moderate amblyopia: visual acuity; Severe amblyopia:

Visual acuity less than or equal to.

Amblyopia is inherited from parents' myopia, as well as environmental pollution factors, and fertility-related, etc., which are generally congenital, that is, the incomplete development of the macula area of the fundus, which is caused, so amblyopia is also eye remnant. Generally, it is difficult to improve after the age of 12, so amblyopia is a race against time, and you should hurry, the sooner the better, generally 3-7 years old is the best period.

The causes of amblyopia are: astigmatism, distraction, high hyperopia, high myopia, strabismus, etc.

It is more complicated, and it is generally divided into congenital and acquired!

It seems that the experts can't tell ...... clearly

1. Tilting your head or reading with a biased face is also a common symptom of amblyopia.

2. In daily life, if you always squint to see things, or only use one eye to see things, and the other eye can not pay attention to what you are looking at.

3. Amblyopia is often seen, such as paracentral fixation, that is, fixation on the target at a certain point of the retina other than the fovea. 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.

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.
