What are the clinical manifestations of amblyopia?

What are the clinical manifestations of amblyopia? In my opinion, amblyopia generally refers to the best corrected visual acuity of one or both eyes that is lower than the visual acuity of the same age, but there are no organic lesions on the eye examination. The symptoms of amblyopia are mostly manifested as low vision, difficulty in seeing far and near, being slow in distinguishing the size, light and shade, and shape of objects, and seeing things at a significantly slower pace.

If you are supposed to see things, it will be blurry and affect your brain.

Amblyopia's best-corrected visual acuity is below the minimum for the patient's age, and symptoms associated with vision loss are exhibited in life, sometimes detected during routine vision screening.

1. The impact of amblyopia on vision involves many aspects, the most important of which is that the visual acuity is lower than normal.

2. Children often tilt their heads and squint when they look at things.

3. Children with monocular constant esotropia or exotropia may have strabismus amblyopia.

Fourth, some children with amblyopia have incomplete or even missing spatial stereo vision, unable to judge the depth of filial piety, and are easy to trip when walking.

Fifth, other symptoms.

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

Early symptoms of amblyopia:1Fear of light, children with amblyopia are often afraid of light, and they will be very irritable when they see light.

2.The eyeballs tremor, the eyes often go out and there are some abnormal throbbing.

3.Vulnerable patients will squint when they see things, and they will not see clearly when they see things, so they will unconsciously squint.

4.Bad posture, every time you need to see something with your eyes, the patient's head will unconsciously deflect or tilt in a certain direction, or the patient's chin will be depressed or raised.

5.Hand-eye coordination is particularly poor, and hand-eye coordination is poor and prone to collisions or falls.

6.When reading words, there will be an opposite or inverted disorder, often reading the wrong line, or when reading and writing, there will be some reverse or inverted phenomena.

7.Patients may have a hemitropia.

8.When looking at things at a close distance, patients will be relatively close when looking at things, mainly because they can't see things clearly.

9.Eye abnormalities, weak vision patients will have some manifestations such as drooping eyelids.

Amblyopia and myopia, farsightedness and astigmatism are different, many parents are easy to confuse them into a slow talk, many people think that amblyopia is myopia or farsightedness, the concept of amblyopia is not clear, the more important thing in amblyopia is strabismic amblyopia, most of the amblyopia and strabismus are related, the symptoms of amblyopia are generally photophobia, nystagmus and blurred vision, etc., and amblyopia should be timely.

Amblyopia manifests as macular under the eye and loss of sensation. Myopia binocular power of more than 250 degrees to consider anisometropia, amblyopia amblyopia if there is amblyopia, and if the patient has strabismus, it is recommended to consider glasses first, and if it is ineffective, it is recommended to actively operate **strabismus to prevent aggravation of amblyopia. Amblyopia is generally relatively easy before the age of 12, but it is relatively difficult to become an adult, and amblyopia needs to be trained in amblyopia.

One of the main symptoms of children's weakness is that their eyesight is worse than others, and their eye-hand coordination is poor, followed by the inability to cooperate well with the teacher's instructions at school.

The symptoms of amblyopia are:1Visual acuity and refractive abnormalities, 2

dyslexia, 3Ocular motility disorder, 4visual impairment, 5

Abnormal fixation. Physician's advice: Amblyopia symptoms of the eye without obvious organic lesions, and the best corrected visual acuity of one or both eyes is lower than the visual acuity of the corresponding age, which is called amblyopia, or the difference in vision between the two eyes is 2 lines or more, and the lower visual acuity is amblyopia.

Precautionary measures: If the above situation occurs, it is recommended to go to the hospital for medical treatment, and pay more attention to eye hygiene.

I would describe the symptoms in layman's terms, because I also have monocular amblyopia.

If you see things with amblyopia, it will be blurry, but this blur is not the same as the blurring of myopia. The blurring of amblyopia is first of all a little difficult to perceive colors (not that you can't distinguish colors, but the connections between colors transmitted to your brain by the environment you see are blurred), and there is no way to focus and see something carefully, and there is a feeling that you are trying to see clearly but are very powerless. And the perception of light will be weak, amblyopia and normal seeing the same thing, amblyopia is probably darker than normal as a whole, because there is less light perceived.

Typical symptoms. 1.Vision and refractive abnormalities.

Best-corrected visual acuity does not reach the lower limit of normal visual acuity for peers. There are no obvious organic lesions in the eye. 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.

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.Eye movement disorders.

The eye movement of the non-amblyopia eye is also worse than that of normal people of the same age.

4.Visual impairment.

Amblyopia has abnormal color vision function and light vision; decreased contrast sensitivity; Lack of stereoscopic vision.

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.

Other symptoms. At present, the diagnosis of amblyopia in China still uses the international standard eye chart to detect, the best corrected visual acuity is lower than the containment, or the difference between the best corrected visual acuity of the two eyes is two or more lines, it can be considered as amblyopia, and the age factor should also be noted, and the lower limit of normal visual acuity for children of different ages should be referenced. The lower limit of normal visual acuity for children aged 3 to 5 years is and the lower limit of normal for children aged 6 years and older.
