Many parents think
Amblyopia is poor vision
Wear glasses and you'll do
But in reality
Amblyopia is not just an eye problem
Also associated with the conduction of visual information
Related to visual perception in the brain center
Other words
Both eyeballs
The optic nerve is also the brain center
As long as there is a problem on one side
both can cause amblyopia
so
The first thing we need to know is, what is amblyopia?
Amblyopia refers to the optimal corrected vision of one or both eyes caused by abnormal visual experiences such as unilateral strabismus, refractive error, shape deprivation, or high refractive error during visual development that is lower than the normal level of vision in this age group, or the difference between binocular corrected vision is more than 2 lines, and the symptoms of organic lesions of the eye are excluded.
Lower limit of normal values for normal vision in children
The lower limit of vision for 3-year-olds is 0.5
The lower visual limit for children aged 4-5 years is 0.6
The lower visual limit for 6-year-olds is 0.7
The lower visual limit for children 7 years of age and older is 0.8
What are the typical symptoms of amblyopia?
□ the effect of amblyopia on vision involves many aspects, the most important of which is that the vision is lower than normal;
□ children often tilt their heads and squint when they see things;
children with □ monocular constant inverted or extroverted may have strabismus amblyopia;
□ some children with amblyopia have incomplete or even missing spatial stereo vision, cannot correctly judge the depth, and are prone to tripping when walking.
What are the possible accompanying symptoms of amblyopia?
Patients with amblyopia may have other physical and mental problems that are easily overlooked, including poor hand-eye coordination, easy tripping, visual information processing disorders, and dyslexia, which may manifest as slow reading speed and poor comprehension.
What are the dangers of amblyopia?
Amblyopia is a disorder of visual function development, often accompanied by strabismus and high refractive error. The main effects of amblyopia include:
1. Decreased vision: the harm of amblyopia is more serious than myopia, farsightedness, astigmatism and other refractive errors, amblyopia will lead to blurred vision, not timely treatment will lead to the child's stereo vision development is missing, amblyopia children not only have both eyes or monocular vision decline, but also affect the development of binocular visual function, children do not have perfect binocular visual function, no fine stereo vision.
2. Prone to eye fatigue: reading and studying for too long, there will be symptoms of eye fatigue such as dry eyes and pain, and even dizziness and pain, affecting normal life.
3. Cause psychological burden: Due to blurred vision, it affects normal learning and life, and it is easy to have psychological gaps and affect physical and mental health.
The key to treating amblyopia is early detection and early treatment, and the earlier the treatment, the younger the age, the more obvious the increase in vision.
Therefore, we recommend that parents take their children to the hospital for eye examination as soon as possible, establish refractive development files, early detection, early treatment, and avoid irreversible damage to children's eyes.
