What exactly is the visual training that doctors say can ** amblyopia?
In the process of amblyopia**, in addition to wearing glasses to correct and cover-up**, many doctors also let children do visual training. What role does vision training play in amblyopia**? Does visual training work? Is it OK to do only vision training?
In fact, amblyopia is more than just vision loss. Vision loss is only one of our strongest perceptions, but often the real problem lies beneath the surface.
Amblyopia is a syndrome, in addition to the obvious problems of low vision, monocular inhibition, in fact, there are a number of potential visual function problems: such as crowding, insufficient accommodation, insufficient accommodation, poor eye tracking, etc.
Wearing glasses to correct or cover the eyesight cannot improve these problems of abnormal visual function, so the intervention of visual training is needed to gradually improve the visual function, so that the visual acuity can be steadily improved.
What is Vision Training?
Visual training refers to the use of optical or psychophysical methods to produce a certain cognitive load on the visual system of the eye, so as to improve the visual function and visual comfort of the visual system, and achieve the purpose of improving and repairing binocular vision abnormalities.
To put it simply, visual training is a type of training between the eyes and the brain, retraining the relationship between the brain and the eyes, like doing eye movements, which is a kind of training that continuously stimulates the brain's visual neurocognitive system.
What is vision training used for?
1.Correct refractive error and break through the plateau stage of amblyopia
Some children with amblyopia** have corrected visual acuity improved to 0For some children with amblyopia with poor accommodative function, wear glasses to correct refractive error, but because the accommodative function has not been effectively improved, it is difficult for him to turn the blurred image into a clear image, so that the vision improves slowly. At this time, visual training is needed to improve the child's ability to adjust.
2.Consolidate the effect of strabismus amblyopia** and prevent regression
Amblyopia children can improve their visual acuity to 10, but due to the mismatch of binocular accommodative function and poor accommodative ability of amblyopia, his brain will continue to use good eye fixation when looking at things, and give up poor eyes, so that vision will regress. Visual training improves the balance of various functions of both eyes, and makes the effect of amblyopia** more durable and stable.
3.Improve visual quality and effectively alleviate eye fatigue
Through targeted visual training, it can not only effectively train the ciliary muscle, change its working state, increase its muscle strength and movement speed and amplitude, so as to effectively improve focus, improve visual quality, and effectively alleviate visual fatigue; It can also slow down the growth rate of myopia in children, let the eyes move to exercise the adjustment ability of extraocular muscles, so that extraocular muscles are not easy to be elongated or deformed, so as to effectively prevent the occurrence of myopia.
What does vision training consist of?
1.Amblyopia training
The purpose is to improve the visual acuity of amblyopia, such as fixation training, visual acuity improvement training, disinhibition training, etc.
2.Conditioning training
The purpose is to improve the accommodative ability, such as accommodative sensitivity training, accommodative ability training, accommodative response training, etc.
3.Fusion training
For abnormal aggregate function, fusion disorders, and special types of strabismus, fusion training can be used to improve one's fusion ability.
4.Functional eye movement training
Improve the quality of functional eye movements such as eye following, saccades, and fixation.
Huizhou Mingkang Eye Hospital warmly reminds: In general, various training contents and methods can sometimes be applied to each other, such as amblyopia to a certain extent, you can add some fusion training, adjustment training, etc. to improve the visual balance of the eyes. The addition of fusion training and eye movement training in the process of accommodative training can improve the relationship and function of accommodative and aggregate linkage.
