Why does myopia deepen step by step?

Abstract: in the process of eyeball enlargement, the sclera and choroid can grow continuously according to the signal requirements inside the eye, but the retina cannot grow with it. In order to adhere to the enlarged sclera and choroid, the retina will have holes or lattice degeneration around the retina, resulting in early lesions for retinal detachment in the future., The development of myopia is divided into several different stages, from pseudomyopia to true myopia, and then to the final high myopia. Different development stages have their own different characteristics: 1. In the stage of pseudomyopia, the eyeball is in a state of myopia due to spasm caused by excessive long-term contraction and regulation of ciliary muscle, but the ocular axis is normal. If the far vision is lower than the near vision, it is pseudomyopia, Primary and secondary school students’ myopia at the beginning is mostly pseudomyopia. If the spasm of ciliary muscle is relieved by drugs or other physiotherapy methods, the eyeball can return to its original state, block the development of myopia and prevent the development from pseudomyopia to true myopia. If there is no good prevention and treatment at this time, the retina will stimulate the continuous development of sclera and cause the growth of ocular axis, which will gradually evolve into true myopia., 2 in the stage of true myopia, the ocular axis of patients with true myopia is significantly longer than the original. According to expert analysis, the degree of myopia increases by 300 degrees for every 1mm increase in the ocular axis in patients with myopia. Generally, myopia below 300 degrees is called low myopia, those between 300 and 600 degrees are called moderate myopia, and those above 600 degrees are called high myopia., In the stage of high myopia, with the increase of ocular axis, the eyeball expands continuously, which is much larger than the normal eyeball. In the process of eyeball enlargement, the sclera and choroid can grow continuously according to the signal requirements inside the eye, but the retina cannot grow with it. In order to adhere to the enlarged sclera and choroid, the retina will have holes or lattice degeneration around the retina, resulting in early lesions for retinal detachment in the future., The development of

myopia is divided into several different stages, from pseudomyopia to true myopia, and then to the final high myopia. Different development stages have their own different characteristics:

1 pseudomyopia stage

spasm caused by excessive regulation of long-term contraction of ciliary muscle, so that the eyeball is in a state of myopia, but the ocular axis is normal, If the performance is that the far vision is lower than the near vision, it is pseudomyopia. Most of the myopia in primary and middle school students is pseudomyopia. If the spasm of ciliary muscle is relieved by drugs or other physiotherapy methods, the eyeball can return to its original state, block the development of myopia and prevent the development from pseudomyopia to true myopia. If there is no good prevention and treatment at this time, the retina will stimulate the continuous development of sclera and cause the growth of ocular axis, which will gradually evolve into true myopia.

2 true myopia stage

true myopia patients’ ocular axis increased significantly than before. According to expert analysis, the myopia degree increased by 300 degrees for every 1mm increase in ocular axis in myopia patients. Generally, myopia below 300 degrees is called low myopia, those between 300 and 600 degrees are called moderate myopia, and those above 600 degrees are called high myopia.

3 high myopia stage

patients’ eyeballs continue to expand with the increase of ocular axis, which can be seen in eye specimens that are much larger than normal eyeballs. In the process of eyeball enlargement, the sclera and choroid can grow continuously according to the signal requirements inside the eye, but the retina cannot grow with it. In order to stick to the increased sclera and choroid, there will be holes or lattice degeneration around the retina, resulting in early lesions for retinal detachment in the future.

and

myopia should be prevented and treated simultaneously. It is extremely important to cultivate good eye habits:

and

doctors suggest that

and

desks should be best placed in front of the window, and the light should be mixed with fluorescent lamps and incandescent lamps. You can eat something containing vitamin A, vitamin C and β- Carotene food.

take a break every half an hour, such as closing your eyes, overlooking, doing eye exercises, etc.

do not lie down or read in a dark light. Keep an appropriate distance between your eyes and the book. Generally, 30cm is the best.
