Myopic amblyopia and Hyperopia Amblyopia can’t be distinguished clearly

Abstract: myopic amblyopia and Hyperopia Amblyopia belong to amblyopia caused by ametropia. Nearly 60% of children are accompanied by hyperopia. The amblyopia of these children can be called Hyperopia Amblyopia; Secondly, nearly 20% of amblyopia patients are accompanied by myopia. The amblyopia of these children is called myopic amblyopia.

children’s amblyopia

everyone knows that myopia and amblyopia are two different eye diseases, but do you know? Amblyopia is also divided into myopic amblyopia and Hyperopia Amblyopia. Usually, clinically, you tell your parents that your child is myopic amblyopia or your child is Hyperopia Amblyopia. When it comes to these, the parents’ face is at a loss. What are they and what are the differences between them? Today, let’s follow Xiaobian to learn about it! What is the difference between myopia amblyopia and Hyperopia Amblyopia?

1. Proportion difference

myopic amblyopia and Hyperopia Amblyopia belong to amblyopia caused by ametropia. Nearly 60% of children are accompanied by hyperopia. The amblyopia of these children can be called Hyperopia Amblyopia; Secondly, nearly 20% of amblyopia patients are accompanied by myopia. The amblyopia of these children is called myopic amblyopia.

2. Pathogenesis difference

① from the perspective of pathogenesis, although Hyperopia Amblyopia and myopic amblyopia are amblyopia, myopic amblyopia generally occurs myopia first and then causes amblyopia. Most of them are bilateral. Generally, the visual acuity of both eyes is equal or similar. This type of amblyopia mostly occurs in young children with high myopia who fail to wear glasses in time. The reason is that children often use their eyes at close range for a long time when they are very young, resulting in overdevelopment of the eyeball, prolongation of the ocular axis, atrophy or functional inhibition of fundus cells, and finally amblyopia.

② patients with Hyperopia Amblyopia usually have hyperopia first and then amblyopia. The occurrence of hyperopia amblyopia is closely related to eye development. In early childhood, the shape of the eyeball did not develop to a normal level, the anterior posterior diameter of the eyeball was smaller than that of normal children of the same age, and the refractive ability was insufficient.

3. Rehabilitation difference

both myopia amblyopia and Hyperopia Amblyopia belong to ametropic amblyopia, and their rehabilitation principles are similar. On the one hand, patients need to exercise the function of eye muscles and fundus cells by adhering to amblyopia training, so that fundus cells can develop, but the training for patients with myopic amblyopia should not be too fine; On the other hand, we should improve the amount of eye support and help the eye absorb nutrients to promote the development of fundus cells. It should be noted that compared with Hyperopia Amblyopia, the rehabilitation of myopia amblyopia is more difficult and needs more attention. Therefore, both amblyopic children and parents should have enough patience, perseverance and confidence.

high myopia often causes moderate amblyopia, and the treatment effect is slightly poor.

severe amblyopia caused by some high and ultra-high myopia belongs to refractory amblyopia, and the treatment effect is poor, which may be related to the following factors: children and adolescents grow with age, the eye axis becomes longer, the degree of myopia deepens every year, the higher the degree of myopia, the more obvious the pathological changes of the eye, and the atrophy and thinning of retina and choroid of high myopia, especially ultra-high myopia, Pigment epithelial cells decreased or disappeared, accompanied by the disappearance of rod and cone cells. These pathological changes not only make it difficult to improve vision, but also may reduce vision, which partially offset the effect of amblyopia treatment.

and

although the therapeutic effect of general myopia amblyopia is worse than Hyperopia Amblyopia, the near vision is relatively clear and promotes the development of fundus, so severe amblyopia is rare. Children with hyperopia, especially those with high hyperopia, need adjustment to see far and near, which is easy to cause regulatory visual fatigue, so it is easy to cause severe amblyopia before correction, which is also the reason why the importance of routine visual acuity screening for preschool children has been emphasized in recent years; With the increase of age, the ocular axis increases and the hyperopia degree decreases year by year, so the effect of early intervention is better.
