One minute to teach you the difference between Hyperopia Amblyopia and myopia amblyopia!

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.

may be no stranger to amblyopia, but there is little in-depth understanding of it. You know what? Amblyopia is also divided into myopic amblyopia and Hyperopia Amblyopia. What’s the difference between the two? Let’s talk about it briefly today.

the difference between myopia amblyopia and Hyperopia Amblyopia

1. The difference in proportion

myopia 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

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, and the higher the degree of myopia, the more obvious the pathological changes of the eye, High myopia, especially ultra-high myopia, atrophy and thinning of retina and choroid, reduction or disappearance of pigment epithelial cells, 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.

in short, Hyperopia Amblyopia refers to amblyopia caused by hyperopia. Patients with Hyperopia Amblyopia usually have insufficient eyeball development, and the length of eye axis is shorter than that of normal children of the same age, except for amblyopia problems, They often suffer from higher degrees of hyperopia (usually more than 300 degrees); myopic amblyopia is a amblyopia phenomenon caused by myopia. Myopic amblyopia patients usually have over developed eyeballs and longer axial length than normal children of the same age. In addition to amblyopia, they often suffer from higher degrees of myopia (more than 400 degrees).

It is suggested that parents should always pay attention to their children’s abnormal behavior

and

. Parents can also use some simple methods to find the signs of their children suffering from amblyopia, such as putting eye-catching items in front of their children and observing whether they can find them in time. Observe the child’s binocular and monocular gaze, and pay attention to whether he likes to get close when watching TV. Observe whether the child has abnormal head position when looking at things, such as whether he likes to look up, bow his head and look at things. Observe whether the child can look at objects stably. If the child’s eyes turn back and forth or tremble, there is the possibility of amblyopia. Children often fall when walking, and they can’t get things. It may also be that amblyopia affects their sense of distance when they can’t grasp objects.

and

can roughly understand the visual acuity of both eyes through the masking test. Parents can deliberately cover one eye and let their children look at objects with one eye. If their children are very quiet, they should go to the hospital for examination as soon as possible.

and

myopia have a greater impact on naked vision than hyperopia. Therefore, the initial diagnosis age of medium and high myopia is generally early, which is mostly found in preschool. Because they are still in the sensitive stage of visual development, the treatment of amblyopia in the initial stage has made rapid progress. However, some preschool children may be congenital myopia, and amblyopia may not be completely cured. Most school-age children are postnatal myopia, the degree of amblyopia is relatively light, the pathological changes of fundus are rare, and the cure rate will be higher. Therefore, the specific analysis of the specific situation can not be generalized. For Hyperopia Amblyopia, the older the age, the less obvious the effect.
