What is the difference between myopia and amblyopia? Whose harm is greater?

Abstract: the impairment of visual function in amblyopia patients is much more serious than that in simple myopia patients, and the treatment process is long, delaying the treatment opportunity, it can not be cured for life; In simple myopia patients, visual function can be recovered even after correcting ametropia in adulthood., The main clinical manifestation of simple myopia is low vision when looking far, but normal vision when looking close. In general, as long as simple myopia patients undergo refractive correction, their near and far vision can reach a normal level, and most of them have good binocular visual function and normal stereovision. A small number of pathological myopia, anisometropia, high myopia and astigmatism have different degrees of influence on monocular vision and stereopsis. After correcting ametropia, most monocular vision and stereopsis of other simple myopia patients can reach the normal level. Amblyopia has the following main clinical characteristics, which are significantly different from myopia;, After correcting ametropia in amblyopia, Vision is still low: the main problem of these patients is that the visual system (mainly the visual cortex) has not been developed normally. There is no need to limit the time for the correction of myopia, and the treatment of amblyopia must be timely. It is generally believed that preschool is the best age for the treatment of amblyopia, at the latest in school age (6-12 years old), it is difficult to cure after 12 years old. In fact, the treatment process is the process of normal development of the visual system. Therefore, amblyopia must be treated during the development period of the visual system. At this time, the visual system has certain plasticity. Beyond this period, it cannot be completely cured. The course of treatment for amblyopia is quite long, even if the treatment starts earlier , the whole process of getting cured in school age is also long. In the process of treatment, doctors need to give correct guidance to parents and children, and parents need to cooperate closely. Children must strictly implement the doctor’s orders, return visit regularly, and adjust the treatment plan at any time according to their condition., The stereoscopic vision of amblyopia patients is damaged. Because the vision of one or two eyes of amblyopia patients has not been developed normally, their stereoscopic vision has not been developed normally, and the stereoscopic vision of most patients has been damaged to varying degrees or even lost completely, In monocular inhibition (almost blind) state, manifested as three-dimensional blindness. The spatial positioning function of amblyopia patients is defective. For example, the doctor takes a pencil with the nib vertically upward, and the patient also takes a pencil with the nib downward. If the patient’s NIB vertically contacts the doctor’s nib, they often make mistakes. While normal people can easily complete this action, Mistakes are rare. For another example, when amblyopia patients play badminton or tennis, there are significantly more receiving errors and more smashing errors than normal people., In short, the impairment of visual function in amblyopia patients is much more serious than that in simple myopia patients, and the treatment process is long, delaying the treatment opportunity, it can not be cured for life; In simple myopia patients, visual function can be recovered even after correcting ametropia in adulthood., The main clinical manifestation of

simple myopia is low vision when looking far, but normal vision when looking close. In general, as long as simple myopia patients undergo refractive correction, their near and far vision can reach a normal level, and most of them have good binocular visual function and normal stereovision. A small number of pathological myopia, anisometropia, high myopia and astigmatism have different degrees of influence on monocular vision and stereopsis. After correcting ametropia, most monocular vision and stereopsis of other simple myopia patients can reach the normal level. Amblyopia has the following main clinical characteristics, which are significantly different from myopia; After correcting ametropia with

and

, Vision is still low: the main problem of these patients is that the visual system (mainly the visual cortex) has not been developed normally. There is no need to limit the time for the correction of myopia, and the treatment of amblyopia must be timely. It is generally believed that preschool is the best age for the treatment of amblyopia, at the latest in school age (6-12 years old), it is difficult to cure after 12 years old. In fact, the treatment process is the process of normal development of the visual system. Therefore, amblyopia must be treated during the development period of the visual system. At this time, the visual system has certain plasticity. Beyond this period, it cannot be completely cured.

the treatment course for amblyopia is quite long.

Even if the treatment starts early, the whole process of getting cured in school age is long. In the process of treatment, doctors need to give correct guidance to parents and children, and parents need to cooperate closely. Children must strictly implement medical orders, return visits regularly, and adjust the treatment plan at any time according to their condition.

the stereopsis of amblyopia is impaired

because the vision of one or two eyes of amblyopia patients has not been developed normally, their stereopsis has not been developed normally, and the stereopsis of most patients has been damaged to varying degrees, or even lost completely, In monocular inhibition (almost blind) state, manifested as three-dimensional blindness. The spatial positioning function of amblyopia patients is defective. For example, the doctor takes a pencil with the nib vertically upward, and the patient also takes a pencil with the nib downward. If the patient’s NIB vertically contacts the doctor’s nib, they often make mistakes. While normal people can easily complete this action, Mistakes are rare. For another example, when amblyopia patients play badminton or tennis, there are significantly more receiving errors and more spiking errors than normal people.

in a word, the damage to the visual function of amblyopia patients is much more serious than that of simple myopia patients, and the treatment process is long, delaying the treatment opportunity, it can not be cured for life; The visual function of patients with simple myopia can be recovered even after correcting ametropia in adulthood.
