How does pseudomyopia recover? What are the methods to treat pseudomyopia?

Abstract: simple pseudomyopia mostly occurs in adolescents with strong accommodation function. The accommodation tension or spasm is caused by excessive close eye use. Pseudomyopia can occur in the early stage of mild hyperopia, emmetropia and myopia. The clinical manifestation is that the far vision can return to normal after relaxation and adjustment.

is called pseudomyopia because of temporary vision loss caused by tension or spasm. The visual acuity decline of simple pseudomyopia is only temporary. It can be recovered after proper rest and relaxation. However, we should pay attention to and master some knowledge and methods.

pseudomyopia phenomenon

simple pseudomyopia mostly occurs in adolescents with strong adjustment function. The adjustment is tense or spasm due to excessive close eye use. Pseudomyopia can occur in the early stage of mild hyperopia, emmetropia and myopia. The clinical manifestation is that the far vision can return to normal after relaxation and adjustment. If the far vision cannot be completely restored, it cannot be called simple pseudomyopia.

optometry is a reliable method to determine whether it is pseudomyopia. Such as natural optometry (without mydriasis) there is myopia degree, and the optometry after mydriasis proves that it is mild hyperopia or emmetropia, that is, simple pseudomyopia. However, this situation is rare in clinic. The most common is myopia with pseudomyopia. There may be short-term pseudomyopia in the early stage of myopia, which fails to attract attention. Do not check until the far vision can not return to normal after rest. At this time, it is not simple

due to the inconvenience caused by mydriatic optometry, there are few epidemiological investigation reports on pseudomyopia. Some people have investigated 100 cases Natural optometry and mydriatic optometry were performed in 200 eyes, which were often used at close range. The results showed that 28 eyes (14%) were mild hyperopia or emmetropia (simple pseudomyopia), 172 eyes were myopia (86%), of which 45 eyes (26%) had no decrease in myopia after mydriatic optometry (true myopia), 127 (74%) of the eyes were myopic after mydriasis optometry, but there was still myopia (true and false mixed myopia). It can be seen that there were few simple pseudomyopia in myopia examination, even if there was mixed myopia.

three types of myopia:

1. Pseudomyopia

Most of them occur in teenagers with strong adjustment function. After a long time of close eye use, they have blurred far vision, and the far vision can return to normal after a period of rest. Myopia degree of natural refraction is less than 200 degrees, and emmetropia or mild hyperopia after mydriatic refraction. As long as you pay attention to eye hygiene, you can generally recover without glasses;

  2. True myopia

and

mostly occur in school age for a long time. Far vision tends to decline and will not fluctuate upward. The diopters of natural optometry and mydriatic optometry are similar, most of which are more than 200 degrees. At present, there is no cure for true myopia. Suitable glasses should be worn for the convenience of study, work and life;

  3. Mixed myopia

and

have poor far vision, There may be fluctuations (sometimes good and sometimes bad), but the fluctuations can not reach normal under normal vision. The natural refraction degree is mostly more than 200 degrees, and the mydriatic refraction degree is reduced, but it is still myopia. It shows that there are regulatory factors in true myopia. The glasses should be subject to the mydriatic refraction result, and the pseudomyopia degree should not be added to the myopia degree.

and

treatment opinions

from reality, simple pseudomyopia can recover naturally and prevent myopia as long as you pay attention to eye hygiene and don’t use your eyes too close. However, if you can’t use your eyes reasonably, any treatment of pseudomyopia can’t have long-term effect.
