Is myopia still rising in adulthood? Beware of fundus lesions!

Abstract: high myopia is also divided into physiological high myopia and pathological myopia. Physiological high myopia no longer deepens the degree of myopia, and the corrected visual acuity can reach 1.0, and there is no obvious difference from normal people from the fundus.

many patients with myopia should have such a concept:

only the degree of children will rise. With the growth of age, vision will tend to be stable, and the degree of glasses will no longer increase. However, whether adults or minors, if they use their eyes excessively and often make their eyes in a tired state, the degree of their eyes will increase. Therefore, those who stay up late and watch computers and mobile phones for a long time will generally have the possibility of vision loss.

moreover, the problem of myopia is not only rising, but also may develop into high myopia, causing other eye problems, such as retinal detachment, glaucoma and other fundus diseases.

then, how many degrees is high myopia?

and

generally regard myopia of more than 600 degrees as high myopia;

and

also define high myopia when the equivalent spherical mirror exceeds 800 degrees. The so-called equivalent sphericity of

and

is obtained by adding half of the myopia and astigmatism (equivalent sphericity = myopia + 1 / 2 astigmatism). Because many people with myopia have astigmatism, the use of equivalent spherical lens can better reflect a person’s real refractive state.

high myopia, what trouble may it bring?

due to the average increase of myopia by 300 degrees, the length of anterior posterior diameter of eyeball will increase by about 1mm. Therefore, as the degree increases, the eyeball will become longer and longer, making the eyeball wall thinner and thinner. Accordingly, the choroid and retina will become thinner, which will greatly increase the risk of blind eye diseases such as retinal detachment, maculopathy and glaucoma. Some problems such as

and

are difficult to avoid. We can only try to find out and start treatment as soon as possible through regular inspection of the fundus.

can high myopia cause fundus diseases?

in fact, not all high myopia will cause fundus changes, but high myopia is more likely to suffer from fundus diseases. When it comes to high myopia, people need to pay attention!

high myopia is also divided into physiological high myopia and pathological myopia. Physiological high myopia no longer deepens the degree of myopia, and the corrected vision can reach 1.0, and there is no obvious difference from normal people from the fundus of the eye. Pathological myopia, that is, there is a problem with the fundus, the degree of myopia continues to develop, and the eyeball will be longer and longer. Therefore, from the fundus, in addition to the thinning of the retina, there may be other diseases, and the corrected vision also continues to decline, which may lead to serious consequences. Therefore, the degree of myopia is increasing, so we should go to the hospital ophthalmology for examination in time. In addition, if there is a sense of flash and occlusion in front of you, you should see a doctor as soon as possible to check whether retinal detachment occurs, so as to avoid delaying treatment.

then, how to avoid myopia and deepen

1. The light should be sufficient and comfortable. If the light is too weak and the font can’t be seen clearly, you will see closer and closer.

2. It’s best not to use your eyes at close range for more than 6 hours every day, and let your eyes rest every 30 ~ 40 minutes.

3. Don’t get closer or lie down to read or play with your mobile phone, which is easy to cause excessive tension of ciliary muscles and myopia.

4. Do more outdoor sports: often look out and relax the eye muscles, which is beneficial to the health of the eyes.

5. Regular vision examination: Patients with abnormal vision should go to the hospital ophthalmology for further examination in time.
