The annual increase of 200 degrees, why is the number of myopia deepening after adulthood?

Dahe Health News reporter Liang Lulu

"Myopia is the same as height, and it is not very old at a certain age."

Many people, like Xiao Wen, believed that adulthood will become stable, so they use their eyes to watch TV series, Internet cafes to play games ...

However, a recent vision examination completely changed the view of Xiaowen:

In just one year, the number of myopia of Xiaowen increased from 225 degrees from the left eye to 450 degrees, and the right eye increased to 475 degrees.

How is this going?

Increased myopia after adulthood

Or pathological state

Nan'an Chao, an ophthalmologist at the Second Affiliated Hospital of Zhengzhou University, said that under normal circumstances, the vision is relatively stable after 18 years of age. If you do not have myopia at this time and keep your eyes reasonably, your myopia will generally not appear.

For adults who are already myopia and high degree, even if they are 18 years old, myopia will progress, because at this time, it is likely that highly myopia or pathological myopia will be formed.

The most typical manifestation of pathological myopia is that with the increase in age, the number of myopia will gradually deepen.

If the number of myopia increases by more than 100 degrees, or even more than 200 degrees within a year, or a cumulative high myopia of 2000 degrees, it is likely to be pathological myopia.

Some pathogenic myopia can stabilize the eye axis through the reinforcement surgery of the posterior membrane to control the deepening of myopia.

Crystal aging, hardening, or changes in the state of the whole body. For example, diabetes, the increase in blood sugar in the whole body may cause the refractive index of the crystal body to change, thereby generating refractive myopia, which is one of the reasons for deepening myopia in adulthood.

"Under normal circumstances, once adult patients have deepened myopia and the degree of growth is too fast, they should go to the ophthalmology department of the regular hospital for inspection as soon as possible to clarify the reasons for deepening the degree and conduct effective intervention and treatment." Nan'an Chao reminded.

High myopia patient

Check the bottom of the eye regularly

How can adults use eyes scientifically and prevent myopic number from continued to increase? Nan'an Chao said that whether or not it is adults, as long as the eyes are used for a long time, the eyes will cause visual fatigue and worsening vision.

To avoid excessive eyes, otherwise it will cause symptoms such as dry eyes, blurred vision, sour eyes, eye pain, tears and other symptoms.

When watching TV and mobile phone in the room, try not to turn off the lights, and you should pay attention to indoor light for a long time with your eyes. Because the too dark environment can make the pupils scattered, causing the eyes of the eyes to block and cause glaucoma.

For patients with high myopia, it is best to have an eye inspection once in half a year.

High myopia can cause lesions of the eyes, such as retinal cracks, macular degeneration, and retinal detachment. Regular examination can cause early detection and early treatment of the fundus lesions.

High myopia may also cause cataracts and secondary glaucoma. Therefore, patients with high myopia should wear glasses that are suitable for myopia for a long time. Do not engage in close -range and eye -catching occupations. Do not consume too much sugar. Pay attention to supplement vitamin A and ensure sufficient sleep.
