This topic topped the Weibo hot search list

This post-00 girl

Studying day and night for the exam

I feel like there's a black shadow moving around in my right eye lately.

Symptoms not relieved after a few days

Examination of the pupil revealed

There are 2 "holes" in the peripheral retina of her right eye.

Diagnosis of retinal tear

Many people began to doubt

Do you have the same problem with your eyes?

So, what is a retinal tear?

Eyes will also have holes?

The formation of retinal tears is the result of the combined degeneration of the retina and vitreous body.

Generally speaking, retinal tears are more common in people with high myopia or middle-aged and elderly people. This is related to the fact that the vitreous and retina of the elderly or people with high myopia often degenerate.

The girl in the news was severely myopic. She used her eyes frequently before the postgraduate entrance examination, which caused her eye muscles to tense and rotate continuously, pulling on the retina, which easily caused retinal tears.

High myopia is not just about not being able to see clearly

Let’s first look at some data:

A 2018 research report by the World Health Organization showed that there are 600 million myopic patients in China, and the myopia rate among young people ranks first in the world.

According to relevant survey data released by the National Health Commission in 2019, the overall myopia rate among young people nationwide is 53.6%. Among them, the myopia rate among high school students is as high as 81%. This shows that myopia has become a "popular" problem in my country.

Myopia, especially high myopia

In addition to affecting daily life

There are more dangers lurking

Myopia may cause pathological vision damage

and ocular complications

People with high myopia exceeding 600 degrees

The risk of developing cataracts increases fivefold

13-fold increased risk of retinal detachment

Risk of macular degeneration increased more than 800 times

The International Agency for the Prevention of Blindness has replaced cataracts with high myopia

The leading cause of blindness worldwide

Why does high myopia cause retinal tears?

The patient suffers from high myopia. As the myopia progresses, the eye axis continues to grow excessively, and the eyeball is like a balloon that is gradually blown up, causing the retina and choroid to gradually become thinner, making retinal degeneration and retinal tears more likely to occur.

Once a "hole" appears in the balloon membrane, further tearing is likely to occur. The same is true for the retina. If a retinal tear occurs and is not treated in time, the retina may detach under external stimulation, causing a sharp decline in vision or even blindness.

What are the signs of a retinal tear?

1. Seeing "floaters"

You may feel like there are small black "mosquitoes" flying around in front of your eyes. If the floating black shadow suddenly grows larger, it is likely that retinal detachment has occurred. When the vitreous body detaches, it tears the retinal blood vessels, causing blood cells and plasma components to enter the vitreous body.

2. Flash

When you look at a fixed direction, you will feel a flash, just like someone taking a picture of you with a camera with a flash. This is caused by the detached vitreous body pulling, which is one of the early symptoms of retinal detachment.

3. The “dark side” of vision

When retinal detachment occurs in a certain part of the eye, a curtain-like black shadow will appear in the corresponding part when you see objects, and you will feel like you are blocked when you see things. If the curtain-like black shadow becomes larger, it means that the range of the retinal detachment has expanded, and you need to go to the hospital for examination and treatment in time.

Protect your eyes, start today

To avoid problems with long-term close-up eye use, you can follow the "20-20-20" formula, which means that after reading, writing, looking at mobile phones and computers for 20 minutes, you should look up and look at a distance of 20 feet (6 meters) for more than 20 seconds.

You can choose to bask in the sun for at least 2 hours a day on your balcony or downstairs in the office. Let your eyes "bathe" in the sun and relax by looking far away. Watching videos and playing games for a long time will affect your eyesight. It is recommended to maintain a regular schedule and ensure adequate sleep. Increase the time for sleep and indoor activities, and the time for close-up use of the eyes will naturally be reduced.

At the same time, people with high myopia should prevent complications and avoid strenuous exercise or impact on the eyes: high jump, diving, disco, boxing and other high-impact sports, as well as bungee jumping, roller coasters, bungee jumping and other amusement facilities are not recommended.

Secondly, we should pay attention to regular eye examinations: it is recommended to have an eye examination under the guidance of a professional ophthalmologist every year or every six months, and the examination items include vision, intraocular pressure, eye axis, fundus, etc. Especially those who suffer from diabetes, hypertension, hypotension, and vascular diseases should have regular fundus examinations, and once problems are found, they should be treated in time.
