Abstract: the myopia degree of primary and middle school students increases continuously, and the increase range is shocking. 150-200 degrees per year, For many hospital optometry centers It is quite common for you to understand the latest characteristics of myopia. First, the incidence rate is increasing. In recent years, the incidence of myopia in China has increased dramatically. At present, the incidence of myopia in China is 33%, which is 1.5 times the world average of 22%. The myopia rate of Chinese students ranks second in the world. In Gabor, 28% of primary school students, 60% of junior middle school students and 85% of senior high school students. About 70% of the new cases of myopia occur in the stage of puberty., The proportion of myopia among middle school students has increased from about 15% in the 1970s to 55% in the late 1990s. In the 21st century, this proportion has rapidly increased to about 80%., II. The initial myopia degree is getting higher and higher. For students with low vision in the first physical examination, optometry is adopted to obtain the initial myopia degree. Statistics show that in the last ten years, the average value of initial myopia is increasing rapidly. Today’s primary school students have just found myopia, which is often up and down 400 degrees. Ten years ago, the average initial myopia was less than 200 degrees., It can be seen that students’ myopia shows a trend of younger age and deeper degree, and it is time for the whole society to pay attention to and take measures., Third, the degree is growing faster and faster. Do you understand the latest characteristics of
myopia? The incidence rate of
and
is increasing. The incidence of
and
has been increasing rapidly in China in recent years. At present, the incidence of myopia in China is 33%, 1.5 times of the world average of 22%. The myopia rate of Chinese students ranks second in the world, second only to Singapore, including 28% of primary school students, 60% of junior middle school students and 85% of senior high school students. About 70% of the new cases of myopia occur in the stage of puberty. The proportion of myopia among middle school students in
and
has developed from about 15% in the 1970s to 55% in the late 1990s. In the 21st century, this proportion has rapidly increased to about 80%.
2. The initial myopia degree is getting higher and higher.
for students with low vision in the first physical examination, optometry is adopted to obtain the initial myopia degree. Statistics show that in the last ten years, the average value of initial myopia is increasing rapidly. Today’s primary school students have just found myopia, which is often up and down 400 degrees. Ten years ago, the average initial myopia was less than 200 degrees.
it can be seen that students’ myopia shows a trend of younger age and deeper degree, and it is time for the whole society to pay attention to and take measures.
III. The degree of myopia of
primary and secondary school students is growing faster and faster. The degree of myopia of
and
primary and secondary school students is increasing continuously, and the increase range is shocking. 150-200 degrees per year,
the harm of high myopia
If a person has one kind of problem, I believe he will go to the hospital for a doctor’s diagnosis and treatment. But for suffering from myopia, many people still lack due attention. Medical research has confirmed that with the deepening of myopia, the incidence of various eye diseases will increase significantly, such as macular degeneration, retinal detachment and so on.
and
high myopia can cause many serious complications, most of which will lead to blindness. It is one of the common causes of blindness in adults, accounting for the sixth place in blinding diseases in China. Common types of complications: posterior scleral staphyloma (incidence rate: 77.1%); retinal atrophy, degeneration, hemorrhage and hole; subretinal neovascularization (incidence rate: 5% – 40%); retinal detachment, cataract, glaucoma (7-8 times higher than non high myopia); flying mosquito, etc.
Remind patients with high myopia that when you have decreased vision and black shadow fluttering in front of you, especially when you have a flash feeling like lightning, or when you consciously have a fixed black shadow covering in front of you, you should go to the hospital to find a specialist ophthalmologist for examination as soon as possible, which may be a precursor of diseases such as retinal detachment or macular hemorrhage.
