What you don’t know about blindness – high myopia

Abstract: myopia is divided into axial myopia and curvature myopia. Most of the clinical myopia is axial myopia. The normal eye axis is 24mm and 28 ~ 30mm. The eye axis of high myopia will be longer., As for blinding eye diseases, it is well known that cataracts can be restored by surgery, but 99% of myopia patients do not have the expected blinding eye disease – high myopia retinopathy, i.e. pathological myopia., Is high myopia so harmful? Many people said it was incredible. Let’s take a look at the problems that patients are generally concerned about!, What is high myopia?, In medicine, myopia is divided by degree, Degrees greater than 600 degrees (children > 400 degrees) ametropia is called high myopia, because this kind of myopia mostly has pathological changes of the eye; more than 900 degrees is ultra-high myopia, also known as pathological myopia. The cause of high myopia is not clear, and the occurrence of pathological myopia has a great genetic relationship. The acquired environment plays an important role in the pathogenesis of myopia. Why can high myopia cause blindness?, Almost all high myopia have the phenomenon of axial growth and posterior sclera thinning. The main pathological changes are the atrophy and thinning of retina and choroid, which are aggravated year by year, resulting in many serious complications. Such as retinal detachment and fundus hemorrhage may cause blindness., Will myopia continue to increase in adulthood?, The anterior posterior diameter of the eye is the axis of the eye, which will change. In adulthood, the development of the axis of the eye is basically stable. With the growth of age and improper eye habits, there will be certain degenerative diseases. Most people will have presbyopia and cataract in the middle-aged and elderly, and a few people will have low myopia in adulthood due to living and working habits.,

about blinding eye diseases, we all know cataract that can be restored by surgery, but 99% of myopia patients do not have the expected blinding eye disease – high myopia retinopathy, that is, pathological myopia.

high myopia is so harmful? Many people said it was incredible. For the problems of common concern to patients, let’s have a look!

what is high myopia?

in medicine, myopia is divided by degree, Ametropia with a degree greater than 600 degrees (children > 400 degrees) is called high myopia, because this kind of myopia mostly has ocular pathological changes; ultra-high myopia with a degree greater than 900 degrees is also called pathological myopia. The cause of high myopia is not clear, and the occurrence of pathological myopia is closely related to heredity. The acquired environment plays an important role in the pathogenesis of myopia.

Why can high myopia cause blindness?

almost all high myopia have the phenomenon of axial growth and posterior sclera thinning. The main pathological changes are the atrophy and thinning of retina and choroid, which are aggravated year by year, resulting in many serious complications. Such as retinal detachment and fundus hemorrhage may cause blindness.

will myopia continue to increase in adulthood?

and

the anterior and posterior diameter of the eyeball is the axis of the eye, which will change. After adulthood, the axis of the eye will basically develop stably. With the growth of age and improper eye habits, there will be certain degenerative diseases. Most people will have presbyopia and cataract in the middle and old age, and a few people will have low myopia in adulthood due to living and working habits.

but for people with high myopia, their visual acuity has been changing, the ocular axis is growing, and even irreversible consequences will occur due to improper use of eyes.

and

eye axis will change. What’s the matter?

myopia is divided into axial myopia and curvature myopia. Most of the clinical myopia is axial myopia. The normal eye axis is 24mm and 28 ~ 30mm. The eye axis of high myopia will be longer.

warm reminder

for high myopia, it is recommended to go to a professional eye hospital for fundus examination every year, early detection and early treatment is the last word.
