Abstract: the retinal tissue of high myopia becomes fragile due to degeneration and atrophy, which is very easy to make retinal detachment. Ocular trauma will cause eye damage and increase the probability of retinal detachment. Therefore, in daily life, we should pay attention to protect our eyes from trauma. When
highly myopic people play football, basketball and other antagonistic games, or participate in too intense sports such as sprint, the sudden impact of external force can promote retinal rupture and retinal detachment through vitreous conduction. The prevalence of myopia among
college students is as high as 80%, of which a considerable part is high myopia, and this phenomenon tends to increase. Some people think myopia doesn’t matter, and high myopia doesn’t matter. As everyone knows, patients with high myopia not only have myopia problems, but also live with a variety of complications; The higher the degree, the greater the possibility of inducing complications.
high myopia can lead to three major complications
1. Flying mosquito disease:
often appear in front of the eyes with the rotation of the eyeball, just like mosquitoes and flies flying, which is the reason for the liquefaction of the normal colloidal structure of the vitreous body.
2. Macular hemorrhage:
due to the continuous traction of the eyeball wall due to the enlargement of the eyeball, resulting in metabolic imbalance in the normal relationship between the fundus retina and choroid tissue, especially when the small blood vessels in the macular area are broken due to traction and other factors, it will cause macular hemorrhage and greatly damage the central vision. At this time, the patient realized that there was a fixed shadow blocking his line of sight. Although the bleeding can be absorbed after treatment, it will always leave spots more or less, affecting vision. There are also some patients with abnormal neovascularization in the macula, repeated bleeding, and more serious visual damage.
3. Retinal detachment:
high myopia is not only unable to see clearly, but also the most important thing is that the shape of the eyeball may change, that is, the anterior and posterior diameter may be lengthened. With the change of eye shape, the retina and choroid at the back of the eye will be pulled, resulting in the deformation of retina and choroid; If there is a hole, it may lead to retinal detachment, and the consequence is blindness. Generally speaking, for every 300 degree increase in myopia, the anterior posterior diameter of the eyeball increases by about 1 mm. Therefore, the higher the degree of myopia, the greater the risk of retinal detachment. According to statistics, about 70% of patients with retinal detachment are myopia, of which 30% ~ 40% are high myopia.
therefore, when people with high myopia suddenly have vision loss, and there are dark shadows fluttering in front of them, especially the flash feeling like lightning, or they consciously have a fixed dark shadow covering in front of them, they should go to the hospital for examination as soon as possible, which may be the precursor symptoms of diseases such as retinal detachment or macular hemorrhage.
these complications can be treated by modern medical technology. Floaters can be partially relieved by drug treatment, macular hemorrhage can be treated by drugs and photodynamic laser (PDT), retinal detachment can be treated by laser and surgery, but it may relapse after treatment.
high myopia do not take strenuous exercise
the following factors may increase the incidence of complications:
1. Eye trauma:
the retinal tissue of high myopia becomes fragile due to degeneration and atrophy, which is very easy to make retinal detachment, and eye trauma will cause eye damage, Increase the chance of retinal detachment. Therefore, in daily life, we should pay attention to protect our eyes from trauma.
2. Tired eyes:
keep staring at the TV screen or computer screen, which will also increase the probability of complications.
3. Do not pay attention to eye hygiene:
bacteria in the eyes will lead to eye diseases. Therefore, you should ensure the hygiene of your eyes and don’t rub your eyes with your hands.
4. Strenuous exercise:
when highly myopic people play football, basketball and other antagonistic games, or take part in too strenuous sports such as sprint, the sudden impact of external force can promote retinal rupture and retinal detachment through vitreous conduction. Therefore, highly myopic people should choose lighter sports.
in addition, people with high myopia must wear appropriate glasses, which can not only help to see clearly, but also help to protect their eyes; At the same time, we should regularly check eye diseases in regular hospitals to achieve early detection and early treatment.
