Abstract: macula is a small area of the retina, which determines the acuity of vision. If the macula is damaged, the highest vision can only reach 0.1. High myopia may also cause macular atrophy due to the lengthening of the eyeball, which will also lead to vision loss., China is a big country with myopia. Moreover, the incidence rate of high myopia is very high in China. The prevalence rate is 6 in a small population. 9%。 High myopia must pay attention to follow-up observation, otherwise it may cause retinal detachment and risk of blindness., Experts remind that myopia over 600 degrees is high myopia. 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 retinal choroidal degeneration. Therefore, high myopia may develop into “pathological myopia”. 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., The macula is a small area of the retina, which determines the acuity of vision. If the macula is damaged, the highest vision can only reach 0. 1。 High myopia may also have macular atrophy due to the lengthening of the eyeball, which will also lead to the loss of vision. Retinal detachment and macular atrophy are two major causes of blindness caused by high myopia., High myopia must pay attention to follow-up observation. These patients should check the fundus at least once a year. The purpose of fundus examination is to observe the changes of retina. If retinal degenerative areas or holes are found, laser or surgical repair should be done in time to prevent further development of retinal detachment. If retinal detachment is operated in the early stage, the success rate is more than 90%. Therefore, early detection and early treatment are of great significance., When a person suffering from high myopia suddenly suffers from vision loss and has a shadow fluttering in front of him, especially when there is a flash feeling like lightning, or when he feels that there is a fixed shadow covering in front of him, he should go to the hospital for a specialist ophthalmologist as soon as possible, which may be a precursor of diseases such as retinal detachment or macular hemorrhage.,

when people with high myopia suddenly have vision loss and black shadow fluttering in front of them, especially when there is a flash feeling like lightning, or they feel that there is a fixed black shadow covering in front of them, they should go to the hospital for examination as soon as possible, which may be the precursor of diseases such as retinal detachment or macular hemorrhage.
