Why must myopia check the fundus? What is the difference between the structures of various myopia?

High myopia should be examined by fundus photography and intraocular pressure detection every six months, mainly to prevent common complications of high myopia-glaucoma, cataract, choroidal atrophy, retinal detachment and so on. In this way, even if the degree changes and complications occur, they can be found in time. Regular eye examination and fundus examination High myopia is examined at least once a year, and the higher the degree, the more frequent the examination. If there are symptoms such as shadow shaking, visual distortion and visual defects in front of you, it is an important "signal" of eye diseases, so you must seek medical attention in time.

There are many important optical parts in the fundus, including macula, optic nerve, optic papilla, optic disc and so on. Any part is damaged, which may bring blindness crisis! People suffering from myopia are prone to visual fatigue besides not being able to see distant objects clearly. Because you often squint at things, it will make the extraocular muscles and ciliary muscles excessively tense, which is easy to cause eye fatigue. After reading, writing and watching TV for a long time, myopia patients will feel symptoms such as dry eyes, eye socket pain, blurred vision, ghosting and serial reading, and even more serious symptoms such as dizziness, nausea and headache.

Myopia can be divided into true myopia and false myopia. Science has proved that pseudomyopia can be corrected, but true myopia may be permanent, so we should pay attention to the distinction and clearly grasp the development and formation stages of myopia. With the continuous increase of eye wheelbase, eyeball deformation becomes more and more intense. In the process of eyeball enlargement, many cracks will appear in the retina in order to fit the enlarged sclera, and lattice degeneration will appear around the retina, which are the early pathological complications of retinal detachment. If myopia develops to a high stage, we must pay attention to it. High myopia is already dangerous.

Usually, you must supplement eye nutrition, pay more attention to rest, keep enough sleep, pay attention to balanced nutrition, avoid using your eyes at close range for a long time, do more outdoor sports, and develop healthy eye habits at ordinary times.
