High myopia is not terrible. You can see it yourself!

Abstract: the risk of open-angle glaucoma in patients with high myopia is 5-6 times higher than that in normal people, and the symptoms and signs are not obvious, which is easy to be ignored. Therefore, patients with high myopia should regularly check their eyes and measure intraocular pressure. Once glaucoma is suspected, they should go to a professional glaucoma specialist for diagnosis.

high myopia refers to myopia with myopia degree greater than 600 degrees. However, the difference between high myopia and ordinary myopia is not just the degree. As the eyes of patients with high myopia become larger and longer, the retina is also elongated and thinner. After extreme elongation, there will be holes like old clothes, causing a series of complications.

patients with high myopia may have one or more dark shadows in front of them, like mosquitoes flying, due to the earlier liquefaction of vitreous colloidal structure. Flying mosquito disease itself does not need to be cared about, but the process of vitreous liquefaction and posterior detachment may pull the subsequent retina to produce retinal holes, leading to retinal detachment. Therefore, patients with flying mosquito disease had better dilate their pupils and check the fundus.

retinal detachment

high myopia patients are prone to retinal holes due to retinal thinning and early vitreous liquefaction. The probability of retinal detachment is 7-8 times that of normal people. If the patients with high myopia have a sudden increase in the dark shadow in front of them, the dark screen in front of them is blocked, the sense of flash and the visual acuity decreases, they must see a doctor in time. Once retinal detachment occurs, they should be operated as soon as possible in order to get the best visual acuity recovery.

choroidal neovascularization

due to the thinning of ocular blood vessels and poor blood supply in patients with high myopia, blood vessels may occur in places where there should not be blood vessels. These blood vessels will not only destroy the macular structure, but also cause complications such as macular edema and macular hemorrhage, seriously damaging vision. Fortunately, most patients have a good response to intravitreal injection of anti VEGF drugs, timely diagnosis and treatment, and their vision can be restored to a certain extent.

macular hemorrhage

patients with high myopia may rupture small blood vessels in the macular area during eyeball enlargement, resulting in macular hemorrhage and sharp decline of central vision. Macular hemorrhage can generally be absorbed by itself without special treatment, but multiple bleeding may leave stains and affect vision.

macular membrane, macular hole, macular splitting

if these lesions occur in patients with high myopia, vision loss and visual deformation may occur. If the lesions are serious, surgery is needed.

cataract

high myopia patients have cataract earlier than ordinary people, and the operation is more difficult. However, cataract surgery is now very mature. High myopia patients can not only solve the problem of cataract after surgery, but also reduce the degree after surgery, It solves the problem that the visual object becomes smaller when wearing high degree frame glasses.

glaucoma

the risk of open-angle glaucoma in patients with high myopia is 5-6 times that in normal people, and the symptoms and signs are not obvious, which is easy to be ignored. Therefore, patients with high myopia should regularly check their eyes and measure intraocular pressure. Once glaucoma is suspected, they should go to a professional glaucoma specialist for diagnosis.

how to prevent the complications of high myopia?

for teenagers who are still in the key stage of eye development, the most fundamental prevention method is to control the occurrence and development of myopia. We suggest that parents must supervise their children’s eye habits, and conduct visual inspection regularly to find out the degree problem as soon as possible. At present, studies have shown that outdoor sports are effective in controlling myopia. Therefore, more outdoor sports such as running and football are very beneficial to controlling the occurrence and development of myopia. Fine eye activities such as table tennis and piano may accelerate myopia and need to be controlled appropriately.

for children with rapid progress of myopia, wearing OK glasses can delay the rapid increase of degree. Wear it at night, achieve good vision during the day, and do not need to wear glasses.

posterior scleral reinforcement is the application of human sclera and dural materials to implant into the back of the eyeball. The implanted materials are adhered to the posterior wall of the eyeball, which effectively limits the expansion of the eyeball, prevents the extension of the eyeball, promotes the formation of scleral neovascularization and strengthens the blood circulation of the eyes, so as to control the development of myopia. (the gospel of the first patient with high myopia after posterior scleral reinforcement in Hainan)

For adults who have developed high myopia, we suggest that the fundus of the eyes should be examined at least every year. If there are symptoms such as flying mosquito, flash sensation, decreased vision, visual distortion and so on, we should see a doctor as soon as possible. At the same time, patients with high myopia should avoid strenuous sports, such as diving, roller coaster, bungee jumping, boxing, high jump and other violent shaking sports, but jogging, swimming, climbing, diving, push ups, sit ups and other less strenuous sports can be carried out as usual. For pregnant women with high myopia, we recommend checking the fundus before delivery. If there are no fundus diseases such as retinal holes, we can try natural delivery.
