What are the risks of high myopia? What are the dangers of high myopia?

The hazards of high myopia are as follows:1High myopia requires wearing thick glasses, and its image will affect many career choices, such as fire disaster relief, rescue, etc., and cannot participate in special occupational activities such as police officers and drivers; 2.

From the perspective of physical health, high myopia may lead to diseases of the eye, including exotropia, epiretinal membrane, retinal detachment, eye hemorrhage, glaucoma, cataracts, etc., which may lead to vision loss and seriously affect daily life.

The main danger of high myopia is the gradual development of the eye axis. Imagine if the eye is a ping-pong ball, when the eye axis gradually grows into a goose egg or egg, the inner membrane will become very thin. In addition to the inconvenience of wearing thick glasses, the pathological change of the eye is that the retina and choroid are stretched very long, which may bring some relatively greater dangers, such as retinal detachment, which is a problem that patients with high myopia may pay attention to for a lifetime.

In addition to the relatively big problem of retinal detachment, there is also a very common phenomenon in patients with high myopia, called vitreous opacity, commonly known as floaters. Floaters are very common in high myopia, and it is difficult to completely cure floaters, which is also a relatively common problem that plagues patients with high myopia. In addition to the length of the eye axis, there may be lesions in the retina, and there may be lesions in the choroid, and cataracts occur earlier than normal in patients with high myopia.

Moreover, once the occurrence of cataract with high myopia, the development is often relatively rapid. The occurrence of cataract is often accompanied by a further increase in myopia, and the trend of increasing is accelerating, and the patient's vision will decline more obviously. Patients with high myopia often begin to have obvious cataracts around the age of 40.

High myopia refers to myopia with a degree of more than 600 degrees. In addition to seeing from a distance and seeing things clearly, there are symptoms such as floaters, floaters, and astigmatism, and there are also different degrees of fundus retinal changes, such as myopic arc spots, leopard fundus, macular partial hemorrhage or formation of neovascular membranes, and lattice-like degeneration of the peripheral retina; Moreover, compared with normal people, the risk of retinal detachment, tear, tear, and macular hemorrhage is much greater. The earlier a teenager develops myopia, the greater the risk of developing high myopia.

If a child develops myopia at the age of 6, the degree of myopia is stable until the age of 16-18. Myopia is irreversible, and in this process, if a child increases in myopia within 50 degrees, he or she is already at risk of high myopia by the age of 16-18. On the contrary, if the age of myopia in adolescents is relatively late, at the age of 13-14, even if they have myopia at this time, the risk of entering high myopia will be reduced a lot, and the risk of high myopia will be reduced a lot, so the prevention of myopia lies in the early stage.

The main hazards of high myopia are as follows:

1. The most prominent harm is the reduction of distance vision, and with the increase of myopia, the degree of distance vision reduction is more serious.

2. Vision fatigue, especially in highly myopic eyes, can cause eye fatigue after a short period of reading.

3. Changes in eye position, due to the destruction of visual function in highly myopic eyes, which leads to unclear vision for a long time, which can cause eye deviation, and severe eye position deviation requires surgery**.

Fourth, the expansion of the eyeball, because the eyes with high myopia are mostly axial myopia, the anterior and posterior diameters of the eyeball continue to elongate, which will cause the axial elongation.

5. Fundus changes, due to the excessive elongation of the eye axis, the high myopia eye can cause degenerative changes in the fundus.

We compare the eyeball to a balloon, the length of the eye axis is like blowing too much air in a balloon, the balloon wall will inevitably become thinner, and the eye axis of patients with high myopia becomes longer, which may cause some changes in the fundus.

Some are less severe, such as staphyloma in the posterior scleral sclera, leopard fundus, etc., which do not affect vision too much.

However, if macular foveal hemorrhage, subretinal neovascularization, etc., occur, vision will be affected.

In addition, vitreous liquefaction, posterior vitreous detachment, lattice-like changes around the retina, and macular hole may occur, resulting in retinal detachment.

The risk of cataracts and glaucoma is also significantly increased with high myopia.

Therefore, people with high myopia should have their fundus checked every year and intervene in advance if problems are found**.

High myopia will eventually lead to various lesions of the retina, such as retinal detachment, macular degeneration, macular splitting, and posterior scleral staphyloma, which will seriously affect the patient's visual function and eventually lead to blindness, and it is very tricky. Therefore, in highly myopic eyes, patients must pay attention to the occurrence and development of prevention and control. At the same time, it is necessary to protect the eyes from damage, regularly go to the hospital for follow-up observation, and prevent and control in time if there are early lesions.

High myopia can easily lead to fundus lesions, especially in foggy weather or winter, which seriously affects travel safety.

Myopia above 600 degrees belongs to high myopia, which will cause a variety of complications in addition to the loss of distance vision, such as premature vitreous opacity, posterior vitreous detachment, high myopic fundus changes, retinal tears, retinal detachment, etc., so it is recommended to refraction and wear glasses in time for high myopia, usually maintain good eye habits, and avoid excessive eye use; Clause.

2. The fundus should be checked regularly, and the fundus should be examined 1 to 2 times a year; Clause.

3. Avoid strenuous exercise to prevent complications such as retinal detachment.

The main danger of high myopia is the complications.

1) Vitreous, choroidal and retinal degeneration caused by abnormal ocular structure and nutritional disorders.

2) Macular degeneration atrophy and posterior staphyloma caused by axial lengthening, scleral elongation, and biomechanical abnormalities.

3) Amblyopia and strabismus caused by low visual acuity and dysfunction of accommodative convergence.

The biggest risk of high myopia is the possibility of heredity, which can lead to congenital vision problems in offspring, so pay attention to eye hygiene.

Due to the continuous stretching of the eyeball wall caused by the enlargement of the eyeball, the normal relationship between the retina and the choroid tissue of the fundus is metabolically disordered, especially when the small blood vessels in the macular area are ruptured due to traction and other factors, it will cause macular hemorrhage and greatly damage the central vision.

At this point, the patient will feel that there is a fixed black shadow blocking the view in front of them.

Although bleeding can be absorbed through menstrual bleeding, it will always leave more or less scars that affect vision. There are also some patients with abnormal neovascularization of the macula, repeated bleeding, and more severe visual impairment.

Don't worry too much about high myopia, just say that the risk of retinal detachment will be a little greater than that of normal eyes, but it does not mean that retinal detachment will occur 100%, so try not to do strenuous exercise in life, and bend over the heavy work. Also, get enough sleep and don't overuse your eyes. In terms of diet, you can eat more foods that clear the liver and clear the purpose.

Milk, walnuts, goji berries are fine.

If you can't see things clearly without glasses, there should be no other risks.

The biggest harm of high myopia is fundus lesions, such as the further development of high myopia can lead to macular hemorrhage, choroidal neovascularization, retinal degeneration, retinal tears, rhegmatogenous retinal detachment, etc., which can seriously damage visual function and eventually lead to blindness in patients. So why we do myopia prevention and control is to prevent children from becoming highly myopic and not to have these eye damages.

The main danger of high myopia is that it is easy to cause retinal detachment, macular splitting, macular degeneration, etc., which will seriously affect vision, and the risk of cataract and glaucoma is higher than that of ordinary people. Therefore, patients with high myopia should return regularly every year for ophthalmic examinations.

If you have been using your eyes too much, it is easy to cause rapid prescription**, resulting in high myopia. High myopia refers to myopia above 600 degrees, because almost all high myopia eyes have axial growth and significant thinning of the posterior polar sclera, so it is easy to produce many serious complications, most of which can cause blindness, and is the sixth blinding disease in China. It can also cause the following complications.

Floaters

In medicine, it is called vitreous opacity, which is manifested by a black shadow fluttering in front of a person's eyes when looking at things, just like a mosquito flying, mainly caused by vitreous liquefaction. It is recommended that myopia patients with floaters should have regular check-ups and pay attention to the health of the retina.

Retinal detachment

The main manifestations are sudden blurred vision, deformation, and dark shadows, which can lead to blindness in severe cases. Once the retina is detached, surgery is required immediately to prevent further vision loss.

Retinal and choroidal atrophy

Dilation of the eyeball, causing posterior scleral staphyloma, which thins and atrophies the retina. When atrophy affects the macula, macular hemorrhage, hiatus, severe vision loss, and central fixed scotoma may occur.

Glaucoma

According to statistics, many people with high myopia will develop glaucoma, and glaucoma is currently the second leading blinding eye disease, which is manifested by high intraocular pressure, progressive decline in vision, and narrowing of the visual field.

Cataracts

High myopia is prone to cataracts. People with high myopia will develop cataracts early, and cataract surgery will be less effective than people without a history of high myopia.

In addition to some of the complications described above, there will be:
