High myopia is harmful. How to find it in time

Abstract: high myopia can cause cataract and macular hemorrhage, which can significantly reduce vision. The most serious is retinal detachment, which can lead to blindness and eyeball atrophy. This is a terrible symptom of high myopia., High myopia does great harm, so myopia patients should find out whether there are symptoms of high myopia in time, so as to prevent and treat it in time. Today, let’s introduce how to detect high myopia as soon as possible., Causes of high myopia, 1 Pathological myopia (genetic factors). Due to the internal pathological changes in the eyes, it is hereditary, which shows that myopia continues to deepen and increases rapidly. If the degree of myopia increases by more than 100 degrees, or even more than 200 degrees, or the accumulated high myopia reaches 2000 degrees within a year, it is likely to be pathological myopia. Generally, both parents have a history of high myopia, then the next generation will suffer from genetic diseases The probability is 65%., 2. Do not pay attention to eye hygiene and incorrect eye habits. When the lighting is too bright or too dark and the eye is used for too long, for example, office workers frequently touch the keyboard, but then habitually rub their eyes, it is easy to cause eye inflammation, or eye diseases such as trichiasis, ptosis and keratitis are not diagnosed and treated in time, which will aggravate myopia and change to high myopia. This reason is more common., 3. Improper glasses will also aggravate myopia. As an optical product, the spectacle lens is very delicate. Once the mirror surface is scratched, it will obviously affect the optical correction performance, which will not only improve the visual acuity, but also cause a series of visual fatigue., This leads to an increase in the degree of myopia. Therefore, good maintenance of glasses is also an important guarantee to ensure stable and normal vision., 4. Glasses “extended service”. The resin sheet should be replaced every 2-3 years. Most of the current glasses wearers lack the awareness of glasses maintenance, and do not realize the importance of glasses lens maintenance. When the glasses can not meet the vision requirements, they should timely go to the ophthalmology of the regular hospital for examination, correct the degree of myopia, replace appropriate glasses, and regularly recheck, so as to avoid long-term “hunger and thirst” of the eyes, excessive bending of the cornea and lens surface and aggravating the degree of myopia. It’s best to check your eyesight regularly, accept scientific and professional optometry, and judge whether the glasses match the eye power, so as to avoid the phenomenon of extended service of glasses as far as possible., 5. Glasses are of poor quality. Unqualified glasses not only can not correct myopia, but also promote the decline of vision and the development of myopia more rapidly. Some unscrupulous peddlers only care about money, lack the proper technical equipment and level, and sell low-quality glasses, which greatly deepens the degree of myopia.,

is very harmful to high myopia, so myopia patients should find out whether there are symptoms of high myopia in time, so as to prevent and treat it in time. Today, let’s introduce how to find high myopia as soon as possible.

causes of high myopia

1 Pathological myopia (genetic factors). Due to the internal pathological changes in the eyes, it is hereditary, which shows that myopia continues to deepen and increases rapidly. If the degree of myopia increases by more than 100 degrees, or even more than 200 degrees, or the accumulated high myopia reaches 2000 degrees within a year, it is likely to be pathological myopia. Generally, both parents have a history of high myopia, then the next generation will suffer from genetic diseases The probability is 65%.

2. Do not pay attention to eye hygiene and incorrect eye habits. When the lighting is too bright or too dark, and the eye use time is too long, for example, office workers frequently touch the keyboard, but then habitually rub their eyes, it is easy to cause eye inflammation, or eye diseases such as trichiasis, ptosis and keratitis are not diagnosed and treated in time, which will aggravate myopia and change to high myopia. This reason is more common.

3. Improper glasses will also aggravate myopia. As an optical product, the spectacle lens is very delicate. Once the mirror surface is scratched, it will obviously affect the optical correction performance, which will not only improve the visual acuity, but also cause a series of visual fatigue., This leads to an increase in the degree of myopia. Therefore, the maintenance of glasses is also an important guarantee to ensure stable and normal vision.

4. Glasses “extended service”. The resin sheet should be replaced every 2-3 years. Most of the current glasses wearers lack the awareness of glasses maintenance, and do not realize the importance of glasses lens maintenance. When the glasses can not meet the vision requirements, they should timely go to the ophthalmology of the regular hospital for examination, correct the degree of myopia, replace appropriate glasses, and regularly recheck, so as to avoid long-term “hunger and thirst” of the eyes, excessive bending of the cornea and lens surface and aggravating the degree of myopia. It is best to check your eyesight regularly, accept scientific and professional optometry, and judge whether the glasses match the degree of the eyes, so as to avoid the phenomenon of extended service of glasses as far as possible.

5. Glasses are of poor quality. Unqualified glasses not only can not correct myopia, but also promote the decline of vision and the development of myopia more rapidly. Some unscrupulous vendors are only concerned about money, lack the proper technical equipment and level, and sell low-quality glasses, which greatly deepens the degree of myopia.

6. Failure to wear glasses. Some people think that wearing glasses is inconvenient, unaccustomed and ugly, so sometimes they wear them and sometimes they don’t. In this way, the eyes are often in an unstable adjustment state, which will also gradually deepen the degree of myopia.

symptoms of high myopia

1. Exophthalmos: the symptoms of high myopia are: the anterior and posterior diameter of the eyeball increases significantly, some form posterior scleral staphyloma, the anterior chamber deepens, ciliary muscle atrophy, and some people have obvious exophthalmos.

2. Immediate shadow: immediate shadow is also a common symptom of high myopia. High myopia can cause vitreous degeneration, liquefaction, posterior vitreous detachment, etc. there are turbidity and floating objects in the vitreous. Patients can see flying mosquitoes, sparks and flashes.

3. Fundus changes: fundus changes are the most common symptoms of high myopia. Arc spots can be seen next to the optic papilla, the omentum is highly leopard shaped, omental atrophy spots and macular degeneration can be seen.

4. Visual acuity is significantly reduced: high myopia can cause cataract and macular hemorrhage, which can significantly reduce visual acuity. The most serious is retinal detachment, which can lead to blindness and eye atrophy. This isMore terrible symptoms of high myopia.

the harm of high myopia

1. Cataract: high myopia is easy to be complicated with cataract. People with high myopia will have cataract early, and the effect of cataract surgery is worse than those without a history of high myopia.

2. Retinal detachment: it is mainly characterized by sudden blurred vision, deformation and dark shadow occlusion, which can lead to blindness in severe cases. Once the retina is detached, surgery is needed immediately to avoid further deterioration of vision.

3. Atrophy of retina and choroid: eyeball dilation causes posterior scleral staphyloma, which makes the retina thinner and atrophy. When the atrophy involves the macula, macular hemorrhage and holes can appear, the visual acuity is seriously reduced, and there is a central fixed dark spot.

4. Glaucoma: according to statistics, many people with high myopia will develop glaucoma, and glaucoma is the second blinding eye disease at present, which is characterized by high intraocular pressure, progressive decline of vision and narrowing of visual field.

5. Flying mosquito disease: it is called vitreous opacity in medicine. It shows that when people look at things, there are dark shadows floating in front of them, just like mosquitoes flying. It is mainly caused by vitreous liquefaction. It is suggested that myopic patients with flying mosquito disease should regularly check the fundus and pay attention to the health of the retina.

diagnosis of high myopia

1. Dilation of pupils: in order to examine high myopia in detail, eye fluid must be used to dilate the pupils in order to clearly display the vitreous and retina.

2. Indirect or direct ophthalmoscopy: for those with severe vitreous opacity, the application of direct ophthalmoscopy often can not clearly show the fundus, so indirect ophthalmoscopy is required. The eyeground mirror has strong light, binocular monocular vision and good three-dimensional feeling. It does not need to adjust the lens degree. It focuses by the distance between the convex mirror and the eye. It can also see the eyeground for those with mild to moderate vitreous opacity, especially for the case of refractive interstitial opacity.

3. Trihedroscopy: it is mainly used to check the details of the peripheral part of the retina, such as lattice degeneration, small holes in the peripheral part, whether there is detachment in the macular area, the connection between the hole area and the vitreous body, etc. But it is not easy to see when the refractive stroma is cloudy.
