Abstract: Studies in different countries have shown that the risk of glaucoma in myopia is 2 ~ 4 times higher than that in non myopia, and most of the relatives of high myopia are open-angle glaucoma. Open angle glaucoma is a disease of irreversible damage to optic nerve and visual field caused by increasing intraocular pressure, which makes patients from visual field defect to blindness. Why does
say that high myopia may be blind?
1 the world is so big, who can guarantee not to be blind?
even if a person with eyesight of 1.0 can’t guarantee that he won’t be blind in the future! There are so many accidents in the world every day. Who can predict the future? No one can guarantee that he will not be blind, deaf or dumb in the future!
but: high myopia itself will not cause blindness! Any statement about blindness after high myopia is either ignorance or intimidation! Not to mention that more than 600 degrees of myopia will not be blind (without other diseases), that is, one or two thousand degrees of ultra-high myopia. No doctor said that he would be blind in the future?
2. High myopia is more likely to cause blindness than ordinary people’s
High myopia has the risk of blindness. In addition to natural and man-made disasters with the same low probability as normal people, patients with high myopia have a higher risk of retinal detachment, glaucoma, maculopathy, cataract, posterior scleral staphyloma and other diseases.
No.1 retinal detachment
due to scleral expansion and retinal degeneration, the rate of net detachment in patients with high myopia is 7 to 8 times higher than that in normal people! Fortunately, compared with glaucoma and keratoconus, retinal detachment can be saved and can be treated by freezing, laser and laser surgery. Of course, parents should not be careless. If this is found late and not treated in time, it will also lead to permanent blindness. If it is not congenital abnormal eye development, net off is mainly related to overuse of the eye.
parents with high myopia should not stay up all night playing with electronic products, Don’t exercise violently (including taking a roller coaster), lift less heavy objects, and don’t donate blood as much as possible (the donation of patients with high myopia will lead to insufficient blood supply to the eyeball and may cause net detachment). Basically, net detachment can be prevented.
will not die if they don’t die. Although net detachment can be cured, if the ambulance doesn’t come in time, it can only be resigned.
Net off symptoms: the disease of flying mosquitoes is aggravated, as if there were clouds and fog blocking in front of you, there is a sense of flash during eye movement, the visual object is deformed, and the visual acuity suddenly decreases.
Studies in different countries have shown that the risk of glaucoma in myopia is 2 ~ 4 times higher than that in non myopia, and most of the relatives of high myopia are open-angle glaucoma. Open angle glaucoma is a disease of irreversible damage to optic nerve and visual field caused by increasing intraocular pressure, which makes patients from visual field defect to blindness. The most terrible thing about
is that patients with open-angle glaucoma usually have no symptoms in the early stage and their eyes are not painful or itchy. Many people find it only during routine physical examination, which is already in the middle and late stage. They even cover one eye one day and find that the other eye is blind, and the treatment effect of late glaucoma is poor.
can be controlled if they are found early, treated actively and adjusted. So, high myopia and blind parents can check the eye fundus, IOP and visual field every year or half a year, especially those with diabetes, hypertension, hypotension and vascular diseases, and check regularly to
and NO3.. The parents of cataract
with high myopia are complicated by cataract because of prolonged ocular axis, degenerative fundus lesions and abnormal intraocular nutritional metabolism. However, this cataract usually develops slowly, but parents should not take it lightly.
although high myopia has a high risk of these diseases, it does not mean that it will be, but compared with normal people. For example, different people have different resistance to colds. Even if the risk is high, the proportion of glaucoma patients in patients with high myopia is low. The key of
needs to be discovered early! Early discovery! Early discovery!
eyes are swollen, dry, acutely decreased vision, acutely increased astigmatism, foggy vision, visual distortion, all kinds of eye pain and even dizziness (forehead swelling and migraine). So, parents with high myopia only need to eat less spicy food, eat less sweet food, exercise less and check regularly.
