Many myopic friends are concerned about myopia in adults will deepen? This question varies from person to person. Generally speaking, as adults grow older and spend less time using their eyes, their vision will stabilize and their glasses will no longer increase. But some diseases can also contribute to myopia deepening, worthy of attention. 1, visual fatigue The increasing number of “visual fatigue” people nowadays is a manifestation of modern lifestyle changes. When prolonged close reading, reading too small text, computer operation for too long are excessive use of eye regulation, can cause eye swelling, dryness, blurred vision, heavy eyelids and other visual fatigue symptoms, serious headache, orbital pain, and even nausea, vomiting. So how does visual fatigue cause myopia or make myopia deepen? As we all know, the formation of myopia is mainly due to close eye use and high intensity eye use, resulting in eye fatigue. If you are in a state of fatigue for a long time, without relief and adjustment, it will easily lead to ciliary muscle spasm, ciliary muscle contraction time is too long, so that the eyes are in a long-term fatigue myopia pathology, will occur in the regulatory myopia that is pseudomyopia. For regulatory myopia, if not treated early, it will become true myopia, so it must be taken seriously. Personal experience can be shared with readers: 18 years old before going to college with 1.5 vision in both eyes, entered medical school to read a variety of heavy medical books daily, resulting in sophomore year with 150 degrees of myopia glasses. Now in middle age, myopia is only 50 degrees weekdays without myopia glasses. The reason for this is naturally because excessive visual fatigue has led to 100 degrees of regulated pseudomyopia. In addition, there is another point that needs to be noted: unsuitable eyeglasses will also add importance to fatigue and myopia. Therefore, once you find that your existing glasses cannot meet your vision requirements, you should go to the ophthalmology department of a regular hospital for an examination, replace your glasses with the right ones, and have them reviewed regularly. However, it should be emphasized that myopia is not clearer the higher the glasses prescription is, but accurate medical optometry is a prerequisite, and the adjusted myopia part must be removed when prescription is made, and the corrected visual acuity of both eyes can reach 1.0. In the treatment of thousands of cases of myopia, some friends came to the clinic through medical optometry found that they wear too high a number of myopic glasses, so they often appear the phenomenon of visual fatigue. 2, pathological myopia pathological myopia, the refractive power of more than 1000 degrees, up to 3000 degrees. Pathological myopia occurs early (between the ages of 5 and 10 years) and progresses quickly, and continues to develop after the age of 25, myopia can reach -15.00D or more, often accompanied by changes in the fundus, vision is not easily corrected, also known as degenerative myopia. It is an eye disease characterized by progressive refractive error, continuous growth of the eye axis, and progressive damage to the eye contents and retinal choroidal tissue causing visual dysfunction, with a prevalence of about 1% to 12%. Pathological myopia is a type of high myopia and is a serious hazard to visual function. Pathological myopia is mainly caused by genetic factors, so even though some people are not engaged in close vision work, they can still develop the disease, and serious complications such as retinal degeneration, retinal detachment and macular hemorrhage can occur. As long as regular and detailed fundus examinations are conducted, retinal peripheral degenerative fissures are detected as early as possible and retinal photocoagulation is performed in time, the occurrence of retinal detachment can be avoided and the visual function is well protected. If retinal detachment occurs, surgery is needed. If macular hemorrhage occurs, fundus fluorescence angiography and OCT examination are needed for further diagnosis and treatment. 3. Diabetes Can diabetes cause myopia? When the blood sugar level in the blood of diabetic patients increases to a certain level,
The lens may be in a relatively “hypertonic state” due to the increased glucose content, and water may penetrate through the lens capsule and enter the lens cortex,
The lens becomes edematous, resulting in an increase in refractive power and myopia symptoms. Diabetic patients may experience sudden onset of myopia or reduction of existing presbyopic symptoms. The degree of myopia due to diabetes is often unstable, and when diabetes is effectively treated, the blood sugar is controlled at normal levels for a period of time,
When diabetes is effectively treated and blood sugar is controlled at a normal level for a period of time, myopia symptoms will gradually decrease to disappear, so patients can return to orthoptic eyes or need to wear presbyopic glasses when reading again. 4. Cataract Cataract is the gradual turning of the crystal body of the eye into yellowish-brown color, and the refractive coefficient increases due to the increase of crystal body density, so the refractive power of the crystal increases, as if the magnification of the magnifying glass suddenly increases, which makes the myopia degree rise continuously and the vision also gets worse. Myopic friends may also have increased myopia during the formation of senile cataracts, while friends without myopia do not need presbyopic glasses to read because of senile cataracts, and the degree of presbyopia is improved, as if they are rejuvenated, some people jokingly call this phenomenon “the second spring of vision”. For friends with high myopia to the age of fifty if you find their glasses suddenly deepen, it is likely to be the performance of cataracts, must seek medical attention as soon as possible. 5, glaucoma Speaking of glaucoma, many people tend to “talk about glaucoma”. Because glaucoma is a serious threat to vision and visual function, mainly related to the “atrial” circulation is blocked, the pressure inside the eye increased. If effective treatment is not taken, high eye pressure will compress the optic nerve, leading to gradual atrophy of the optic nerve and a gradual loss of visual field leading to blindness. Researchers have found that the prevalence of primary open-angle glaucoma is significantly higher in highly myopic eyes than in orthokeratology and mild myopia, and the higher the myopia, the more likely it is to be complicated by primary open-angle glaucoma. 600 degrees or more of high myopia is a highly significant risk factor for glaucomatous optic neuropathy. At the same time, the combination of high myopia with primary open-angle glaucoma causes an increase in intraocular pressure, which can easily lead to a further extension of the anterior and posterior diameters of the eye axis and a gradual increase in myopia. Here, we remind our friends with high myopia not to neglect the IOP, fundus optic nerve and visual field examination, and early examination and early diagnosis can prevent the problem before it happens. Nowadays, myopia is listed as one of the top three diseases in the world, and the World Health Organization has made scientific prevention and treatment of myopia an important part of vision care. Adults with myopia should maintain a good work and lifestyle, pay attention to eye hygiene, and have regular annual checkups to detect and treat related diseases as early as possible. Eye discomfort should be seen by an ophthalmologist at a regular hospital in time for early detection and early treatment as possible.
