Will myopia deepen in adults?

Abstract: it is well known that close eye use and high-intensity eye use can cause visual fatigue. If you are in the state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, which makes the eyes in the state of fatigue myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur.

visual fatigue

at present, the emergence of more and more “visual fatigue” people is the manifestation of the change of modern lifestyle. Long time close reading, reading too small words, long computer operation time, etc. will overuse the eye adjustment ability, which can cause visual fatigue symptoms such as eye swelling and pain, dry hair, blurred vision, heavy eyelids, and even headache, orbital pain, and even nausea and vomiting.

then, how does visual fatigue lead to myopia or deepen myopia? As we all know, close eye use and high-intensity eye use can cause visual fatigue. If you are in the state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, which makes the eyes in the state of fatigue myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur. For regulatory myopia, if it is not treated early, it will become true myopia, so we must pay attention to it.

pathological myopia

pathological myopia, its diopter generally exceeds 1000 degrees, up to 3000 degrees. Pathological myopia occurs earlier (between 5 and 10 years old) and progresses rapidly. It continues to develop after the age of 25. The degree of myopia can reach more than -15.00d. It is often accompanied by fundus changes and vision is not easy to correct. It is also called degenerative myopia. It is an eye disease characterized by progressive deepening of diopter, continuous growth of ocular axis, progressive damage to ocular contents and retinal choroid tissue, resulting in visual dysfunction. Its prevalence rate is 1% ~ 12%.

pathological myopia is a kind of high myopia, which does serious harm to visual function. Pathological myopia is mainly caused by genetic factors. Therefore, although some people are not engaged in the work of close vision, they will still get sick, and can have serious complications such as retinal degeneration, hole, retinal detachment, macular hemorrhage and so on.

and

pathological myopia complicated with fundus lesions have a gradual process from light to heavy. In case of retinal detachment, retinal degenerative holes often occur first. As long as the fundus examination is carried out regularly and in detail, the degenerative holes around the retina are found as soon as possible, and retinal photocoagulation is carried out in time, the occurrence of retinal detachment can be avoided, Visual function can be well protected. If retinal detachment occurs, surgical treatment is required, and macular hemorrhage requires fundus fluorescence angiography and optical coherence tomography for further diagnosis and treatment.

diabetes

and

, when the blood glucose level of diabetics increases to a certain extent, the sugar content in the eyeball will also increase, causing the aqueous humor osmotic pressure to decrease in the eyes, and the lens may be in relative “hypertonic” state due to the increase of glucose content, resulting in edema, resulting in increased refractive power and myopia symptoms. Diabetic patients can suddenly develop myopia, or their old presbyopia symptoms are relieved. The degree of myopia caused by diabetes is often unstable. When the diabetes is effectively treated and the blood sugar is controlled at a normal level for a period of time, the myopia symptoms will gradually reduce to disappear, and the patients can be restored to normal vision.
