Be aware of a few misconceptions about myopia treatment Wearing a proper pair of eyeglasses is the best way to prevent an increase in myopia and maintain useful vision. However, wearing glasses is a difficult thing for many parents to accept. They worry about their children’s psychology, whether they will become more and more introverted; whether their future career choices will be affected. There is always the thought that there might be a way to get your child out of glasses overnight and never touch those darn glasses again. The child was given a lot of money to seek medical attention. In the end, not only did not remove the glasses, on the contrary, the deeper the glasses, and in some cases there are complications, which is exactly the myopia treatment of the misunderstanding. Here, pointed out a few misconceptions, to avoid myopic patients to take a detour. Studio ophthalmology Xu Yuan misunderstanding one: ciliary muscle paralyzing drug long-term use can treat myopia. Indeed, there is a part of myopia is due to the regulation of spasm (false myopia) caused by relaxation of the regulation of the ciliary muscle approach can be relieved, ciliary muscle paralysis medication with visual acuity may be improved or return to basically normal, but this part of the patient in the myopic population of not more than 5%. Dilated pupil optometry will find that a part of the people, this dilated pupil vision improvement, the next time there is still a chance to find that vision loss, dilated a pupil, may be maintained on a few weeks to a few months, and some even a dilated pupil, lifelong did not wear glasses. It is such a good thing that there are people who go on this misunderstanding. Always feel that their children are that very small part of the false myopia, even if there is no false myopia now, at any time there may be false myopia, a little medicine to prevent it will not be a problem. Now it is safe to say that very few children have taken the path from pseudomyopia to true myopia, and most children have not taken that path. Another pathway in the development of myopia is accommodation lag, and long-term use of medications that affect accommodation may also lead to accommodation lag. Regulatory lag is the opposite of regulatory spasm, and if there is no spasm and relaxing medications are still being used, are they being used incorrectly? It needs to be made clear that the wrong medication is being used. A highly selective M2 receptor blocker has been reported to control myopia progression, but it requires vitreous cavity administration and is still in clinical trials. The various ciliary muscle paralyzers currently in use are not highly selective, and the route of administration is unlikely to be effective and is not recommended for long-term use. Myth 2, convex lenses can cure myopia. Another method that can relax the adjustment is convex lenses. Convex lenses are able to reduce the adjustment and avoid the rapid deepening of myopia caused by hidden internal strabismus, and wearing convex lenses for a long period of time can also improve the naked eye vision. Especially in patients with mild ciliary spasm, the effect of one dilated pupil can be achieved after 40 minutes of fogging vision with +1.50Ds orthokeratology. Normal vision may not be achieved as much as with ciliary muscle paralyzers, because even fewer people have mild spasms, and wearing convex lenses has little effect on those with more severe spasms. Nonetheless, many people gravitate to him, hoping that he is one of this small group of people for whom wearing lenses will work. It is true that after wearing convex lenses, one has seen an improvement in vision in oneself or in others. The mechanism by which vision improves in most myopic patients after wearing convex lenses is now largely understood, and in addition to a slight relaxation of the ciliary muscles, there is also a partial increase in depth of focus. If you do not understand the depth of focus, you can think back to the popularity of the “magic mirror” small hole mirror why people will be fascinated, and then be scorned. It is the use of changing the depth of focus to improve vision. In fact, blindly wearing convex lenses to cure myopia can only repeat the mistakes of the “xx magic mirror”. Wearing convex lenses, only the existence of hidden myopia of myopia has a controlling effect, this group of people in myopia only accounted for less than 1/4, 1/4 of the people are sick, so that all go to take medicine, is not eaten the wrong. In fact, external occultation is also one of the triggers that promotes the development of myopia, and it is still under debate whether external occultation will occur when patients without internal occultation are retreated with convex lenses. Moreover, there are methods of controlling myopia with exotropia, so will obsessive wearing of convex lenses delay the chance of effective control? Myth 3: Improving naked eye visual acuity is beneficial for myopia control. There is a significant difference in the rate of progression toward myopia between a visual acuity of 0.6 or better and a visual acuity of 0.5 or less. Of course, the better the vision, the slower the progression of myopia. Finding ways to improve your child’s vision a bit and go down a slower path of progression is what we strive for. However, there are several undesirable situations, one is through training, the use of compensatory measures to improve vision, such as: squinting, head down, side vision, etc., these methods will aggravate astigmatism, and astigmatism is one of the factors that promote the development of myopia, but also because of over-training may lead to the elongation of the eye axis, aggravating myopia; the second is to contain a bit of tears to measure out of the visual acuity, such as: smoke, stimulation, massage and then immediately after the measurement of the vision, the results of these eyesight can only give the parents a false impression that the child’s eyesight, and the child’s eyesight, and the child’s vision. These visual acuity results can only give parents an illusion that the child’s eyesight is better, thus delaying the correct control measures; Third, unstable vision, whether it is drugs, training or stimulation to obtain good vision, as long as it is not stable, it may aggravate the development of myopia; Fourth, the visual acuity improvement that does not meet the target, such as: trying to find ways to still can not naturally see more than 0.6 in the rapid development of the channel, in the long term, the efforts are not pleasing to the eye. Currently there is only one way to consistently improve naked eye vision, and that is corneal reshaping. This method also adjusts peripheral defocus and has a definite control over myopia deepening due to peripheral myopia being less than central myopia. However, it requires wearing lenses every night and care to avoid damage to the cornea. Misconceptions in myopia treatment are far more than these. With a comprehensive understanding of the mechanism of myopia occurrence and development, it is possible to avoid going into the misconceptions. Even if you are not able to understand those profound truths, you should know that there is not only one kind of myopia. What works for this kind of myopia may still be harmful to that kind of myopia. If only one method is being used in treating all myopia, then it is time to pay attention.
