High myopia is a bigger thing than you think

Myopia has a great impact on personal appearance, career choices, and daily life. Compared with low and moderate myopia, in addition to affecting personal life, high myopia also increases a bit of risk. Why do you say that? 01Q: What is high myopia? Usually, according to the degree of myopia, the degree of myopia is divided into three categories: low myopia, moderate myopia and high myopia. ● Low myopia: degree of myopia ≤ 300° ● Moderate myopia: 300°≤ degree of myopia ≤ 600° ● High myopia: degree of myopia ≥ 600° In addition to high myopia, there is actually a high degree of myopia, which is more than 1000° Chao is highly myopic. 02Q: Why is there a high degree of myopia? (1) Genetic factors Both parents are highly myopic patients, and their children are almost also highly myopic. If one parent is highly myopic, the probability of their children being highly myopic will be more than half. (2) Environmental factors For high myopia patients with genetic probability, if at the same time due to improper use of eyes in the process of work, study, etc., the occurrence of myopia will be accelerated. 03Q: I already have a high degree of myopia. Will the degree of myopia continue to deepen? Generally speaking, after the age of 18, the degree of myopia will gradually stabilize. However, high myopia is different from medium and low myopia. Medium and low myopia generally does not increase or has a small increase in adulthood, while high myopia will always increase, and the increase varies from person to person. 04Q: Generally speaking, there are two types of high myopia: one is simple high myopia: although the degree is high, it gradually stabilizes after adulthood, and there is no visual impairment in the fundus. The other is high myopia, which often develops into pathological myopia: the degree of myopia continues to increase, the axial length of the eye continues to stretch, and various fundus complications that damage vision develop. When high myopia develops into pathological myopia, the following conditions may occur: (1) keratopathy (2) outward growth of the eyeball (3) macular atrophy, choroidal neovascularization, macular hole (4) retinal thinning and detachment, 05Q: Can high myopia be treated? First of all, it is clear that myopia is an irreversible behavior. Secondly, if it is simple high myopia, the vision can usually be corrected in the following ways: (1) Through optical correction, the patient can go to the regular medical optometry for optometry, wear suitable concave lens lenses, and perform high myopia correction. (2) Corneal refractive surgery. At present, the common corneal refractive surgery methods include femtosecond and full laser. This type of surgery has higher requirements on the corneal thickness of patients, and some patients with high myopia cannot use such surgical methods to correct their vision. (3) Intraocular refractive surgery, high myopia patients with insufficient corneal thickness and unable to do laser correction can choose intraocular lens implantation for high myopia correction. Currently, icl lens implantation is common. 06Q: How to prevent high myopia? (1) Start small and check regularly. For children with high myopia on both parents or unilaterally, it is necessary to develop good eye habits as soon as possible, and go to the hospital for regular check-ups. (2) Pay attention to early myopia and intervene as soon as possible. If myopia has appeared, you need to go to the hospital for correction in time, such as wearing glasses or orthokeratology lenses. (3) Develop good eye habits and avoid using electronic products for a long time. After using the eyes for a period of time, we can look into the distance, relax our eyes and relieve visual fatigue. High myopia is a blinding eye disease, and its risks cannot be ignored. Patients with high myopia need to pay close attention to the changes in the fundus and visit the hospital regularly to exclude or intervene the risk of fundus lesions as soon as possible.
