Myopia that deepens 100 degrees of true myopia in 1 month is more serious and less common in clinical practice. Myopia deepening 100 degrees of pseudomyopia in 1 month is often not serious. If true myopia continues at this rate, the patient will soon develop high myopia, which may lead to more serious complications, such as retinal detachment, choroidal neovascularization, and other more serious blinding eye diseases. If pseudomyopia is present, it can be recovered through active treatment, and more serious complications usually do not occur. Therefore, it is recommended that patients seek timely medical treatment if they deepen 100 degrees of pseudomyopia. If deepened 100 degrees of true myopia, need to take timely preventive and control measures to minimize the speed of myopia development.
