Regardless of whether your child is nearsighted or not, you should pay attention to these four types of eye examinations!

Not long ago, the latest monitoring data from the National Center for Disease Control and Prevention showed that the overall myopia rate among children and adolescents in my country was 51.9% in 2022. Among students who already have myopia, mild, moderate, and severe myopia accounted for 53.3%, 37.0%, and 9.7%, respectively, and the proportion of severe myopia has decreased. Compared with previous years, the overall myopia rate among children and adolescents in my country has shown a downward trend, and the trend of myopia at a younger age has been alleviated, but the situation of myopia prevention and control remains severe. * As the "gatekeeper" of children's myopia prevention and control, parents need to pay attention to the four stages of their children's myopia development.

1. Take precautions against myopia if you haven’t already!

Hyperopia reserve is a protective factor for the eyes, which is equivalent to a buffer zone, preventing children from becoming myopic so quickly. If you still have the habit of overusing your eyes when your hyperopia reserve is depleted quickly, you may develop myopia. In general, hyperopia reserve is constantly decreasing, but it is usually not a straight line decline, and the speed of decline is different for each child.

2. Identify suspected myopia!

True myopia generally refers to axial myopia. Due to congenital or acquired factors, the eye axis becomes longer and exceeds the normal value. When parallel light from a distance enters the eyeball, its focus falls in front of the retina, making it impossible to form a clear image.

Pseudomyopia is temporary blurred vision caused by long-term overuse of the eyes, which leads to visual fatigue and excessive tension of the ciliary muscles . The main method to judge true and false myopia is ciliary muscle paralysis optometry (mydriasis optometry) . The essence of mydriasis optometry is to relax the fatigue caused by long-term excessive tension of the eye muscles. If there is no degree after mydriasis optometry, it is pseudomyopia and it is recommended to observe; if there is myopia, it is true myopia and it is recommended to wear glasses.

3. If you already have myopia, control it!

High-risk groups for high myopia mainly include those with abnormal eye development, family history of high myopia, and long-term bad eye habits. High myopia has a strong hereditary tendency. When a child's parents suffer from high myopia, their children are also very likely to suffer from high myopia. If you read with your head tilted, lying down, walking, or use your eyes in too bright or too dark light, you may also develop high myopia.

4. Remedies for severe myopia!

When the axial length of the eye of a patient with high myopia continues to lengthen, some changes may occur in the fundus.

If foveal hemorrhage or subretinal neovascularization occurs, vision will be affected. Vitreous liquefaction, posterior vitreous detachment, retinal lattice changes, macular holes, etc. may also occur, leading to retinal detachment. In addition, the risk of cataracts and glaucoma in patients with high myopia will also increase significantly.
