Strabismus and amblyopia are common diseases that affect children’s vision, and according to a survey, the prevalence of strabismus and amblyopia among children and adolescents in China has exceeded 1%. Strabismus refers to the asymmetrical position of the two eyes, with one eye focused on the target while the other is off the target. Although strabismus can occur at any age, it is most prevalent in children between the ages of 3 and 6. There are many causes of strabismus, both congenital and acquired, such as trauma, inflammation, tumors, and blood circulation disorders. Amblyopia is defined as low vision, always below 0.9, regardless of glasses. Most amblyopia is caused by strabismus, high myopia, farsightedness, astigmatism that has not been corrected for a long time, a large difference between the refractive states of the two eyes, and something that blocks light from entering the eye for a long time during infancy. The eyes are the windows of the soul, the first of the five senses, and strabismus not only destroys the image of the human body and negatively affects the child’s mind, causing low self-esteem and loneliness, affecting the normal development of personality and psychology, but strabismus can also cause amblyopia. Both strabismus and severe amblyopia can seriously affect the visual function of both eyes, resulting in a lack of stereo vision. The lack of stereoscopic vision can cause difficulties in driving, operating precision instruments and performing fine operations, which can greatly limit the child’s ability to learn and choose a career as an adult. In addition, children with paralytic strabismus often adopt a tilted head and sideways face to eliminate double vision, which will affect the development of the child’s bones, and if the head position is not corrected in time, spinal curvature will follow. How to find out if a child has strabismus or amblyopia? Usually, it is important to observe whether the two eyes are symmetrical, whether both eyes are looking at the same time or whether there is a tilted head. It is also important to note that children who adopt strange postures to look at things may also be a manifestation of strabismus, for example, they like to turn their heads sideways and roll their eyes upwards, etc. If these manifestations indicate that they may have strabismus; if you find that your child often frowns, squints, or gets closer to see things clearly, you should be alert to whether your child has amblyopia and should go to the hospital for an early examination. In addition to correcting the eye position to improve the appearance, the treatment of strabismus is more important for functional treatment, including amblyopia treatment and the restoration of normal visual function of both eyes. During childhood, the visual system is in the vigorous stage of growth and development and has plasticity, the younger the age, the greater the possibility of restoring the function of binocular vision, therefore, the earlier the treatment effect of both strabismus and amblyopia, the better the effect, the treatment effect will be significantly reduced as the age grows, and it will be difficult to restore the normal function of strabismus and amblyopia after the development period is terminated. After the age of 14, the cure rate of amblyopia is only 1-2%, and after adulthood, the cure rate is almost zero. At this point, strabismus surgery can only improve the appearance of the eye. Many children with amblyopia suffer from lifelong regrets because of delayed treatment. In addition, it is important to emphasize that the treatment of amblyopia is a long-term process, and it is normal to see no obvious results in a year and a half, and it takes up to 7-8 years to be cured, so do not let your laziness cause great regret in your child’s life.
