The main effect of strabismus on children’s eyes is that the strabismus is automatically abandoned and visual development is stalled. When the child passes the sensitive period of visual development, which is from 3 to 6 years old, the visual nervous system is already “fixed”, and even if the strabismus is cured by surgery, it is difficult to improve the visual acuity. Strabismus also affects the child’s mental health. Children with strabismus may suffer from greater psychological stress, low self-esteem, introverted personality, and poor socialization. They may also encounter difficulties in choosing a job or a spouse in the future. The purpose of strabismus treatment is to treat amblyopia and establish binocular vision, i.e., stereopsis, in addition to cosmetic effects. Stereopsis is an advanced visual function of the eye, and many jobs in modern life require normal stereopsis. If you wait until your child is older to have surgery for strabismus, not only will the vision of the strabismus not improve, but the stereopsis function will not be restored. Therefore, once you confirm that your child has strabismus, you should immediately go to the hospital for examination and treatment, and should not delay.
