Strabismus is a common disease and we are often surrounded by people with strabismus, so when exactly should strabismus be treated? If possible, the earlier the better. The most important thing is to treat congenital internal strabismus, which is known as “funny eyes”, early. Many people think that you have to have your child’s vision checked before you can treat them, but this is wrong! Even if a child does not know how to check his vision, he can be treated. When the child is 3 to 4 years old, he or she will be able to say up, down, left and right, and some will be a little later. It is best to operate at the age of 4-5 years old, as the earlier the surgery, the better for the child’s stereopsis development. The surgery requires general anesthesia, and many parents are concerned about this, and almost everyone asks if general anesthesia will affect their child’s intelligence. This is a very strange statement, until now, general anesthesia has not been found to affect the child’s intelligence, where this statement comes from, no one knows. In China, there are usually three peak times for strabismus treatment: First, when you go to college, when you are on the golden list, you should have surgery quickly, you can’t go to college with strabismus. The second is to get married, a major life event, you have to get surgery afterwards. The third is to marry a daughter-in-law, to become an in-law, a lifetime of untreated strabismus, quickly cure treatment. However, these three time surgery, are cosmetic surgery, the development of stereopsis has no role, are too late, and adults do strabismus, the effect is not as good as children, back to the more it.
