Strabismus gets better naturally with age and does not require treatment. First, it is important to recognize that there are some cases of complete accommodative internal strabismus that will correct with age, and that such patients often have hyperopia and impaired visual function. Such complete moderate strabismus accounts for only a small percentage of the total strabismus, and for such patients, treatment measures such as glasses, amblyopia training and visual function training are required. However, for the majority of strabismus, surgery is usually required. Therefore, all strabismus need to be treated regardless of the type of strabismus. Another type of “internal strabismus” in children is caused by a flattened canthus or nasal bridge, which is called pseudostrabismus. This “internal strabismus” can disappear with age. The diagnosis of true or false internal strabismus in children should be made by an ophthalmologist.
