Congenital strabismus is broadly classified into exotropia, internal strabismus and paralytic strabismus, etc. Regardless of the type of strabismus, it does not heal on its own and most children require surgery. Only a small percentage of children can be treated conservatively to control the progression of strabismus. When can conservative treatment be chosen? First, if the child’s strabismus is not particularly large and the parents do not want to treat it surgically for the time being; second, some special types of strabismus; third, the child cannot cooperate with the examination and cannot determine the degree of strabismus, which makes surgery impossible; the above three cases can try conservative treatment. At present, the main means of conservative treatment are wearing glasses, binocular visual function training and Botox injection. The most common way is to wear lenses (farsightedness or trigeminal lenses) to control strabismus mainly by correcting the eye position. For children with strabismus with refractive problems, such as internal strabismus with high hyperopia, the internal strabismus may disappear after the child wears farsighted glasses, even without surgery, but the strabismus will still exist after the child takes off the glasses. Therefore, these children need to wear glasses continuously, and as they grow older, if the hyperopia can disappear completely, it is possible that the eye position will remain normal even after the glasses are removed, and the strabismus will no longer be present. For children who are clearly diagnosed with strabismus and have a small strabismus and do not want to have surgery, they can choose to wear a trigeminal lens to temporarily return the eyes to their proper position, which helps restore binocular vision and eliminate “double vision”. However, wearing trigeminal lenses can only control the progress of strabismus, but cannot cure it, and surgery is needed as soon as possible. In addition, wearing a trigeminal lens before surgery can help the surgeon determine the degree of strabismus and provide reference information for surgery design. There is no big restriction on the age of the child for wearing glasses. Generally, all children over 6 months old can wear glasses, and they should insist on wearing them from morning to night every day and take them off at bedtime. If the child does not cooperate with always taking off the glasses, the conservative treatment loses its meaning. After getting glasses, the child should return to the hospital for a review in the third month to see if the eye position has returned to normal after wearing the glasses, and continue to review every six months to a year to see if the glasses need to be adjusted. If you don’t review for a long time, there is a possibility that the prescription of the glasses does not match the real prescription, so your child will not be able to see and maintain the eye position, and wearing glasses will be ineffective. Parents should usually pay attention to supervise their children to insist on wearing glasses, if the glasses can not be worn, you can add leather bands on the legs of the glasses to help fix the glasses; you can also choose the child’s favorite color to increase the child’s interest in wearing glasses, to ensure the effectiveness of treatment. It is also important to pay attention to safety and prevent the glasses from breaking.
