Children with intermittent strabismus may undergo surgery if their condition worsens, such as an increase in the frequency of strabismus or an increase in the size of the strabismus. The choice of surgery for a 10-year-old child with intermittent strabismus is based on the size of the child’s strabismus and the frequency of the strabismus. If the child has a large strabismus, a high frequency of strabismus, and if the child’s stereo vision is severely affected, surgery should be performed as soon as possible to avoid irreversible effects. It is recommended that children with intermittent esotropia should be seen in a hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
