Na KH, et al. - The development pattern and related factors of postoperative re-drift were analyzed by the researchers in the case of infantile esotropia. Following infantile esotropia surgery, a difference between the development pattern of exotropic and esotropic drift was noted. For determining the surgical outcomes of infantile esotropia, detailed preoperative assessment and close postoperative observation of deviations and refractive status would prove to be useful.
