Abstract: Objective: To investigate the effect of binasal occlusion in the treatment of children with concomitant esotropia. Methods: In this propective clinical study, 21 children aged 3 to 10 years with nonaccommodative esotropia or partly accommodative esotropia who had more than +20△ esotropia after full refraction correction for 6 to 9 months at Xiamen Children's Hospital from January 2019 to July 2019 were examined. All the children were given binasal occlusion. Vision function and strabismic degree were re-examined every month. Data were analyzed by single factor analysis of variance. Results: The average strabismus was +33△±13△ before binasal occlusion. After binasal occlusion for 3 months, average strabismus was +21△±15△. Three cases were markedly corrected, 11 cases were effectively corrected, 7 cases were invalid. After binasal occlusion for 6 months, average strabismus was +18△±12△. Five cases were markedly corrected, 13 cases were effectively corrected, 3 cases were invalid. The difference was statistically significant (F=8.316, P=0.001). Conclusions: Binasal occlusion can effectively assist the treatment of concomitant esotropia in children.
