Abstract:
Objective:To investigate the status of binocular visual function before and after operation in children with intermittent exotropia.Methods:Eighty patients with intermittent exotropia admitted to Fuyang People′s Hospital from January 2018 to December 2019 were selected for surgical treatment, and the differences in orthotopic rate, binocular visual function, strabismus and stereoscopic sharpness before and after treatment were observed.Results:The orthostatic rate was significantly higher than that before the operation [88.8%(71/80) vs. 40.0%(32/80)], the undercorrection rate and overcorrection rate were lower than those before the operation [7.5%(6/80) vs. 36.2%(29/80), 3.8%(3/80) vs. 23.8%(19/80)], and there were significant differences ( P<0.05). The rates of simultaneous vision (Ⅰ grade), near stereopsis, fusion faculty (Ⅱ grade), and far stereopsis(Ⅲ grade) after operation were higher than those before operation [91.2%(73/80) vs. 26.2%(21/80), 17.5%(14/80) vs. 5.0%(4/80), 21.2%(17/80) vs. 3.8%(3/80), 33.8%(27/80) vs. 0], and there were significant differences ( P<0.05). The strabismus angle, stereoscopic vision sensitivity, fusion faculty degree after operation were lower than those before operation [(29.5 ± 2.8) Δ vs. (46.2 ± 3.1) Δ, (190.6 ± 19.4)° vs. (240.3 ± 18.5)°, (3.1 ± 0.8)° vs. (4.3 ± 0.6)°], and there were significant differences ( P<0.05). Conclusions:It is very important to adopt appropriate surgical methods for children with intermittent exotropia, which can promote the improvement of orthotopic rate, significantly improve the binocular visual function of children, and achieve ideal therapeutic effect.
