目的：分析间歇性外斜视(IXT)患儿双眼视觉训练后立体视觉恢复情况及影响因素。

方法：纳入2021年10月至2023年10月于本院接受治疗的IXT患儿166例(失访脱落2例，最终纳入164例)作为研究对象，其中眼位矫正手术双眼视觉训练后无立体视觉36例作为术后无立体视觉组，术后有立体视觉128例作为术后有立体视觉组。所有患儿均于全身麻醉下行眼位矫正手术治疗，术后均接受双眼视觉训练，持续训练6 mo。统计IXT患儿双眼视觉训练后立体视觉恢复情况，予以单因素分析、多因素Logistic回归分析法分析IXT患儿双眼视觉训练后立体视觉恢复情况的影响因素。

结果：术后无立体视觉发生率为22.0%。术后无立体视觉组年龄≥9岁、病程时间≥1 a、存在屈光参差情况的患儿占比较术后有立体视觉组更高(均P<0.05)。多因素Logistic回归分析结果显示，病程时间≥1 a、年龄≥9岁、存在屈光参差情况是IXT患儿双眼视觉训练后立体视觉恢复的影响因素(OR=1.470、1.626、1.539，均P<0.05)。

结论：年龄≥9岁、病程时间≥1 a、存在屈光参差情况是IXT患儿双眼视觉训练后立体视觉恢复的影响因素，临床可据此给予高危患儿针对性的干预措施，以改善IXT患儿双眼视觉训练后立体视觉恢复。

METHODS: A total of 166 cases of IXT children who were treated in our hospital from October 2021 to October 2023(2 cases lost their follow-up, and 164 cases were finally included)were included as the research object, taking 36 cases with no stereopsis after binocular vision training in eye position correction surgery as no stereopsis group, and other 128 cases as stereopsis group. All the children underwent eye position correction surgery under general anesthesia, and all received binocular vision training for 6 mo after surgery. The recovery of stereoscopic vision of IXT children after binocular vision training was counted, and the influencing factors of stereoscopic vision recovery of IXT children after binocular vision training were analyzed by single factor and multi-factor Logistic regression analysis.

RESULTS: The incidence of postoperative no stereopsis was 22.0%. The proportion of children with an age ≥9 years old, course of disease ≥1 a and anisometropia in the group without stereoscopic vision after operation was larger than the group with stereoscopic vision(all P<0.05). Multivariate Logistic regression analysis showed that the course of disease ≥1 a, age ≥9 years old and anisometropia were independent influencing factors for the recovery of stereoscopic vision in IXT children after binocular vision training(OR=1.470, 1.626, 1.539, all P<0.05).

CONCLUSION: Age ≥9 years old, course of disease ≥1 a, and anisometropia are the independent influencing factors of stereopsis recovery of IXT children after binocular vision training. Therefore, targeted intervention measures can be given to high-risk children to improve the stereopsis recovery of IXT children after binocular vision training.
