| ［摘要］ 目的 探讨双眼视感知觉训练对间歇性外斜视（IXT）术后患儿双眼视功能和立体视觉恢复的影响。方法 招募2020年10月至2024年1月柳州市红十字会医院收治的IXT患儿132例，采用随机数字表法将其分为观察组（予双眼视感知觉训练）和对照组（予常规训练），各66例。两组均持续训练3个月。比较两组训练疗效，比较两组术前及完成训练后的双眼视功能。比较两组训练前（术后第1天）及完成训练后的水平融合范围以及远立体视和Titmus近立体视人数比例。结果 观察组总有效率高于对照组，差异有统计学意义（95.45% vs 78.79%； χ2=8.170，P=0.004）。与术前比较，完成训练后两组的双眼视功能为Ⅲ级的人数比例均显著升高（P<0.05），且观察组高于对照组，差异有统计学意义（P<0.05）。与训练前比较，完成训练后两组水平融合范围及远立体视和Titmus近立体视人数比例显著增加（P<0.05）。观察组完成训练后的远立体视和Titmus近立体视人数比例显著高于对照组（P<0.05），但两组水平融合范围比较差异无统计学意义（P>0.05）。结论 双眼视感知觉训练可有效改善IXT术后患儿水平融合范围、双眼视功能及立体视觉，从而提高手术治疗效果。 |

| ［Abstract］ Objective To explore the effects of binocular visual perception training on binocular visual function and stereoscopic vision of pediatric patients after operation for intermittent exotropia(IXT). Methods A total of 132 pediatric patients with IXT who were admitted to Liuzhou Red Cross Hospital from October 2020 to January 2024 were recruited. They were divided into observation group(receiving binocular visual perception training) and control group(receiving conventional training) by using random number table method, with 66 cases in each group. Both groups were continuously trained for 3 months. The therapeutic effect of the training was compared between the two groups. The binocular visual function was compared between the two groups before operation and after the completion of training. The horizontal fusion range and the proportions of the pediatric patients with distant stereoscopic vision and Titmus stereoscopic vision were compared between the two groups before training(on the first day after operation) and after the completion of training. Results The total effective rate of the observation group was higher than that of the control group, with statistically significant difference between the two groups(95.45% vs 78.79%; χ2=8.170, P=0.004). Compared with those before operation, the proportions of the pediatric patients with binocular visual function grade Ⅲ in both groups were significantly increased after the completion of training(P<0.05), and the proportion of the pediatric patients with binocular visual function grade Ⅲ in the observation group was higher than that in the control group after the completion of training, with statistically significant differences(P<0.05). Compared with those before training, the horizontal fusion range and the proportions of the pediatric patients with distant stereoscopic vision and Titmus stereoscopic vision in the two groups were significantly increased after the completion of training(P<0.05). The proportions of the pediatric patients with distant stereoscopic vision and Titmus stereoscopic vision in the observation group after the completion of training were significantly higher than those in the control group(P<0.05), but there was no statistically significant difference in the horizontal fusion range between the two groups(P>0.05). Conclusion Binocular visual perception training can effectively improve the horizontal fusion range, binocular visual function and stereoscopic vision of pediatric patients after operation for IXT, and therefore improve the effect of surgical treatment. |
