Esotropia is a common pediatric ophthalmologic disorder that, if left untreated, can have a significant impact on the binocular visual function and appearance of the child. Binasal occlusion (BNO) is a non-surgical measure to alleviate the impact of esotropia. But there is no consistent theoretical basis for BNO and its therapeutic efficacy has been controversial. This study aimed to investigate the effect of BNO in the treatment of children with esotropia.
We performed a retrospective review of children with multiple types of esotropia who still had symptoms of obvious esotropia or the presence of visual diplopia after full refraction correction at the Affiliated Hospital of Yunnan University Hospital from October 2022 to September 2023. All the children were given BNO. Vision function and strabismic degree were examined before and after 3 months of BNO. The data were analyzed by Wilcoxon signed-rank test and Fisher's exact test.
The mean value of the strabismus before BNO was significantly different from the mean value of the strabismus after BNO for 3 months, including near strabismus [25.22±18.25 9.63±11.92 prism diopters (PD); P<0.001], and distance strabismus (23.65±17.45 9.27±12.47 PD; P<0.001). Twenty-six cases were markedly corrected, 6 cases were effectively corrected, 9 cases were invalid. There was no significant difference in the efficacy of BNO between the various types of esotropia (F=8.333; P=0.15). Fifteen children had diplopia before, and 14 children reported the disappearance of diplopia after 3 months, with an effective rate of 93.33%.
BNO is an effective non-surgical treatment measure, which can effectively reduce the strabismus degree of many types of esotropia and improve the visual double-image situation, providing a good basis for the establishment of the subsequent visual function.
内斜视是一种常见的儿科眼科疾病，如果不治疗，会对儿童的双眼视觉功能和外观产生重大影响。双眼鼻侧遮挡（BNO）是一种减轻内斜视影响的非手术措施。但BNO没有一致的理论基础，其治疗效果一直存在争议。本研究旨在探讨BNO治疗儿童内斜视的效果。
我们对2022年10月至2023年9月在云南大学附属医院接受全屈光矫正后仍有明显内斜视症状或存在视复视的多种类型内斜视儿童进行了回顾性研究。所有儿童均接受BNO治疗。在BNO治疗3个月前后检查视力功能和斜视度数。数据采用Wilcoxon符号秩检验和Fisher精确检验进行分析。
BNO治疗前斜视平均值与BNO治疗3个月后斜视平均值有显著差异，包括近斜视[25.22±18.25 9.63±11.92棱镜度（PD）；P<0.001]和远距离斜视（23.65±17.45 9.27±12.47 PD；P<0.001）。26例明显矫正，6例有效矫正，9例无效。不同类型内斜视之间BNO的疗效无显著差异（F=8.333；P=0.15）。15名儿童之前有复视，14名儿童报告3个月后复视消失，有效率为93.33%。
BNO是一种有效的非手术治疗措施，可有效降低多种类型内斜视的斜视度数，改善视重影情况，为后续视觉功能的建立提供良好基础。
