This study aims to compare the effectiveness of pencil push-up training and binocular vision training in treating post-operative mild under-correction in patients with intermittent exotropia.
A prospective cohort study was conducted, including patients who underwent surgery for intermittent exotropia at Children's Hospital of Nanjing Medical University between June 2022 and January 2023 and experienced post-operative mild under-correction (-8∆ to -15∆). Patients were divided into two groups: pencil push-up training group and binocular vision training group. All patients underwent measurements of exodeviation and stereoacuity at distance and near, sensory fusion, and fusion convergence amplitude. The data were analyzed using independent sample t-tests, repeated measures analysis of variance, and Chi-square tests.
There were no statistically significant differences in exodeviation at distance and near between the two training groups before the training. After 6 months of training, the exodeviation at distance and near achieved a significant decrease in both groups (P < 0.05), and the pencil push-up training group showed a similar distance and near exodeviation compared to the binocular vision training group (t = 1.58, P ＞ 0.05; t = 0.43, P ＞ 0.05). After 6 months of training, the binocular vision training group exhibited significantly superior stereoacuity and fusion convergence amplitude compared to the pencil push-up training group (P < 0.001).
Both pencil push-up training and binocular vision training are effective in reducing exodeviation in patients with post-operative mild under-correction of intermittent exotropia. However, binocular vision training demonstrates superior efficacy in restoring stereopsis and fusion convergence amplitude compared to pencil push-up training.
本研究旨在比较铅笔俯卧撑训练和双眼视觉训练在治疗间歇性外斜视术后轻度欠矫中的疗效。
前瞻性队列研究，纳入 2022 年 6 月至 2023 年 1 月在南京医科大学附属儿童医院接受间歇性外斜视手术且术后出现轻度欠矫（-8∆ 至-15∆）的患者。患者分为铅笔俯卧撑训练组和双眼视觉训练组。所有患者均行远距和近距外斜视度、立体视锐度、感觉融合和融合性集合幅度测量。采用独立样本 t 检验、重复测量方差分析和卡方检验进行数据分析。
两组患者在训练前远距和近距外斜视度无统计学差异。训练 6 个月后，两组患者远距和近距外斜视度均明显下降（P＜0.05），且铅笔俯卧撑训练组与双眼视觉训练组远距和近距外斜视度相近（t=1.58，P＞0.05；t=0.43，P＞0.05）。训练 6 个月后，双眼视觉训练组的立体视锐度和融合性集合幅度均明显优于铅笔俯卧撑训练组（P＜0.001）。
铅笔俯卧撑训练和双眼视觉训练均能有效减少间歇性外斜视术后轻度欠矫患者的斜视度，但双眼视觉训练在恢复立体视和融合性集合幅度方面优于铅笔俯卧撑训练。
