目的：观察视觉功能训练配合手术方案治疗间歇性外斜视患儿的临床效果。

方法：回顾性研究。选取2022年1月至2024年12月苏州大学附属儿童医院收治的100例间歇性外斜视患儿，根据治疗方式分为两组。两组均给予间歇性外斜视矫正术治疗，基础组术后未配合视觉功能训练方案，视觉组术后配合视觉功能训练方案。评估两组术前，术后12 wk知觉眼位检查结果、视感知觉立体视功能检查、多焦视觉诱发电位结果、中文版斜视儿童生存质量量表(Child-IXTQ)评分以及斜视度差异。

结果：两组基线资料具有可比性。术后12 wk，两组水平与垂直知觉眼位偏移均较术前降低，且视觉组低于基础组(均P<0.01)。术后12 wk，视觉组精细与动态立体视恢复患儿均较术前升高，且视觉组精细与动态立体视恢复患儿高于基础组(均P<0.05)。两组术前与术后12 wk粗糙立体视恢复患儿比较无差异(均P>0.05)。术后12 wk，两组第1环与第2环潜伏期均较术前降低，且视觉组低于基础组(均P<0.01)。两组术前与术后12 wk第3环与第4环潜伏期比较无差异(均P>0.05)。术后12 wk，两组Child-IXTQ评分均较术前升高，且视觉组高于基础组(均P<0.05)。术后12 wk，两组33 cm眼位与6 m眼位斜视度均较术前降低(均P<0.01)，但视觉组与基础组比较无差异(均P>0.05)。

结论：视觉功能训练配合手术方案治疗间歇性外斜视可改善多焦视觉诱发电位，促进视功能恢复，提高生活质量。

METHODS: Retrospective study. A total of 100 pediatric patients with intermittent exotropia admitted to the Children's Hospital of Soochow University from January 2022 to December 2024 were selected and divided into two groups based on treatment modality. Both groups underwent intermittent exotropia correction surgery. The control group did not follow a visual rehabilitation program postoperatively, while the visual rehabilitation group did. The differences were compared between the two groups in preoperative and postoperative 12 wk results of perceptual eye position examinations, visual perception stereopsis function tests, multifocal visual evoked potential outcomes, Chinese version of the Child-International Quality of Life for Children with Strabismus(Child-IXTQ)scores, and strabismus angle.

RESULTS: The baseline data of the two groups were comparable. Both groups showed reduced horizontal and vertical perceptual eye position deviation at 12 wk postoperatively compared to preoperative levels, with the visual group exhibiting lower values than the control group(all P<0.01). At 12 wk postoperatively, the number of children in the visual group who recovered fine and dynamic stereopsis increased compared to preoperative levels, and this number was higher than that in the control group(all P<0.05). There was no significant difference between the two groups in the number of children who recovered coarse stereopsis preoperatively and 12 wk postoperatively(all P>0.05). Both groups showed reduced latency for the first and second rings at 12 wk postoperatively compared to pre-surgery, with the visual group exhibiting lower latency than the control group(all P<0.01). There was no significant difference in latency for the third and fourth rings between pre-surgery and 12 wk postoperatively in either group(all P>0.05). Both groups showed increased Child-IXTQ scores at 12 wk postoperatively compared to preoperatively, with the visual group scoring higher than the control group(all P<0.05). Both groups exhibited reduced strabismus angles at 33 cm and 6 m at 12 wk postoperatively compared to preoperatively(all P<0.01), but the visual group showed no difference compared to the baseline group(all P>0.05).

CONCLUSION: Combining visual function training with surgical intervention for intermittent exotropia can improve multifocal visual evoked potentials, promote visual function recovery, and enhance quality of life.
