To evaluate the long-term efficacy of slanted lateral rectus recession in children for reducing distance and near exodeviation and near-distance deviation difference in intermittent exotropia with convergence insufficiency.
The medical records of 53 patients with convergence insufficiency intermittent exotropia who underwent slanted bilateral lateral rectus recession performed by a single surgeon and received follow-up for more than 12 months were retrospectively analyzed. Deviation angles at 1 day, 1 week, 1 month, 3 months, 6 months, and 12 months postoperatively and on the last visit were reviewed. Surgical success was defined as postoperative residual distance and near deviation angles ≤8 prism diopters and a difference between the near and distance angles ≤8 prism diopters.
The mean duration of follow-up was 24 months (range, 12 to 61 months). On the last visit, the residual deviation angles were ≤8 prism diopters in 75.5% for distance, 62.3% for near, and 81.1% for the near-distance difference. Surgical success was achieved in 31 (58.5%) patients, and none of them manifested limitations in eye movements or diplopia at the last follow-up visit.
Slanted lateral rectus recession is an effective surgical method for reducing distance and near exodeviation and near-distance deviation difference in intermittent exotropia with convergence insufficiency.
评估儿童斜向性外直肌后徙术在减少间歇性外斜视合并集合不足患者的远距离和近距离外斜视及近距离与远距离斜视度差异方面的长期疗效。
回顾性分析53例间歇性外斜视合并集合不足患者的病历，这些患者均由同一外科医生进行双侧斜向性外直肌后徙术，并接受了超过12个月的随访。复查术后1天、1周、1个月、3个月、6个月、12个月及最后一次随访时的斜视度。手术成功定义为术后远距离和近距离斜视度≤8棱镜度，且近距离与远距离斜视度差值≤8棱镜度。
平均随访时间为24个月（范围12至61个月）。在最后一次随访时，远距离残余斜视度≤8棱镜度的患者占75.5%，近距离为62.3%，近距离与远距离斜视度差值≤8棱镜度的患者占81.1%。31例（58.5%）患者手术成功，且在最后一次随访时均未出现眼球运动受限或复视。
斜向性外直肌后徙术是减少间歇性外斜视合并集合不足患者的远距离和近距离外斜视及近距离与远距离斜视度差异的有效手术方法。
