PURPOSE To determine the best treatment for dissociated vertical deviation (DVD). METHODS The authors investigated the postoperative results of unilateral surgery for DVD in 14 patients when the visual acuity difference between the two eyes did not result in a postoperative dominance switch. All patients underwent bilateral medial rectus recession for congenital esotropia. RESULTS With this unilateral surgical procedure, all patients showed a significant improvement of the DVD in the primary position. None of the patients developed hypotropia, anti-elevation syndrome, or inferior oblique overaction in the contralateral (dominant) eye, and no changes were observed in the contralateral eye. CONCLUSIONS Unilateral surgery for DVD in the non-dominant eye in case of strong fixation preference does not create a postoperative manifest DVD in the unoperated dominant eye.

双侧不对称分离垂直偏差的单侧手术与强优先固定。

目的 确定分离垂直偏差 (DVD) 的最佳治疗方法。方法 作者调查了 14 名患者在双眼视力差异未导致术后优势转换的情况下进行单侧 DVD 手术的术后结果。所有患者均因先天性内斜视接受双侧内直肌退缩。结果 通过这种单侧外科手术，所有患者的主要位置的 DVD 都有显着改善。所有患者均未出现对侧（优势）眼斜视、抗抬高综合征或下斜肌过度反应，对侧眼未观察到变化。结论：在强固视偏好的情况下，对非优势眼进行单侧 DVD 手术不会在未手术的优势眼中产生术后明显的 DVD。[J 小儿眼科斜视。2022;59(1):60-64.]。
