Abstract

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. [J Pediatr Ophthalmol Strabismus. 2022;59(1):60-64.].

单侧手术治疗双侧不对称解离性垂直偏斜并强优先固定。

目的:探讨游离性垂直偏差(DVD)的最佳治疗方法。方法:对14例双眼视力差异不导致术后优势转换的单侧DVD手术的术后结果进行分析。所有先天性内斜视患者均行双侧内直肌收缩术。结果:通过这种单侧手术，所有患者的主要位置的DVD都有了明显的改善。所有患者均未出现对侧(主)眼低视、抗抬高综合征或下斜过度活动，且对侧眼未见任何变化。结论:强烈固定偏好的单侧非优势眼DVD手术不会在未手术的优势眼造成术后明显的DVD。[J].儿童眼斜视，2014,59(1):60-64。
