Abstract

Purpose: To evaluate the effect of recession with Y-splitting of the superior rectus muscle (SR) on correction of dissociated vertical deviation (DVD).

Methods: Twelve consecutive patients with manifest DVD greater than 10 prism diopters (PD) received 7-mm SR recession with Y-splitting, with concurrent treatment of any horizontal deviation. Preoperative and postoperative evaluation of ductions and versions, ocular deviation and pattern was done. A successful outcome was considered as 0 to 6 prism diopters (PD) of vertical and 0 to 10 PD of horizontal deviation.

Results: Surgery was performed on 19 SR muscles of 12 patients. Successful correction of DVD was achieved in all operated eyes (100%) after a mean follow-up of 6.9 ± 4.05 months. DVD became manifest in the fellow eye in 2 of 5 patients following unilateral surgery. Hypotropia (that became occasional after amblyopia therapy) was seen in one eye after unilateral surgery. Mild SR underaction was seen in 2 eyes and marked underaction in 1 eye postoperatively. Y-pattern was documented in 2 cases, V-pattern in 1 case, and X-pattern in 1 case postoperatively.

Conclusions: SR recession with Y-splitting could be a promising option for correction of DVD. Bilateral surgery is advocated even if unilaterally manifest. Further studies on larger series of patients are recommended to consolidate these preliminary results.

上直肌衰退与y分裂校正游离垂直偏差：一项前瞻性研究。

目的：评价上直肌y型分裂后退矫正游离性垂直偏差（DVD）的效果。方法：连续12例视盘屈光度大于10棱镜屈光度（PD）的患者行7 mm SR退行y -劈裂术，同时治疗任意水平偏差。术前和术后评估导管和版本，眼偏差和模式。成功的结果被认为是0至6棱镜屈光度（PD）的垂直和0至10 PD的水平偏差。结果：对12例患者的19块SR肌进行了手术。术后平均随访6.9±4.05个月，所有手术眼均矫正成功（100%）。单侧手术后5例患者中2例伴眼出现DVD。单侧手术后单眼出现低视（弱视治疗后偶发）。术后2眼轻度轻度轻度轻度，1眼明显轻度轻度轻度。术后出现y型2例，v型1例，x型1例。结论：SR退行伴y分裂是一种很有前途的DVD矫正方法。即使单侧出现，也提倡双侧手术。建议对更大系列的患者进行进一步研究以巩固这些初步结果。
