PURPOSE
To report and to analyze the efficacy of horizontal rectus muscle transposition and inferior oblique muscle weakening in terms of pattern correction for patients with V pattern.
METHODS
The review of the medical files identified 55 patients who had esotropia (ET) or exotropia (XT) with V pattern. The primary outcome measure was the amount of V pattern collapse (Δ).
RESULTS
Of the 55 patients (mean age 22.1 ± 9.5 years), 27 (49.1%) were males and 28 (50.9%) were females. The type of deviations was XT in 30 patients (54.5%) and ET in 25 patients (45.5%). Inferior oblique muscle weakening was performed in 43 (78.2%) patients, whereas horizontal muscle transposition was carried out in 12 (21.8%) patients in addition to recession-resection procedures. The amount of pattern was significantly reduced in both groups (P=0.01 for the horizontal offset group and P<0.01 for the oblique muscle weakening group).
CONCLUSION
Oblique muscle weakening surgery and horizontal muscle offset are effective in the correction of V pattern when the amount of pattern is under 30Δ.
目的
报告并分析水平直肌移位术和下斜肌减弱术对V型斜视患者的模式矫正效果。
方法
回顾病历，确定55例患有V型内斜视（ET）或V型外斜视（XT）的患者。主要观察指标为V型模式塌陷量（Δ）。
结果
55例患者（平均年龄22.1±9.5岁）中，男性27例（49.1%），女性28例（50.9%）。斜视类型为外斜视30例（54.5%），内斜视25例（45.5%）。43例（78.2%）患者行下斜肌减弱术，12例（21.8%）患者除行徙后-切除手术外还进行了水平肌移位术。两组的模式量均显著降低（水平移位组P=0.01，斜肌减弱组P<0.01）。
结论
当模式量小于30Δ时，斜肌减弱术和水平肌移位术对V型模式的矫正有效。
