To investigate the surgical results of patients having horizontal strabismus with A-pattern associated with superior oblique overaction (SOOA).
Twenty patients with horizontal strabismus (12 exotropia [XT] and 8 esotropia [ET] with no previous strabismus surgery) with SOOA-associated A-pattern were analyzed retrospectively. Motor success was defined as a horizontal deviation of 8 prism diopters (PD) or less, 6 PD or less of vertical deviation in all gazes, and no greater than 8 PD of A-pattern. Stereoacuity was measured using the Titmus test (Stereo Optical, Chicago, IL).
Sixty percent of patients had successful results at the final examination. No significant difference was found between the XT and ET patients in preoperative and postoperative horizontal deviations in the primary position, A-pattern collapse, or success rate (P >.05). Four patients had an induced postoperative vertical deviation. Among eight patients without stereoacuity preoperatively, four showed an average of 910 seconds of arc (40 to 3000 seconds of arc) after surgery.
Simultaneous surgery on the horizontal and SO muscles in patients with horizontal strabismus with SOOA-associated A-pattern can achieve a relatively high surgical success rate and restore binocular function.
探讨伴有上斜肌亢进（SOOA）的A型水平斜视患者的手术效果。
回顾性分析20例伴有SOOA相关A型的水平斜视患者（12例外斜视[XT]和8例内斜视[ET]，均未接受过斜视手术）。手术成功定义为水平斜视度为8棱镜度（PD）或更小，所有注视方向垂直斜视度为6 PD或更小，A型斜视度不超过8 PD。使用Titmus测试（Stereo Optical，芝加哥，伊利诺伊州）测量立体视锐度。
60%的患者在最终检查时手术结果成功。XT和ET患者在术前和术后第一眼位水平斜视度、A型斜视消失或成功率方面无显著差异（P>.05）。4例患者术后出现垂直斜视。术前无立体视的8例患者中，4例术后平均立体视锐度为910角秒（40至3000角秒）。
对伴有SOOA相关A型的水平斜视患者同时进行水平肌和上斜肌手术，可获得较高的手术成功率并恢复双眼功能。
