方法：收集2011-01/2012-12我科住院接受手术的A-V综合征106例，斜肌异常者70例，行斜肌减弱手术解决A-V征，无斜肌及上下直肌异常且V征斜视上下转相差>20^△、A型斜视上下转>15^△者26例，行水平直肌垂直移位半个至一个肌腱。而对于无明显斜肌及垂直肌异常且V征斜视上下转相差≤20^△、A型斜视上下转斜视度相差≤15^△者10例，仅行常规水平直肌手术。

结果：术后观察A-V征消失情况，无A-V征为正位； A-V征>10^△为过矫或欠矫。106例患者，V征消失75例，过矫5例，欠矫4例； A征消失15例，过矫3例，欠矫4例。水平斜视>±10^△为过矫或欠矫，正位85例，欠矫11例，过矫10例。

结论：A-V征主要由眼外肌方面的原因造成的，对于A-V征伴有斜肌运动异常患者，行斜肌手术，无斜肌运动异常及垂直肌异常者，行水平直肌移位术均能很好地矫正A-V现象，术后远近立体视恢复好。双眼斜肌减弱术能改变原在位眼位，对于伴有斜肌异常的A-V型斜视设计水平斜视手术量时应予以考虑。

METHODS: Clinical data of 106 caseswith A-V patterns strabismus in our hospital from January 2011 to December 2012 were retrospectively analyzed. Seventy patients with oblique muscle overaction were performed weakening oblique muscle surgery to treat A-V pattern. Twenty-six patients with no abnormality of oblique muscle and superior and inferior rectus muscle, and with >20^△ between gaze up 25° and down 25° in V pattern and with >15^△ between gaze up 25° and down 25° in A pattern were performed horizontal rectus muscle transposition to half to one muscle tendon. While ten patients with no obvious abnormality of oblique muscle and vertical rectus muscle, and with ≤20^△ between gaze up 25° and down 25° in V pattern and with ≤15^△ between gaze up 25°and down 25° in A pattern were only performed horizontal rectus muscle surgery.

RESULTS: No A-V patterns was defined asnormotopia and A-V patterns >10^△ was defined as overcorrection or undercorrection after surgery. In 106 cases, V pattern was corrected in 75 cases, overcorrected in 5 cases, undercorrected in 4 cases. A pattern was corrected in 15 cases, overcorrected in 3 cases, undercorrected in 4 cases. Horizontal strabismus >±10^△ was defined as overcorrection or undercorrection after surgery. Eighty-five cases were corrected, 11 cases were undercorrected, and 10 cases were overcorrected.

CONCLUSION: A-V patterns strabismus was caused mainly by abnormal extraocular muscle. A-V patterns with abnormal oblique movement were treated by oblique surgery and A-V patterns with normal oblique and vertical rectus movement were treated by horizontal rectus muscle transposition, both which corrected A-V patterns. Patients had good distance and near stereopsis postoperation. Binocular weakening oblique muscle surgery can correct primary ocular position, so surgical design of horizontal deviation about A-V patterns strabismus with abnormal oblique muscle was considered.
