双眼上斜肌延长术对A型斜视的影响

目的 探讨双眼上斜肌肌腱延长手术对A型斜视的影响.方法 对11例双眼上斜肌功能亢进伴A型斜视患者施行上斜肌肌腱延长术,对术前术后的眼位、A征的矫正情况、双眼视功能等进行分析.结果 11例中,术前A征10～34,平均(19.27±7.50)△,术后上方与下方水平斜视度差-12～3△,平均差别(3.67±3.28)△,术前与术后比较差异有统计学意义(P＜0.001);手术对A征的矫正量15～38△平均(20.64±4.97)△;术后A-V征均消失;6例患者恢复双眼视觉,2例存在立体视觉.结论 上斜肌延长手术治疗伴上斜肌亢进的A型斜视安全有效;特别对于轻中度上斜肌亢进、A型斜视和具有双眼视功能患者,针对性较好,不易出现并发症.

The influence of bilateral superior oblique tendon-expander procedures for A-pattern strabismus

Objective To evaluate the efficacy of bilateral SO tendon-expander for the patients with A- pattern strabismus. Methods 11 patients were treated with the SO tendon-expander surgery. Pre-and post-operative eye positions,A-Pattern Strabismus and binocular visual function were analyzed .Results 11 cases ,per-operative A-Pattern average 19.27 △±7.50 △; The difference in horizontal strabismus between up and downgaze average 3.67 △±3.28 △; A- pattern strabismus improved average 20.64 △±4.97 △, There were significant differences(P＜0.001 ) ;no patient had A-V pattern strabismus postoperatively, 6 patients had binocular visual function, 2 patients had stereopsis .Conclusions SO tendon-expander surgery are effective approach for the patients with the SO overaction and A-pattern strabismus; SO tendon-expander surgery is better for the treatment of mild to-moderate superior oblique overaction, A- pattern strabismus and the patients with binocular visual function.
