目的 探讨Helveston综合征的临床特点和手术方法.方法 回顾分析Helveston综合征患者29例,分析其临床特点、手术方法及术后眼位及双眼视功能情况.结果 29例病例术后正位28例(96.6％),A征消失26例(89.7％),A征由术前的14.24△±5.13△减少为5.21△±4.32△;术后原在位垂直斜视度由术前的11.87△±5.37△减少为5.11△±1.78△;手术前后的外斜视、A征及DVD的斜视度均有显著性差异,P<0.05.术后8例恢复双眼视觉,3例恢复立体视功能.结论 Helveston综合征一次手术同时矫正外斜A征、上斜肌功能过强和DVD效果良好.“,”Objective To investigate the characteristics and surgical methods of Helveston syndrome.Methods 29 cases of Helveston syndrome were studied.Post-operative eye positions, A-pattern,DVD,function of superior oblique and binocular visual function were examined and analyzed.Results For 29 cases, post-operative orthotorpi were 28 cases (96.6％).A-pattern were corrected in 26 cases(89.7％) and A-pattern from 14.24△±5.13△ reduced to 5.21△±4.32△.Post-operative vertical deviation in primary position average from 11.87△±5.37△reduced to 5.11△±1.78△. There were significant differences,P<0.05.8 cases have binocular vision and 3 cases stereopsis post-operative.Conclusions Correcting Helveston syndrome include A-pattern, superior oblique over function and DVD achieved good effect by one surgery.
