方法：回顾分析我院手术治疗且资料完整的15例30眼Helveston 综合征病例，根据患者上斜肌亢进及分离性垂直偏斜(dissociated vertical deviation，DVD)程度的不同选择不同的手术方式。

结果：患者8例16眼行双眼上斜肌鞘内断腱术，术后随访1～3a，A征均消失，其中3例6眼DVD消失， 5例10眼DVD减轻，均未再次行DVD矫正手术； 患者4例8眼行双眼上直肌后徙联合双眼外直肌后徙并垂直移位术，术后随访1～3a，眼位正位，A征消失，1例2眼DVD消失，3例6眼DVD减轻，未再行二次手术； 患者3例6眼行双眼水平直肌后徙联合垂直移位术，术后随访6mo，眼位正位，A征消失，DVD减轻，未再次行二次手术。

结论：Helveston 综合征可根据患者上斜肌亢进及DVD程度的不同选择不同的手术方式。

METHODS: Fifteen cases(30 eyes)with Helveston syndrome were studied. Surgical method was selected according to the degree of superior oblique muscle overaction and dissociated vertical deviation(DVD).

RESULTS: Binocular superior oblique intrathecal tenectomy was performed in 8 patients(16 eyes). Follow-up period after surgery was 1-3a. Those 8 patients got A-sign correction, of which 3 patients(6 eyes)got DVD vanished and 5 patients(10 eyes)got DVD alleviation. None of the 8 cases needed another operation for DVD. Binocular superior rectus recession and binocular lateral rectus recession with vertical offsets was performed in 4 patients(8 eyes). Follow-up period after surgery was 1-3a. The 4 patients got A sign correction and with orthophoria, of which 1 patient(2 eyes)got DVD vanished and 3 patients(6 eyes)got DVD alleviation. None of the 4 cases needed another operation for DVD. Binocular lateral rectus recession and vertical offsets was performed in 3 patients(6 eyes). Follow-up period after surgery was half a year, with orthophoria, no A sign, DVD weakened, and no second operation was needed.

CONCLUSION: Surgical procedures for Helveston syndrome can be selected according to the degree of superior oblique muscle overaction and DVD.
