目的探讨不同术式的下斜肌减弱术在先天性垂直性麻痹性斜视中的疗效。方法对108例先天性垂直性麻痹性斜视分别行下斜肌断腱术、下斜肌截腱术、下斜肌转位术及下斜肌截腱联合同侧上直肌或对侧下直肌后徙术。结果治愈率81.5%,好转率10.2%,欠矫率5.6%,过矫率2.8%。90例头位改善或消失。32例恢复了I级视功能,9例恢复II级视功能,6例恢复了III视功能。结论下斜肌减弱术是治疗先天性垂直性麻痹性斜视的首选术式,它能有效地改善患者的外观及双眼单视功能。
Objective To investigate the efficacy of different surgical procedures for inferior oblique muscle weakening in congenital vertical paralytic strabismus. Methods 108 patients with congenital vertical paralytic strabismus under the oblique tendon surgery, lower oblique muscle surgery, inferior oblique muscle transposition and inferior oblique muscle tendon combined with the ipsilateral superior rectus or contralateral straight Muscle resettlement. Results The cure rate was 81.5%, improvement rate was 10.2%, undercorrection rate was 5.6% and overcorrection rate was 2.8%. 90 cases of head position to improve or disappear. 32 cases recovered class I visual function, 9 cases recovered class II visual function, and 6 cases recovered III visual function. Conclusions Lower oblique muscle weakening is the first choice for the treatment of congenital vertical paralytic strabismus. It can effectively improve the appearance of patients and binocular single vision function.
