目的　为探讨不规则先天性眼球震颤手术的疗效。方法　采用四条水平肌肌延伸术对 38例不规则先天性眼球震颤进行手术治疗。结果　 38例不规则先天性眼球震颤肌延伸术后正前方眼震值平均减低 3.5mm,正前方平视残留 0 .5～ 1 mm眼震值。术后随访半年 ,无明显回退。结论　采用肌延伸术治疗不规则先天性眼球震颤 ,可明显减低正前方眼震值 ,术后疗效满意 Objective To investigate the effect of irregular congenital nystagmus surgery. Methods Thirty-eight patients with irregular congenital nystagmus were treated with four horizontal muscle myosin extensions. Results 38 cases of irregular congenital trehalose muscle extension anterior nystagmus an average reduction of 3.5mm, in front of flat mimic residual 0.5 ~ 1 mm nystagmus value. Follow-up for six months, no significant regression. Conclusion Muscle extension treatment of irregular congenital nystagmus, can significantly reduce the value of anterior nystagmus, postoperative satisfaction
