存在两个反方向中间带的先天性冲动性眼球震颤的治疗研究

目的 探讨治疗存在两个反方向中间带的先天性冲动性眼球震颤的有效方法。方法 对14例存在两个反方向中间带的先天性冲动性眼球震颤患者，采用三棱镜中和两侧代偿头位扭转角的方法确定两个中间带中起主导作用的中间带后，配戴三棱镜；对代偿头位改善且不转向对侧者；设计并实施中间带移位手术。结果 采用此方法治疗的14例患者中，1次手术成功者10例，2次手术成功者2例，1次手术后配戴三棱镜症状缓解者2例；全部患者正前方注视视力均提高。结论 手术前确定两个中间带中起主导作用的中间带；配戴三棱镜后确定代偿头位改善且不转向对侧，是行中间带移位手术治疗存在两个反方向中间带的先天性冲动性眼球震颤成功的关键。该方法疗效可靠、可供临床推广使用。

Treatment of congenotal jerky nystagmus with opposite bidirectional neutral zone

Objective To explore a method for the treatment of congenital jerky nystagmus with opposite bidirectional neutral zones. Method The relatively used side between the two neutral zone was found by neutralizing bilateral head torsion angle with prisms. The surgical intervention was indicated for those patients whose head position would not turn to another side. Result There were 14 cases treated by this method, none of these cases whose head position turned to another side. Ten cases underwent once operation, 2 cases, twice operations and another 2 cases undertook once operation with additional prism correction. The compensatory head posture was corrected and the vision in the primary position of gaze was improved in all the cases. Conclusion This therapy for congenital jerky nystagmus with opposite bidirectional neutral zone shows significant therapeutic effects and can be available for clinical application.
