Periodic alternating nystagmus 1) may be related to vestibulocerebellar system disease, 2) may occur with loss of vision, and 3) may be congenital in origin. We report the case of a patient with acquired periodic alternating nystagmus in whom the nystagmus followed bilateral vitreous hemorrhages. Upbeating nystagmus was interposed between the right beating and left beating phases. Bilateral vitrectomy resulted in the prompt disappearance of the nystagmus. The importance of visual function in relation to periodic alternating nystagmus and associated motility disturbances is emphasized.
周期性交替性眼球震颤1)可能与前庭小脑系统疾病有关,2)可能在视力丧失时出现,3)可能起源于先天性。我们报告一例获得性周期性交替性眼球震颤患者,其眼球震颤继发于双侧玻璃体积血。在右眼跳动和左眼跳动阶段之间插入了向上跳动性眼球震颤。双侧玻璃体切除术后眼球震颤迅速消失。强调了视觉功能与周期性交替性眼球震颤及相关运动障碍的关系。
