A patient is presented who has had three six-month episodes of oscillopsia over the last eight years. During the episodes, abnormal smooth pursuit and optokinetic nystagmus were noted, but there were no other abnormalities. Oculography during the most recent episode demonstrated that when tracking from right to left, the patient's smooth pursuit was reversed. There are several features of the case which suggest that the aetiology may be a form of congenital nystagmus. A possible alternative mechanism whereby such an abnormality might arise as an acquired lesion is discussed.
本文报告了一名患者，在过去八年中曾三次出现为期六个月的视振荡发作。发作期间，观察到异常的平稳跟踪和视动性眼球震颤，但无其他异常。最近一次发作期间的眼动描记术显示，当从右向左跟踪时，患者的平稳跟踪是反向的。该病例的几个特征表明病因可能是一种先天性眼球震颤。文中讨论了这种异常可能作为后天性病变出现的一种可能的替代机制。
