Periods of epileptic nystagmus consisting of rightward eye deviation and right-beating nystagmus, alternating with upward eye deviation and upbeating nystagmus, occurred in a comatose patient with a left hemisphere subdural hematoma and seizures. The periods of upbeating nystagmus were associated with symmetric, low-voltage 3 to 4 Hz bifrontal spikes. Rightward eye deviation and right-beating nystagmus occurred with diffuse, predominantly left hemispheric 4 to 6 Hz sharp waves. No eye movements occurred in the absence of spike and wave activity. These correlations agree with current concepts of the cortical control of saccadic eye movements in monkeys studied by electrical stimulation.
一名患有左侧半球硬膜下血肿并伴有癫痫发作的昏迷患者出现了癫痫性眼球震颤，表现为右眼偏斜和向右摆动性眼球震颤，与向上眼偏斜和向上摆动性眼球震颤交替出现。向上摆动性眼球震颤发作期与对称的、低电压的3至4Hz双额棘波相关。右眼偏斜和向右摆动性眼球震颤与弥漫性、主要为左侧半球的4至6Hz尖波同时出现。在没有棘波和慢波活动时不出现眼球运动。这些相关性与通过电刺激研究的猴子中扫视性眼球运动的皮质控制的当前概念相符。
