Infrared oculography was performed during sustained lateral gaze in 12 normal subjects to investigate end-point nystagmus while fixating a target light. Five failed to develop nystagmus despite deviation up to 40 degrees from 4 to 5 min. Six subjects developed nystagmus immediately or shortly after reaching the deviated position. In one, the nystagmus (0.5 degrees to 1 degree and 1.0 Hz) began with only a 20 degree deviation. In another subject, "fatigue" nystagmus developed after 1 min at 30 degrees, and at 35 degrees nystagmus began within 2 sec. One subject developed only fatigue nystagmus, which began after more than 4 min of sustained deviation. In all instances the slow phase had primarily a linear, rather than exponential, waveform.
对12名正常受试者在持续向外侧凝视期间进行红外眼震图检查，以研究注视目标光时的终末性眼震。尽管在4至5分钟内偏差达40度，但有5名受试者未出现眼震。6名受试者在达到偏斜位置后立即或不久后出现眼震。其中1名受试者，眼震（0.5度至1度，频率1.0赫兹）在仅20度偏差时就开始出现。另一名受试者，在30度时持续1分钟后出现“疲劳性”眼震，在35度时2秒内就开始出现眼震。1名受试者仅出现疲劳性眼震，在持续偏斜超过4分钟后开始出现。在所有情况下，慢相主要呈线性波形，而非指数波形。
