Duration, reliability, and sensitivity of kinetic thresholds were evaluated for the I/4e, I/2e, and I/1e Goldmann-equivalent targets as a function of stimulus velocity (1 degrees to 8 degrees/s) using the SQUID automated perimeter. For all targets, the average duration of kinetic meridional scans decreased significantly as stimulus velocity increased from 1 degrees to 4 degrees/s. Minimal reductions in kinetic scan times were present for stimulus velocities above 4 degrees/s. All targets appeared to have reductions in sensitivity at velocities above 4 degrees/s (target detection occurring at more central visual field locations) that were presumably related to the observers' reaction times. There were no consistent differences in the variability of kinetic thresholds for different stimulus velocities. When all factors were considered, a stimulus velocity of 4 degrees/s seemed to be optimal for kinetic scans of all targets in the central and peripheral visual field.
使用超导量子干涉装置自动视野计，评估了I/4e、I/2e和I/1e戈德曼等效视标在刺激速度（1度/秒至8度/秒）变化时的运动阈值的持续时间、可靠性和敏感性。对于所有视标，随着刺激速度从1度/秒增加到4度/秒，运动子午线扫描的平均持续时间显著缩短。刺激速度高于4度/秒时，运动扫描时间的减少最小。所有视标在速度高于4度/秒时似乎敏感性降低（目标检测出现在更中心的视野位置），这可能与观察者的反应时间有关。不同刺激速度下运动阈值的变异性没有一致的差异。综合考虑所有因素，4度/秒的刺激速度似乎是中央和周边视野中所有视标运动扫描的最佳速度。
