Three groups of animals were studied during the four-hour period following their recovery from total occlusion of retinal circulation for periods of 30, 60 and 90 minutes. During incremental increases of ischemia, recovery followed a pattern that is the reverse of that previously reported, inasmuch as wave amplitude is concerned. From total extinction, ERGs recovered and showed hyperresponses. Delays, however, behaved differently: they increased with recovery time--the opposite of what was expected. All signs were inversely proportional to the duration of ischemia. Sixty minutes of occlusion appears to be a threshold beyond which ERGs do not recover as well.
在视网膜循环完全阻塞30、60和90分钟后恢复的四小时期间，对三组动物进行了研究。在缺血逐渐增加的过程中，就波幅而言，恢复情况与先前报道的模式相反。从完全消失开始，视网膜电图恢复并显示出超反应。然而，延迟的表现有所不同：它们随着恢复时间的增加而增加——这与预期相反。所有指标都与缺血持续时间成反比。60分钟的阻塞似乎是一个阈值，超过这个阈值，视网膜电图就不能很好地恢复。
