To examine the reliability of VER data, responses were obtained from 9 normal subjects. For steady state and transient displays, 7 consecutive VERs were obtained using 10, 25, 50, 75 and 100 ensemble averaged 384 ms activity samples each. Data from the 7 VERs were averaged by considering the first 3, the first 5, and all 7 VERs. For each display, maximum reliability was obtained by averaging at least 5 VERs with each consisting of 50 or more ensemble averaged samples. The steady state display produced more reliable data than did the transient display, but when each display system was used in a refraction format, the transient display produced refractions with narrower uncertainty ranges.
为了检验视觉诱发电位（VER）数据的可靠性，我们从9名正常受试者那里获取了反应。对于稳态和瞬态显示，使用10、25、50、75和100个每组均为384毫秒活动样本的集合平均，连续获取7个VER。通过考虑前3个、前5个以及所有7个VER，对这7个VER的数据进行平均。对于每种显示，通过平均至少5个VER（每个VER由50个或更多集合平均样本组成）可获得最大可靠性。稳态显示产生的数据比瞬态显示更可靠，但当每个显示系统以验光形式使用时，瞬态显示产生的验光不确定性范围更窄。
