The process of determining acuities from visual evoked responses (VER's) was computer modeled. Based on amplitude variability data from earlier studies, the reliability and validity of the acuity determinations for normal subjects were assessed. For subjects who had poor quality VER data [low signal-to-noise (S/N) ratios], considerable variability and an artifactual shift toward elevated (better) acuity determinations were found.
通过计算机模拟了从视觉诱发电位（VER）确定视敏度的过程。基于早期研究的振幅变异性数据，评估了正常受试者视敏度测定的可靠性和有效性。对于VER数据质量较差[低信噪比（S/N）]的受试者，发现存在相当大的变异性以及向提高（更好）视敏度测定的人为偏移。
