The pattern electroretinogram (PERG) is a retinal response evoked by viewing a temporally alternating pattern, usually a black and white checkerboard or grating. The PERG is important in clinical and research applications because it provides information both about retinal ganglion cell function and, because the stimulus is customarily viewed with central fixation, the function of the macula. The PERG can therefore facilitate interpretation of an abnormal pattern VEP by revealing the retinal responses to a similar stimulus to that used for the VEP. However, practitioners may have difficulty choosing between the different techniques for recording the PERG that have been described in the literature. The International Society for Clinical Electrophysiology of Vision published a standard for clinical PERG recording in 2000 to assist practitioners in obtaining good quality reliable responses and to facilitate inter-laboratory communication and comparison. This document is the scheduled revision of that standard.
图形视网膜电图（PERG）是通过观察时间上交替出现的图形（通常是黑白棋盘格或光栅）诱发的视网膜反应。PERG在临床和研究应用中很重要，因为它既提供有关视网膜神经节细胞功能的信息，又由于通常是通过中心注视观察刺激，所以还能提供黄斑功能的信息。因此，PERG通过揭示视网膜对与用于视觉诱发电位（VEP）相似刺激的反应，有助于解释异常的图形VEP。然而，从业者在选择文献中描述的不同PERG记录技术时可能会遇到困难。国际视觉临床电生理学会于2000年发布了临床PERG记录标准，以帮助从业者获得高质量可靠的反应，并促进实验室间的交流和比较。本文档是该标准的定期修订版。
