Abstract
The pattern electroretinogram (PERG) is a retinal response evoked by a contrast-reversing pattern, usually a black and white checkerboard, which provides information about macular and retinal ganglion cell function. This document from the International Society for Clinical Electrophysiology of Vision (
www.iscev.org) is a scheduled revision of the ISCEV PERG Standard, which updates and replaces the 2007 update and all earlier versions. The standard defines a single minimum stimulus and recording protocol for clinical PERG testing to assist practitioners in obtaining good quality responses and to facilitate inter-laboratory comparison. The present revision tightens stimulus specifications, expands on steady-state PERG recording, addresses visual stimulus display distinctions (CRT vs. LCD), and provides a more explicit definition of response components.
