ABSTRACT
The full-field electroretinogram (ERG) records the summed transient electrical responses from the entire retina elicited by a flash stimulus delivered in a full-field dome Fig. 1.1. The ERG was discovered in excised animal eyes in the middle 1800s, and ERG recording in humans was first reported in 1920s. The clinical use of full-field ERG began in the 1940s, and in 1989, standard for clinical full-field ERG was established by the International Society for Clinical Electrophysiology of Vision ISCEV (1). The ERG standard is reviewed every three years, and the most updated version is available on the ISCEV Internet site. No major revision of the standard has occurred over the years, and the standard is summarized in Table 1.1. This chapter discusses ERG assuming an understanding of basic retinal anatomy and physiology detailed at the end of the chapter.
