Summary This lecture will introduce the standard tests used in routine electrophysiological practice, namely full‐field, pattern and multifocal electroretinography, and electro‐oculography. Although the Course will concentrate on disorders of retinal function, the cortical visual evoked potential will also be briefly addressed. The origins of the signals will be discussed and common disorders used to illustrate the principles of clinical interpretation ie the separation of rod and cone system function; localisation of disease either to photoreceptors or inner retina; and the distinction between localised macular disease and generalised retinal dysfunction, always relating the nature of the electrophysiological abnormalities to the underlying pathophysiology.
