Guest Editorial: The IPS and ISCEV joint Guidelines for full-field stimulus testing

<p dir="ltr">The first electrophysiology standard was published in 19891 as a collaboration between the International Society for Clinical Electrophysiology of Vision (ISCEV) and the National Retinitis Pigmentosa Foundation of the USA and is currently in its seventh version.2 These Standards are the keystone of clinical visual electrophysiology, embedding comparability and repeatability in the tests to an extent rarely achieved in clinical or laboratory measurement. We start 2024 with the publication of the Guideline for the Full-field Stimulus Test (FST).3 The Guideline is the result of a successful collaboration between ISCEV and the Imaging and Perimetry Society (IPS), bringing together both electrophysiology and psychophysics expertise as required for conduct and interpretation of the FST.</p>
