ISCEV Standards, Guidelines and Extended Protocols

This topical collection brings together current Standards, Guidelines and Extended protocols published in Documenta Ophthalmologica by the International Society for Clinical Electrophysiology of Vision (ISCEV). The ISCEV Standards define minimum protocols for stimulation, recording and reporting, to enable acceptable and consistent evaluation and to allow recognition and comparison of test results among laboratories worldwide. The Standards facilitate reliable comparisons of serial and high quality legacy data for clinical monitoring and for research purposes. When standards cannot be met the reason should be documented in the report. There are currently ISCEV Standard protocols for five tests: full-field electroretinography (ERG), pattern ERG, multifocal ERG, electro-oculography (EOG) and for visual evoked potentials (VEPs). There are two ISCEV guidelines currently, that describe clinical practice and apply across the Standards and extended protocols. The ISCEV guide to Electrodiagnostic Procedures gives an overview of the main clinical visual electrophysiology tests and typical applications for diagnosis and clinical management, with examples. The ISCEV guidelines for calibration, and verification of stimuli and recording instruments supports the set up and maintenance of laboratories and equipment for clinical electrophysiology testing. ISCEV encourages the use of additional electrophysiological test procedures, either customised or following ISCEV extended protocols, particularly if an aid to diagnosis, but these are not an alternative to ISCEV standard testing unless for specific research purposes. The ISCEV extended protocols are evidence-based, and are intended to encourage convergence of methods, but are less prescriptive than Standards.
