20.500.12556/DiRROS-27776 ISCEV standard for clinical visual evoked potentials (2025 update) Visual evoked potentials (VEPs) are electrophysiologic responses to pattern or flash stimuli, recorded over the occiput. VEPs can provide information regarding the function of the visual system and are valuable in the diagnosis and investigation of optic nerve disease or post-retinal visual pathway dysfunction. The ISCEV VEP Standard specifies stimulus and recording conditions for three basic types of recording: (1) Pattern-reversal VEPs elicited by checkerboard stimuli with large 1° (degree) and small 0.25° check widths. (2) Pattern onset/offset VEPs elicited by checkerboard stimuli with large 1° and small 0.25° check widths. (3) Flash VEPs elicited by a flash which subtends a visual field of at least 20°. The ISCEV VEP Standard protocols are defined for a single recording channel with a midline occipital active electrode. Multi-channel VEPs for evaluation of chiasmal and post-chiasmal lesions, together with protocols specific for pediatric populations, are also described in this document as non-standardized additions. The main changes in the updated ISCEV Standard for clinical VEP include an option to perform a simultaneous pattern electroretinogram (PERG) and pattern-reversal VEP recording, a revised definition of the origin and the analysis of the most prominent VEP components, and more precise descriptions of non-standard multi-channel and pediatric VEP recordings, intended to encourage convergence of widely used non-standard methods. These changes aim to provide a clinically relevant document about current practice which will facilitate good quality recordings and inter-laboratory comparisons. clinical standards visual evoked potential International Society for Clinical Electrophysiology of Vision pattern reversal visual evoked potential pattern onset/offset visual evoked potential flash visual evoked potential true false true Angleški jezik Ni določen Neznano 2026-02-24 14:19:51 2026-02-24 14:19:52 2026-02-25 03:50:49 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 20. 10. 2025; str. 97–112 Vol. 151 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 617.7 1573-2622 10.1007/s10633-025-10042-1 253857027 RAZ_Sustar_Habjan_Maja_2025.pdf RAZ_Sustar_Habjan_Maja_2025.pdf 1 AE285EADDA345C2CD105D422AFBCF5E3 e951927826a1dc0d89fbfc3d8092b512745e23f2b8763a1f77d57ed74db9e8a8 b5467205-1183-11f1-9cb0-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=40830 https://doi.org/10.1007/s10633-025-10042-1 0 c6edf091-1183-11f1-9cb0-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=40831 Univerzitetni klinični center Ljubljana 0 0 0
