The ISCEV Standard for Full-Field Clinical Electroretinography (ffERG) provides updated guidelines for recording ERGs. It defines six standard ERG protocols based on eye adaptation and flash strength: dark-adapted 0.01 ERG (rod response), dark-adapted 3 ERG (rod-cone response), dark-adapted 10 ERG (strong flash), dark-adapted oscillatory potentials, light-adapted 3 ERG (cone response), and light-adapted 30 Hz flicker ERG. The standard specifies stimulus parameters, including flash strength, duration, and wavelength, to ensure consistency and reproducibility across laboratories. It also includes guidelines for electrode use, stimulus calibration, and recording equipment. The standard encourages the use of additional ERG protocols beyond the minimum requirements. It emphasizes the importance of accurate calibration, proper patient preparation, and standardized reporting of ERG results. The standard acknowledges the use of LED and xenon lamps as light sources and specifies CIE coordinates for stimuli. It also addresses the importance of reference values, age adjustments, and pediatric ERG recording. The standard aims to ensure that ERG results are comparable globally and that they provide reliable diagnostic information for clinical and research purposes.The ISCEV Standard for Full-Field Clinical Electroretinography (ffERG) provides updated guidelines for recording ERGs.
