Erratum

There is an error in Table 1 of the recently published ISCEV Standard for full-field clinical electroretinography (2015 update) [1]. Users of this standard should note that the filter settings for dark-adapted oscillatory potentials (OPs), as correctly specified in the text, require that the high-pass filter should remove frequencies of 75 Hz and below from the ERG waveform; the low-pass filter setting of 300 Hz or above is the same as for other ERG tests. Table 1 is provided below with the correct bandpass for OPs.

a‘Dark-adapted’ ERGs are recorded ERGs without further dark adaptation. Thus only the weak flash ERG is a fully dark-adapted response

bFilters should remove frequencies below 75 Hz. Filtering somewhat higher frequencies is acceptable but Standard OPs must include frequencies between 100 and 300 Hz
