• We developed a corneal wick electrode that is free of photovoltaic artifact when used with a bright flash strobe and is convenient for routine clinical application. The corneal wick electrode is employed for bright flash electroretinogram (ERG) recordings and for research measurements of the early receptor potential. The wick electrode gives accurate, stable, reproducible recordings with an amplitude comparable to that obtained with standard contact lens electrodes.
