A new electrode for electroretinography (ERG) has been produced. The new device made of gold filament was applied as corneal and noncorneal electrod. Flash ERG and pattern ERG were recorded in normal subjects using this new electrode and compared with those made by available electrodes. There were so significant differences in amplitude and latency between the new electrode placed on the cornea and the JET-type electrode. For pattern ERG there were no significant differences between the new electrode placed in the lower fornix and a gold-foil-type electrode. As this new electrode is less expensive and more comfortable than the available electrodes, it is clinically useful.
