Abstract

The corneal contact lens electrode, because of its convenience, has replaced the cotton-wick electrode for recording electroretinograms from patients and animals such as dogs, rabbits, and cats. The cotton-wick electrode, however, remains popular for rat electroretinogram measurements because small contact lens corneal electrodes that fit rat eyes are difficult to fabricate. We prepared corneal electrodes from disposable needles for use in recording electroretinograms from rats. The electrodes were readily prepared, were inexpensive, and were used successfully in six rats.
