Abstract

The introduction of the scleral type of contact lens electrode by Riggs in 1941 made it possible to record the electroretinogram (ERG) in human beings without apparent discomfort. As a result, literature on clinical ERG is steadily accumulating. However, with growing effort and experience, deficiencies in the contact lens electrode have become apparent and improved electrodes based on Riggs' model appeared. Despite these improvements, certain basic deficiencies of the contact lens electrode have not been eliminated.

This paper introduces a new electrode for the recording of the ERG. It is a gold ring and represents an entirely new approach. It eliminates deficiencies of the scleral type of contact lens electrode which are listed below:

1. The scleral type of contact lens electrode is made of glass or plastic material and has a fixed size. Consequently, it does not fit the different sizes and shapes of the eyes.

2. It is
