Electroretinography With the RM Electrode: Normative Reference Ranges, Variation With Age, and Comparison With the Burian-Allen Electrode.

ABSTRACT:

Purpose

The RM Electrode is a new, single-use, soft-contact lens electrode for recording the full-field electroretinogram (ffERG). Aims were (1) to define the ffERG reference ranges for the RM Electrode, with age, from healthy volunteers and (2) to compare ffERGs recorded with the RM Electrode and Burian-Allen (BA) electrode.

Methods

The ffERGs were recorded using the International Society of Clinical Electrophysiology of Vision (ISCEV) standard, including four ISCEV extended protocols: dark-adapted red flash, photopic negative response, ON-OFF, and S-cones. Electroretinogram (ERG) parameters and recording stability, measured from the percent coefficient of variation (%CV), were compared across electrodes.

Results

Participants were 40 (19 female) healthy volunteers ag
