Area of Science:

Veterinary Ophthalmology
Clinical Electrophysiology

Background:

Electroretinography (ERG) is crucial for assessing retinal function in animals.
Standardized ERG protocols, like those from the International Society for Clinical Electrophysiology of Vision (ISCEV), ensure reliable data.
Evaluating new, cost-effective diagnostic tools is important for veterinary clinical practice.

Purpose of the Study:

To compare the performance of a novel fiber electrode prototype against a standard ERG-Jet electrode for veterinary ERG recordings in dogs.
To determine if the fiber electrode prototype yields comparable results in terms of magnitude and waveform quality for various ERG responses.

Main Methods:

Ten healthy Yorkshire terrier dogs were enrolled in the study.
Dark- and light-adapted ERG responses were recorded using both the ERG-Jet electrode and the fiber electrode prototype.
Examinations were conducted over two separate visits to ensure comparability, with electrode types and eye recording order randomized.

Main Results:

Both the ERG-Jet and fiber electrode prototype produced similar magnitudes and waveform qualities across all tested ERG responses.
No significant differences were observed in ERG amplitudes and implicit times between the two electrode types for rod, maximal rod-cone summed, cone, and 30-Hz flicker responses.

Conclusions:

The fiber electrode prototype is a reliable and effective alternative for clinical veterinary ERG recordings.
This low-cost device can be utilized for accurate assessment of retinal function in dogs, offering a practical option for veterinary diagnostics.
