Guidelines for clinical electroretinography in the dog: 2012 update

Area of Science:

• Veterinary Ophthalmology
• Canine Retinal Function Testing

Background:

• The full-field, flash electroretinogram (ERG) is a crucial test for evaluating canine retinal function.
• It aids in diagnosing hereditary retinal dystrophies, retinal degeneration, and other vision impairments in dogs.
• ERG is also utilized in ophthalmological research and for screening drug toxicity.

Purpose of the Study:

• To provide an updated set of guidelines for performing and interpreting clinical electroretinograms (ERGs) in dogs.
• To supersede the initial guidelines established in 2002 by the European College of Veterinary Ophthalmologists.

Main Methods:

• Review and synthesis of current practices and scientific literature related to canine ERG.
• Consideration of advancements in technology and understanding of retinal physiology in canines.
• Expert consensus among veterinary ophthalmologists to refine existing protocols.

Main Results:

• The updated guidelines offer standardized procedures for clinical ERG testing in dogs.
• Recommendations cover patient preparation, stimulus parameters, recording techniques, and interpretation criteria.
• The document addresses specific considerations for various canine breeds and ophthalmological conditions.

Conclusions:

• These revised guidelines will enhance the consistency and accuracy of canine retinal function assessment.
• They aim to improve the clinical diagnosis and management of retinal diseases in veterinary medicine.
• The updated guidelines serve as a vital resource for veterinary ophthalmologists and researchers.
