In this course you will learn everything you wanted to know about ERG but were afraid to ask. We shall begin by reviewing the anatomy and physiology of the retina, to understand the origin of the ERG signal. Then we shall review the technical setup for a proper recording – how to prepare your patient, the equipment needed, and the protocols and settings you will use. We shall discuss how to improve your recordings by overcoming technical issues, such as noise, that may affect your recording. Additional electrophysiological modalities, such as VEP’s, and pattern and multifocal ERG, will also be reviewed. Next, we will discuss ancillary tests in screening of cataract patients (e.g., gonioscopy, ultrasound). We shall conclude by reviewing and discussing clinical cases in electroretinography. You are also encouraged to submit your own ERG cases for discussion! In the second part of the course, we will introduce you to the new RETevet handheld ERG unit and its operation. We will conduct a wetlab, enabling you to practice recordings of various ERG protocols on sedated dogs. As space in the wetlab is limited, the class will be divided into two groups, and those not in the wetlab will „explore the posterior segment“ with Barbara Braus.

The course is intended primarily for two audiences. The first is veterinary ophthalmologists and other veterinarians with a substantial ophthalmology caseload. The second is researchers in the fields of vision and ophthalmology who conduct electrophysiological recordings in the course of their work.

• Understand the anatomical and physiological origins of the ERG signal
• Be able to conduct a high-quality ERG recording, having covered every step from patient preparation to selecting the equipment and protocols suited for your needs
• Overcome technical issues affecting your signals, analyze the recording and reach a diagnosis
