Ron Ofri was a member of the charter class of the Koret School of Veterinary Medicine, Hebrew University of Jerusalem, Israel. Upon his graduation in 1989 he traveled to the University of Florida, where he spent the next 4 years undergoing clinical training in veterinary ophthalmology and obtaining his Ph.D. During this time Ron developed an interest in the physiology of vision, focusing on retinal electrophysiology and changes in visual function resulting from glaucoma. Upon his graduation Ron returned to Israel and joined the faculty of his alma mater, where he is currently an Associate Professor in Veterinary Ophthalmology and winner of numerous Teacher of the Year awards. Ron is also a very popular international speaker, having been invited to talk in more than 15 countries, both in continuing education national and world congresses for general practitioners, as well as in advanced courses for veterinary ophthalmologists, including lectureship at the Basic Science Course of the American College of Veterinary Ophthalmology and numerous other forums. He has published more than 50 refereed papers, is a contibuting author to the last 2 editions of Veterinary Ophthalmology (KN Gelatt, ed.) as well as a co-author of the the popular textbook Slatter's Fundamentals of Veterinary Ophthalomology. Ron is a Diplomate of the European College of Veterinary Ophthalmology (ECVO), an ECVO Executive Board member and in 2002-2005 he served as President of the European Society of Veterinary Ophthalmology.

The anatomical and physiological basis of the ERG
This lecture will provide a brief review of retinal anatomy, focusing on the contributions of the various retinal cells and layers to the individual components of the ERG wave. We shall also discuss the physiological differences between rods and cones, and how these can be used to for electrophysiological differentiation between these two photoreceptor populations.

Coping with noise and technical problems in your ERG recordings
We shall discuss the effects of filtering and averaging on your ERG recordings. These can be helpful tools that will reduce the electrical noise which is contaminating your signals, but you should be aware of their potential dangers and" side-effects". Additional solutions and tips for coping with noise will be reviewed.
