Residents' Workshop

Friday, September 28th, 2018 | 2:30pm-5:00pm - Nicollet A-C, 1st Floor

This lecture series will educate ACVO residents on the current status and recent advancements in diagnosis and treatment of eye diseases in horses.  Noted experts in the field will review advanced diagnostic techniques, recognition and treatment of infectious and non-infectious (immune-mediated) diseases of the equine eye, and advances in ophthalmic surgical techniques of horses. 

The Residents’ Workshop is open to all attendees at the conference. ACVO Members are encouraged to attend the ACVO Annual Meeting of the Voting Members which occurs at the same time. This session will be recorded for all members to view post-conference for free if they wish.

30 minute lectures with a short question and answer session following each speaker.

Moderator:  Dr. Brian Gilger

2:30 PM - Dr. Eric Ledbetter, Cornell

“Advanced diagnostic techniques of the equine eye”

Ophthalmic imaging techniques available for use in equine medicine have rapidly expanded in recent years. We will discuss the indications and techniques for advanced ophthalmic diagnostic imaging of the horse, including in vivo confocal microscopy, ocular coherence tomography, and specular microscopy.

About Dr. Ledbetter

Dr. Eric Ledbetter is a diplomate of the American College of Veterinary Ophthalmologists and an Associate Professor of Ophthalmology at the Cornell University College of Veterinary Medicine. After graduating from the University of Missouri College of Veterinary Medicine, he completed a small animal medicine and surgery internship at Texas A&M University College of Veterinary Medicine and a comparative ophthalmology residency at Cornell University, where he joined the faculty in 2006.

Dr. Ledbetter’s research interests include in vivo ocular imaging techniques, ocular infectious disease, and corneal disease. In addition to research and teaching endeavors, Dr. Ledbetter provides clinical ophthalmology services within Cornell University’s Companion Animal and Equine & Farm Animal Hospitals.

3:05 PM - Dr. Mary Lassaline, UC Davis

“Infectious disease and the equine eye”

This lecture will review infectious diseases of the horse that commonly affect the eye and the rest of the body.  For each infectious disease, clinical signs, diagnostic tests, therapeutic options, prognosis, and pathophysiology will be reviewed.  Bacterial, viral, mycotic, and parasitic diseases will be included.

About Dr. Lassaline

Dr. Lassaline earned her veterinary degree from Michigan State University,
completed a medicine and surgery internship at Rood & Riddle Equine Hospital in Lexington,
Kentucky, and completed a residency in veterinary ophthalmology at the University of
Florida. She has worked in private practice in veterinary ophthalmology and served on the
faculty at University of Pennsylvania prior to joining the faculty at University of California-
Davis, where she is currently Associate Professor of Clinical Equine Ophthamology. Her
research interests focus on equine corneal disease and graduate veterinary medical education.


3:40 PM - Dr. Brian Gilger, NC State

“Immune-mediated disease and the equine eye”

We will review common diseases of the horse eye that are presumed to be of immune-mediated or auto-immune cause.  The diagnosis and treatment of immune mediated keratitis, heterochromia iridokeratitis (HIK), and recurrent uveitis will be discussed.  

About Dr. Gilger

Dr. Brian Gilger received his veterinary degree from The Ohio State University in Columbus, Ohio.  After an ophthalmology residency and masters degree at Auburn University, Dr. Gilger returned to The Ohio State University as an Assistant Professor; then in October 1995, he joined the faculty at North Carolina State University where he is now a Professor and head of clinical ophthalmology.  Dr. Gilger has been president of the American College of Veterinary Ophthalmologists, a board member of the Ocular Toxicology Sub-specialty (OTSS) of the Society of Toxicology, and a member of the AAALAC Board of Trustees. Dr. Gilger has been a member of ARVO since 1989 and served on the ARVO Animals in Research Committee for 8 years, including serving as chair of this committee for 3 years. He is a Silver Fellow of ARVO (2016). He is the co-founder and current President of the International Equine Ophthalmology Consortium. He is board certified in Veterinary Ophthalmology and Toxicology. Dr. Gilger’s research is focused on sustained ocular drug delivery, ocular pharmacology, animal models of ocular inflammation, and ocular immunology. He is a consultant for many pharmaceutical companies and CROs, has authored over 150 peer-reviewed scientific manuscripts, has written over 30 book chapters, and is the editor of six books, including 3 editions of Equine Ophthalmology, the 2014 Springer publication Ocular Pharmacology and Toxicology and the 2018 Springer publication Standards for Ocular Toxicology and Inflammation.

4:15 PM -  Dr. Richard McMullen, Auburn

“Advanced surgical procedures of the equine eye”

We will review corneal lamellar keratoplasties, glaucoma valve (gonio shunt) and cyclosporine implant placement and discuss the necessary surgical modifications to perform these procedures under standing sedation.  We will also review the indications and surgical techniques of pars plana vitrectomy and phacoemulsification in the adult horse.

About Dr. McMullen

Dr. Richard McMullen graduated from Ludwig-Maximilians-University (LMU), Munich in 2002, and immediately joined LMU’s Clinic for Horses. Upon completion of his doctorate and advanced certification in equine ophthalmology in 2006 he moved to Raleigh, NC for a residency in comparative ophthalmology at North Carolina State University (NCSU). Following completion of his residency, Dr. McMullen remained on faculty at NCSU until 2012.  From January, 2013 to October 2016, Richard established and ran the equine ophthalmology service at the Equine Clinic Munich-Riem, Germany. In January, 2017 he once again returned to the U.S. to join the ophthalmology service at Auburn University where he is currently an Associate Professor of Equine Ophthalmology. Auburn University is now offering an Equine Ophthalmology rotation in addition to their Small Animal Ophthalmology rotation. Dr. McMullen serves on the ECVO Scientific Committee, and is a board member of the International Equine Ophthalmology Consortium (IEOC). His research interests are anchored in clinical equine ophthalmology and vision, ophthalmic photography, advanced diagnostic imaging, and standing ophthalmic surgery in horses.
