On Tuesday, Sept. 8, at 6:30 p.m., large animal ophthalmologist Catherine Nunnery, DVM, will discuss many aspects of the equine eye and vision in her talk, “Equine Vision: What Does My Horse See?”

The presentation is part of the First Tuesday Lecture Series at the University of Pennsylvania School of Veterinary Medicine (Penn Vet) New Bolton Center and will take place at 382 West Street Road, in Kennett Square.

Nunnery’s lecture will include the basic anatomy and physiology of vision and then explore more specific details of what the horse sees. Equine visual acuity, field of view, color vision, day vision, night vision, and visual adaptions will be explained. She will also describe vision testing and how veterinarians determine if a horse needs glasses. She will present information on ocular diseases that affect vision, with images of how vision is diminished.

Nunnery leads the experts in New Bolton Center’s Ophthalmology Service in providing complete ocular examinations, diagnostics, and treatment, and performing surgeries for lid lacerations, deep corneal ulcers or perforations, periocular tumors, and cataracts
