Research Interests

Dr. Sandmeyer has research interest in a variety of topics in veterinary ophthalmology. A primary focus has been congenital stationary night blindness (CSNB) and equine recurrent uveitis (ERU) in the Appaloosa, Knabstrupper and Pony of the America horse breeds. Other interests include hereditary and acquired ocular diseases in the dog, infectious conjunctivitis in cats, and ocular pathology.  Current research interests include the use of optical coherence tomography in the diagnosis of retinal disease in veterinary species.
