Comparative ocular pathology; comparative dental pathology; The primary thrust of Dr. Dubielzig's research is to characterize the morphological changes seen in spontaneous animal disease, with a particular emphasis on ocular and dental problems. Dr. Dubielzig receives specimens of spontaneous ocular and dental disease from around the world. By working closely with the veterinary clinical specialists, it is hoped that more can be learned about the biological behavior of animal diseases. Current research projects include characterization of ocular sarcomas in cats that occur in traumatized eyes, characterization of the proliferative response following severe ocular trauma in dogs and cats, classification of ocular and dental neoplasms, and the morphological changes seen in spontaneous glaucoma

General and systemic pathology;

Richard R. Dubielzig DVM Professor of Pathology, School of Veterinary Medicine Director, Comparative Ocular Pathology Laboratory of Wisconsin Dr Dubielzig received his Veterinary degree from the university of Minnesota in 1972 and completed his residency training in anatomic pathology at the University of Pennsylvania in 1977. Dr Dubielzig became a Diplomate of the American College of Veterinary Pathology in 1977. He returned to Madison, his hometown, to join the new Veterinary School as the charter faculty member in the Department of Pathobiological Sciences in 1983. Dr Dubielzig has made ocular pathology an area of special interest and has run a mail in pathology service for veterinary ophthalmologists, which currently receives approximately 3000 specimens per year. Dr Dubielzig is an author on 180 research papers and 230 published abstracts with an emphasis on ocular pathology. His areas of particular interest are ocular neoplasia, glaucoma in dogs and cats, ocular trauma, and inflammatory disease.
