A Dogster reader wrote in to tell us about their dog who suddenly went blind. As it turned out, she had something called sudden acquired retinal degeneration syndrome. Not much is known about this mysterious eye disease, but veterinarian Freya Mowat, an assistant professor of ophthalmology at North Carolina State University’s College of Veterinary Medicine, wants to find out what causes SARDS so it can be better treated and hopefully even prevented someday.

Dr. Mowat is one of the principal investigators of a clinical trial searching for answers about SARDS. Dogs diagnosed with SARDS are typically middle-aged and usually female, with no history of vision problems. For unknown reasons, the rods and cones in the eyes become damaged, leading to retinal degeneration and ultimately, total permanent blindness. In addition to blindness, dogs with SARDS frequently have an increased appetite and weight gain, as well as increased thirst and urination, reminiscent of dogs with Cushing’s disease.

Dogs accepted into the initial clinical trial might also be enrolled in a concurrent therapeutic trial, which is investigating the use of a drug called mycophenolate mofetil to treat SARDS. The costs of all the diagnostic testing and medications are covered by the study.
