Dr. Nork’s research focuses on the mechanisms by which various ocular diseases affect the outer retina (especially the rods and cones) and how injury to the outer retina might, in turn, affect disease pathogenesis. For example, Dr. Nork and his colleagues have found selective blue cone loss in retinal detachment and diabetic retinopathy. They have also found evidence that the retinal cones may are injured in glaucoma–a disease that is not traditionally associated with the outer retina. Working with other members of the Department, they have described morphologic changes in the photoreceptors in post-mortem human eyes that were donated by people who carried a diagnosis of glaucoma. Further confirmatory studies with animal models of glaucoma have shown anatomic, biochemical and functional effects on the cones. His lab is currently studying the role that photoreceptor injury may play in the pathogenesis of vision loss in glaucoma.
