Effects of Elevated IOP on Ganglion - Cell Photoreceptors Matthew Van Hook, PhD University of Nebraska Medical Center (Omaha, NE)

In the last 10 years we've been working really hard at seeing the photoreceptors and studying other retina conditions but we're now going to focus really hard on trying to visualize the ganglion cells and the vasculature that serves the ganglion cells so that we can actually test some of the most contested hypotheses about glaucoma.
