Visualization of individual cells in the living retina is critical to understanding normal retinal structure and its changes with disease. Advances in adaptive optics scanning laser ophthalmoscopy have made it possible to image the living retina with better resolution than ever before, making it possible to see the smallest retinal cells including cones at the foveal center, individual rods and blood cells flowing through the smallest capillaries. In vivo two-photon fluorescence imaging of the retina has the potential to not only provide images of cellular structure, but also probe retinal function in the healthy and diseased eye. Changes in fluorescence signal over time provide information about the rate of early stages in the visual cycle in the living eye. New advances in technology will further improve efficiency and aim towards safely imaging in humans.
