Movie of human retinal capillaries (~7 µm diam) imaged at 500 Hz without (top) and with (bottom) adaptive optics (A0). AO reveals the motion of individual blood cells and allows direct measurement of their velocity without the use of invasive dyes. Variation in brightness between frames is due to photopigment bleaching. [See Rha et al. Fig. 11 for details.]
