AOSLO video with AO correction for wavefront aberration at 100 Hz (Visualization 1 ^{(6.8MB, AVI)} ). At the beginning of this video, AO is not turned on and cone photoreceptors are invisible. AO starts at the 5th frame. The brightness, contrast, and resolution were significantly improved. Contiguous cone mosaic is clearly resolved. The image was taken at the nasal retina 0.5 degree away from the foveal center. The frame size is of 0.8 degree X 0.5 degree or approximately 240 μm X 150 μm. The image distortion caused by nonlinear scanning of the resonant scanner was corrected but the distortion caused by eye movements remained. DM1 (Hi-Speed DM97-15, ALPAO SAS, France) was used to correct the wave aberration during the image acquisition.
