Figure 1.

Example horizontal line scans. Three images (top row) each covering 30 degrees of retina were acquired for each eye for each subject and then montaged together into a single image (bottom row, left). The relative scales of the montaged scans are shown overlaid on a color fundus photograph from the same subject (bottom row, right). The GCL and IPL in each montaged image were manually labeled. The borders (shown as yellow, green, and red) defined by these labels were smoothed with a spline.
