The image is an overlay of 3 images representing the distribution of the 3 most abundant fluorophore signals that were extracted using advanced factorization algorithms. The 3 images were digitally colored red (1), green (2) and blue (3). The signals localized to different components in the RPE as illustrated by color mixing: normal RPE cells (light blue), RPE Cells stacked at the edge of drusen creating a halo effect (light green), main body of drusen (blue) with a distinct central signal (pink) that also localizes to sub-RPE deposits (red).This method demonstrates that distinct fluorophore signals are localized specifically to drusen in AMD tissues.
