Method for detecting a disease by analysis of retinal vasculature
A method for detecting a disease such as Alzheimer's disease by analysis of retinal vasculature is disclosed. The method for detecting a disease by analysis of retinal vasculature may include applying a combination of optical retro mode illumination techniques to acquire a plurality of amyloid beta plaques and drusen images that are too small to be seen with other imaging modalities. The disease may also be detected with a non-transitory computer storage media having instructions stored thereon which, when executed, execute the method for detecting a disease by analysis of retinal vasculature. The method may track changes in lumen thickness, plaque, size, area and density of the disease by analysis of retinal vasculature over a predetermined period of time.

aligning and combining the frames utilizing one or more super-resolution techniques;
monitoring the aligned and combined frames; and
quantifying changes in the monitored, aligned and combined frames.
2. The method according to claim 1 , wherein the aligning and combining includes the one or more super-resolution techniques that are selected from the group consisting of color fundus imaging, fluorescein angiography, ICG angiography, red-free illumination, IR-retro illumination, hyper spectral imaging or multi-spectral imaging.
