Amyloids accumulate in the brain but also in the eyes--those windows to the soul that just so happen to be excellent windows into the cranium as well. Using an ointment or eyedrops loaded with these fluorescent markers, the hope here is that doctors could light up amyloids in the eye in different colors, with each color corresponding to distinctive physical properties of the amyloid and the disorder it is associated with. Rather than resorting to somewhat unreliable diagnostics for neurodegenerative disorders--diagnostics that rely on amyloid targeting radioactive molecules and PET scans--the clinician could see the color of the patient's condition right there in his or her eyes.
