In accordance with an embodiment of the invention, there is provided a device and method for detecting an amyloid protein in an eye of a mammal. A method comprises illuminating the eye with a light source having at least one of a wavelength property, a polarization property or a combination thereof, each appropriate to produce fluorescence in at least an amyloid-binding compound when the amyloid-binding compound is bound to the amyloid protein, the amyloid-binding compound having been introduced to the eye and specifically binding to the amyloid protein indicative of the amyloidogenic disorder; and determining a time decay rate of fluorescence for at least the fluorescence produced by the amyloid-binding compound bound to the amyloid protein, the determining permitting distinguishing of the presence of the amyloid-binding compound bound to the amyloid protein in the eye based on at least the time decay rate.

System and method for detecting amyloid proteins

A system for performing at least one of quasi-elastic light scattering and fluorescent ligand scanning on a subject's eye includes a light source configured to transmit light toward the subject's eye, a lens configured to focus light sent from the source and received from the subject's eye, a measurement reflector disposed to receive at least a portion of the focused light and configured to reflect a first portion of the received light, a camera configured and disposed to receive the first portion of the received light and configured to provide indicia of an image corresponding to the first portion of the received light, and a processor coupled to the camera and configured to analyze intensities of light in the image to determine a location of a reference point corresponding to an interface of a portion of the eye.
