A system for performing quasi-elastic light scattering and fluorescent ligand scanning on a subject's eye, the system comprising: a display screen showing an image of the eye to allow an operator to select locations in the eye to be measured; and an optical unit coupled to a processor for executing quasi-elastic light scattering and fluorescent ligand scanning on selected locations of the eye and for collecting data associated with quasi-elastic light scattering and fluorescent ligand scanning performed, wherein the processor displays the data on the display screen for review by the operator, wherein the data collected includes the average density of scattered light associated with quasi-elastic light scattering performed and the average fluorescence intensity associated with fluorescent ligand scanning performed; the system further comprising means for determining a ratio (FLS Norm) between the average fluorescence intensity (I FLS-N) associated with fluorescent ligand scanning of a location in the nucleus region of the lens of the eye and average fluorescence intensity (I FLS-SN) associated with fluorescent ligand scanning of a location in the supranucleus region of the lens of the eye in accordance with the equation FLS Norm = I FLS-SN /I FLS-N and means for determining a ratio (QLS Norm) between the average intensity (I QL5-N) of scattered light associated with quasi-elastic light scattering at a location in the nucleus region of the lens of the eye and average intensity (I QLS-SN) of scattered light associated with quasi-elastic light scattering at a location in the supranucleus regio of the lens of the eye in accordance with the equation QLS Norm = I QLS-SN /I QLS-N, where an increase in FLS Norm or QLS Norm indicates an increase in the presence of a material or object in the eye. a display screen showing an image of the eye to allow an operator to select locations in the eye to be measured; and an optical unit coupled to a processor for executing quasi-elastic light scattering and fluorescent ligand scanning on selected locations of the eye and for collecting data associated with quasi-elastic light scattering and fluorescent ligand scanning performed, wherein the processor displays the data on the display screen for review by the operator, wherein the data collected includes the average density of scattered light associated with quasi-elastic light scattering performed and the average fluorescence intensity associated with fluorescent ligand scanning performed; the system further comprising means for determining a ratio (FLS Norm) between the average fluorescence intensity (I FLS-N) associated with fluorescent ligand scanning of a location in the nucleus region of the lens of the eye and average fluorescence intensity (I FLS-SN) associated with fluorescent ligand scanning of a location in the supranucleus region of the lens of the eye in accordance with the equation FLS Norm = I FLS-SN /I FLS-N and means for determining a ratio (QLS Norm) between the average intensity (I QL5-N) of scattered light associated with quasi-elastic light scattering at a location in the nucleus region of the lens of the eye and average intensity (I QLS-SN) of scattered light associated with quasi-elastic light scattering at a location in the supranucleus regio of the lens of the eye in accordance with the equation QLS Norm = I QLS-SN /I QLS-N, where an increase in FLS Norm or QLS Norm indicates an increase in the presence of a material or object in the eye.
