Abstract
An apparatus ( ) for determining a diagnostic glucose level in a human subject includes a light source ( ) that produces collimated light at a selected wavelength. The collimated light is arranged such that it passes through a portion of an eye ( ) of the subject and reflects off an eye lens ( ) at a selected angle (&thgr; ) as reflected light. A polarization analyzer ( ) measures a polarization of the reflected light that exits the eye ( ). A path length processor ( ) determines an optical path length (L ) of the reflected light within an aqueous humor ( ) of the eye ( ). A glucose level processor ( ) computes a glucose concentration based on the measured polarization and the determined optical path length (L ).
