Abstract
A method for optical detection of lipofuscin concentrations in the retina is described. A subject's eye is exposed to a light source. Light emitted from the subject's eye is detected. Levels of lipofuscin are determined from the emitted light. A system for optical detection of lipofuscin in the retina is described. The system includes a light source to generate light. The system includes an optical detector in optical communication with the light source. The optical detector is configured to detect light emitted from a subject's eye. A computing device in electronic communication with the optical detector is included in the system to determine levels of lipofuscin from the emitted light.
Claims20
A method for optical detection of lipofuscin concentrations in the retina, the method comprising:
- exposing a subject's eye to a light source, wherein the light source generates light at a wavelength that does not substantially overlap the absorption band of macular carotenoids;
- detecting light emitted from the subject's eye;
- and
- determining levels of lipofuscin from the emitted light.
A system for optical detection of lipofuscin concentrations in the retina, the system comprising:
- a light source to generate light, wherein the light generated by the light source is at a wavelength that substantially overlaps the absorption band of lipofuscin but does not substantially overlap the absorption band of macular carotenoids;
- an optical detector in optical communication with the light source, the optical detector being configured to detect light emitted from a subject's eye;
- and
- a computing device in electronic communication with the optical detector, the computing device being configured to determine levels of lipofuscin from the emitted light.
A system for optical detection of lipofuscin concentrations in the retina, the system comprising:
- a light source to generate light;
- an optical element in optical communication with the light source, the optical element being configured to direct the light to a desired portion of the subject's eye;
- an optical detector in optical communication with the light source, the optical detector being configured to detect light emitted from a subject's eye;
- and
- a computing device in electronic communication with the optical detector, the computing device being configured to determine levels of lipofuscin from the emitted light.
