| 1. A non-invasive in vivo method for assessing carotenoids in the retina and/or macula, comprising:
performing Optical Coherence Tomography (OCT) on a retina of a subject to obtain absorption and/or reflectance spectral data
correlated with carotenoid levels; and
generating a spatial representation of carotenoid levels in the retina based on comparing the spectral data from the OCT of
the retina with a priori reference spectra.
