The invention provides methods for the use of Raman spectroscopy to non-invasively detect molecular characteristics of the constituents of the aqueous humor, vitreous humor, lens or retina. The method can be employed for the detection of molecular changes underlying ocular pathologies. In one embodiment of the invention, the method involves the steps of introducing light into the eye of the subject using a laser; collecting Raman spectra emitted from the eye; dispersing the collected Raman spectra onto a detector; and analyzing detected Raman spectral data to identify a molecular change related to an ocular pathology. The non-invasive method provided by the invention makes use of techniques and equipment that enable detection of Raman spectra with light intensities that fall within acceptable safety standards.
