Abstract
A method and apparatus for non-invasive in vivo inspection of ocular tissue wherein a laser provides a low power, coherent and uniform output beam of light which is guided through the optical system of a modified slit lamp biomicroscope to the eye of a patient for scattering by protein molecules in the ocular tissue of the patient, and scattered laser light in the ocular tissue is viewed through the slit lamp to visually align a pick up associated with the slit lamp optical system to a desired location in the ocular tissue. A measurement is performed by receiving laser light scattered from the ocular tissue and converting the scattered light into an electrical signal, and the electrical signal is analyzed by sorting it into components each characterized by an intensity and a fluctuation rate and each component associated with a protein group in the ocular tissue.
