  • Systems and methods of infrafred psychophysical measurement
    Patent number: 10856734
    Abstract: A system for examination of an eye of a subject includes a laser for irradiating a select portion of the retina with a short pulse light having a wavelength of about 800 nm to about 1400 nm at an intensity effective to stimulate two photon induced isomerization of visual pigments in the select portion of the retina of the subject's eye, and an input device to permit the subject to input a reaction or response of the subject to the irradiating light.
    Type: Grant
    Filed: May 30, 2018
    Date of Patent: December 8, 2020
    Assignee: POLGENIX, INC.
    Inventors: Grazyna Palczewski, Katarzyna Komar, Patrycjusz Emplewski, Maciej Wojtkowski

  • TWO-PHOTON MICROSCOPY IMAGING RETINA CELL DAMAGE
    Publication number: 20160345827
    Abstract: A method of determining retinal degeneration of photoreceptors and/or the retinal pigment epithelium (RPE) of a subject includes measuring two-photon induced fluorescence inner and/or outer segments of the photoreceptor cells and/or retinal pigment epithelium to assess photoreceptor cell death and retinal pigment epithelium cell death or degeneration.
