  • Apparatus for use in the measurement of macular pigment optical density and/or lens optical density of an eye
    Patent number: 10456028
    Abstract: An apparatus for use in the measurement of the optical density of macular pigment in the human eye, and an apparatus for the use in measuring the lens optical density of a human eye. The apparatus is particularly applicable to flicker photometers, which are used to measure the macular pigment in the human eye.

  • Macular pigment measurements
    Publication number: 20050010115
    Abstract: Apparatus for use in measuring the density and spatial distribution of macular pigment in an eye comprises a camera (4) for capturing a colour image of an eye, at least one filter (36) for filtering light reaching the camera (preferably by filtering the light illuminating the eye). The filter (36) has a transmission spectrum with one peak in the region of light absorbed by the pigment and another peak in a region where no such absorption occurs. The filter increases the sensitivity of the camera to macular pigment whilst enabling the effect of other pigments to be reduced or eliminated. A method of measuring macular pigment involves obtaining a colour image of an eye, the image having two colour components each having a spectrum having a respective one of said peaks.
