  • Rapid measurement of individual cone photoreceptor pointing for evaluation of eye health using focus diversity
    Patent number: 10231618
    Abstract: Systems and methods are described for measuring angular direction of individual photoreceptors in an eye. A light source is projected through the pupil of the eye onto the retina. An image of the light reflected back from the plurality of photoreceptors is captured at a first focal depth and then at a second focal depth, where the first focal depth is different than the second focal depth. At least one individual photoreceptor is identified in both images and a lateral difference of the position of the identified photoreceptor is measured. The angular direction of the photoreceptor is then calculated based on the measured lateral difference.
