  • Patent number: 11026573
    Abstract: Photo-stress by focal light bleaches the retina and temporarily reduced retinal function. Recovery from suppression is measurable by monocular and binocular endpoints, when recovery is prolonged a disease is suspected. The monocular endpoint is the moment the dark central afterimage representing the macula becomes the same brightness as the peripheral ring representing unstimulated retina and the binocular endpoint is brightness equality of rivalrous stimuli. Four embodiments are described for measuring relative brightness sense photo-stress utilizing monocular and binocular methodology.

  • Patent number: 11007109
    Abstract: Active amblyopia therapy is described in this invention where the child actively participates in treatment by viewing binocular stereo image pairs in a game like experience. A method for easily measuring the amblyopic defect prior to each therapy session to validate the progress of therapy is disclosed. Therapy is provided in two embodiments viewable on graphic display devices. My first embodiment controls dominance by switching suppression between the eyes with adjustments in the rivalrous brightness balance. My second embodiment stimulates binocular pathways in both eyes using primeval motion in depth pathways where time delay between stereo images in motion produce insuppressible three dimensional effects.
