  • Method and apparatus for optical imaging of retinal function
    Patent number: 7370967
    Abstract: A method for optical imaging of retinal function comprises an illuminating observing step (S1) of illuminating the retinal region (2) of the rear surface of an eyeball (1) including the macular area and the optic disk with an invisible light (3) and observing the retinal region (2), a stimulating step (S3) of illuminating the retinal region (2) with a visible flash light (4) to stimulate a retinal function including an optic disk's function, an imaging step (S2) of capturing images (A, B) before and after the stimulation of the retinal region (2) illuminated with the invisible light, and a calculating step (S4) of detecting the change of the retinal function of the retinal region from the images (A, B) before and after the stimulation. In the calculating step, the images (A, B) before and after the stimulation are registered in advance, and the change of the retinal function of the retinal region is displayed with an image from the registered images.
