Method and apparatus for optical imaging of retinal function
First Claim
1. A method for optical imaging of retinal function comprising:
- an illuminating observing step of illuminating the retinal region of the rear surface of an eyeball including the macular area and the optic disk with an invisible light and observing the retinal region;
a stimulating step of illuminating the retinal region with a visible flash light to stimulate a retinal function including an optic disk'"'"'s function;
an imaging step of capturing images A, B before and after the stimulation of the retinal region illuminated with the invisible light; and
a calculating step of detecting the change of the retinal function of the retinal region from the images A, B before and after the stimulation, wherein, in the calculating step, the images A, B before and after the stimulation are registered in advance and the change of the retinal function is displayed with an image from the registered images.

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.

6. An apparatus for optical imaging of retinal function comprising:
-
a stimulator for illuminating the retinal region of the rear surface of an eyeball including the macular area with a visible flash light to stimulate a retinal function including an optic disk'"'"'s function;
an illuminator for illuminating the retinal region with an invisible light;
an imaging device for capturing images A, B before and after the stimulation of the retinal region illuminated with the invisible light; and
a calculator for detecting the change of the retinal function of the retinal region from the images A, B before and after the stimulation, wherein the calculator has an image processing program for registering the images A, B before and after the stimulation in advance and subsequently displaying the retinal function with an image from the registered images by using a computer. - View Dependent Claims (7, 8, 9)
