摘要： An ocular fundus portion analyzer and the method are provided for attaining accurate and quick detection and diagnoses of an ocular fundus defect portion, such as an excavation of an optic disk caused by glaucoma and a macula retinae caused by retinal detachment, by dealing with a large number of single-shot ocular fundus images, for example, taken in physical examinations. It is configured to include an image importing portion for importing an image of an ocular fundus portion taken by a visible radiation or a near-infrared radiation; a pixel data generation portion for generating pixel data including pixel positions and luminance of pixels constituting the image; a local plane gradient image generation portion for generating a three-dimensional image from pixel positions and luminance of the pixel data, obtaining a local approximation plane at any pixel and generating a local plane gradient image from a gradient angle with respect to a control plane of the three-dimensional image; and a display portion for displaying the local plane gradient image.
