Abstract
A fundus analyzing apparatusperforms OCT measurements of a fundus Ef and generates multiple tomographic images that each depict layer structures of the fundus Ef. Each formed tomographic image is stored in a storage. Based on the pixel values of the pixels of each tomographic image, the layer-region identifying partidentifies the layer region corresponding to the pigment layer of the retina. Based on the shape of the layer region, the curve calculatorobtains a convex standard curve in the direction of depth of the fundus Ef. Based on the layer region and the standard curve, a protrusion-region identifying partidentifies protrusion regions where the layer region protrudes in the opposite direction from the direction of depth of the fundus Ef. A morphological-information generating partgenerates morphological information representing the morphology (number, size, distribution, etc.) of the protrusion regions.
