FUNDUS ANALYSIS DEVICE AND FUNDUS ANALYSIS METHOD |
摘要 |
Disclosed is a technique that allows the effective detection of drusen in the fundus. A fundus analysis device (1) subjects the fundus (Ef) to OCT measurement and forms a plurality of tomographic images that respectively depict the layer structure of the fundus (Ef). Each tomographic image which is formed is stored in a storage unit (212). A layer region identifying unit (233) identifies a layer region equivalent to the pigment layer of the retina on the basis of the pixel values of pixels of each tomographic image. A curve calculation unit (234) determines the reference curve protruding in the direction of the depth of the fundus (Ef) on the basis of the shape of the layer region. A protruding region identifying unit (235) identifies, on the basis of the layer region and the reference curve, protruding regions wherein the layer region protrudes opposite to the direction of the depth of the fundus (Ef). A form information generation unit (236) generates form information relating to the forms (the number, sizes, distribution, etc.) of the protruding regions. |
