    摘要: A fundus oculi observation device capable of defining which part in the result of analysis of the layer thickness of a fundus oculi is a part obtained by analyzing a vascular region is provided. A fundus oculi observation device 1 forms a plurality of tomographic images G1-Gm of a fundus oculi Ef. A layer thickness distribution calculator 231 calculates layer thickness distribution of the fundus oculi Ef in a cross section of a tomographic image G based on the tomographic images G1-Gm. A vascular region specifying part 234 specifies a vascular region in the tomographic image G. A controller 210 controls a display 240A to display layer thickness distribution information representing the layer thickness distribution and to also display vascular position information representing the position of the vascular region on the layer thickness distribution information.

    摘要: The fundus observation apparatus 1 has a function to form tomographic images and 3-dimensional images of a fundus Ef by scanning signal light LS as well as a function to form a moving image (observation image K) of a fundus Ef during OCT measurement. Furthermore, the fundus observation apparatus 1 includes an x-correction part 231 and a y-correction part 232 for correcting a position in the fundus surface direction of the 3-dimensional image based on the observation image K, and a z-correction part 233 for correcting the position in the fundus depth direction of a 3-dimensional image, based on a tomographic image Gi of the fundus Ef based on the detection results of interference light LC of separately scanned signal light LS and reference light LR.

    摘要: A fundus oculi observation device 1 can form a near-infrared motion image and a color image (still image) of a fundus oculi Ef. The device 1 specifies an image region within the near-infrared motion image corresponding to a region of interest within the color image while the near-infrared motion image is being formed. The device 1 scans with a signal light LS based on the specified image region, thereby forming a tomographic image along the scanning line. According to the device 1, it is possible to determine a region of interest within a still image having a comparatively high image quality, specify the image region within the motion image corresponding to this region of interest, set a measurement site for the tomographic image.
