Abstract: 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.

Abstract: A fundus oculi observation device 1 has a function of forming a tomographic image of a fundus oculi Ef and a function of capturing a two-dimensional image of the surface of the fundus oculi Ef (a fundus oculi image Ef?). An arithmetic and control unit 200: specifies a vascular region in the tomographic image and a vascular region in the fundus oculi image Ef?; obtains a common region of the vascular region in the tomographic image and the vascular region in the fundus oculi image Ef? and specifies the common region in the tomographic image; erases an image of the common region from the tomographic image and estimates a layer position within the common region to add an image representing this layer position to the common region; and obtains the layer thickness of the fundus oculi Ef in the common region based on the image representing this layer position.
