Problems solved by technology

[0042] However, with the conventional fundus observation device, it is not easy to grasp the mutual positional relationship between the two-dimensional image of the fundus surface of the subject's eye obtained by the fundus camera and the tomographic image of the fundus obtained by the optical image measuring device. It is difficult to grasp the state of the gaze part in detail

Abstract

To provide a technology that makes it easy to capture a positional relation of a 2-dimensional image of the surface of a fundus oculi and a tomographic image of the fundus oculi. The fundus observation device 1 is provided with a fundus camera unit 1A for forming a 2-dimensional image of the surface of a fundus oculi Ef of an eye to be examined, an OCT unit 150 for forming a tomographic image of the fundus oculi Ef, a scanning unit 141 as well as an image processing part 220, a display 207, and a controlling part 210 of a computer 200 for displaying the 2-dimensional image formed by the fundus camera unit 1A and a tomographic image formed by the OCT unit, etc. in parallel on the display 207, and also for displaying the cross-sectional position information (attention line L, attention region P) indicating the cross-sectional position of the tomographic image on the surface of the fundus oculi Ef, so as to be overlapped with the 2-dimensional image.

Description

technical field [0001] The present invention relates to a fundus observation device, a fundus image display device, and a storage medium storing a fundus observation program for observing the state of the fundus of an eye to be inspected. Background technique [0002] As a fundus observation device, a fundus camera has conventionally been widely used. FIG. 42 shows an example of an external configuration of a conventional general fundus camera, and FIG. 43 shows an example of an optical system configuration built therein (for example, refer to Patent Document 1.). In addition, the term "observation" includes at least observation of a captured image of the fundus (in addition, observation of the fundus with the naked eye may also be included). [0003] First, referring to FIG. 42 , the appearance structure of a conventional fundus camera 1000 will be described. The fundus camera 1000 includes a gantry 3 mounted on a base 2 so as to be slidable in front, rear, left, and righ...
