A fundus oculi observation device comprises: a first image forming part for optically obtaining data and then forming a fluorescence image of a fundus oculi of an eye administered with a fluorescent agent in advance based on the obtained data; a second image forming part for optically obtaining data and then forming a tomographic image of the fundus oculi based on the obtained data; a display; and a controller for causing said display to display said fluorescence image formed by said first image forming part side-by-side with said tomographic image formed by said second image forming part, as well as to display cross-sectional position information that represents a cross-sectional position of said tomographic image in said fluorescence image by overlapping it with said fluorescent image.

Fundus oculi observation device, a fundus oculi image display device and a fundus oculi image display method

A fundus examination apparatus includes an illumination optical system (), which illuminates a fundus by fundus illumination light, an imaging optical system (), which photographs a fundus image based on a polarization property of reflected illumination light, and a picture signal processing device, which processes a signal output from the imaging optical system; and the imaging optical system includes a phase plate array () that a plurality of unit constitutional plates (U) is arranged in a matrix in a plane; each of the unit constitutional plates comprising four or more micro phase plates (-), a polarizer (), which polarizes the reflected illumination light passing through the phase plate array () into a predetermined polarization direction, and an image pickup device () that a plurality of constitutional units (U) is arranged in a matrix in a plane; each of the constitutional units comprising four or more pixels (G-G).
