Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of facilitating grasping of whole fundus of an eye to be examined which is an inspection object, even when stimulus light is applied to an intraocular part of an eye to be examined, and a fixation direction of an eye to be examined is deviated from a center of an optic axis of an illumination optical system.SOLUTION: An ophthalmologic apparatus comprises: fundus image photographing means for photographing a fundus of an eye to be examined; and display means for displaying a reference fundus image of an eye to be examined which was acquired in advance by the fundus image photographing means. The reference fundus image is an image of a fundus of the eye to be examined which is photographed in a state in which no stimulus light is radiated to the intraocular part of the eye to be examined, and a fixation direction of the eye to be examined almost matches to an optic axis of the illumination light. A lightness of a peripheral part of the reference fundus image is higher than a lightness of a peripheral part of the fundus image of the eye to be examined which his acquired by the fundus image photographing means when the illumination light and stimulus light are radiated to the fundus of the eye to be examined, and is higher than a lightness of the peripheral part of the fundus image of the eye to be examined acquired by the fundus image photographing means when the fixation direction of the eye to be examined is deviated from the optic axis of the illumination light.SELECTED DRAWING: Figure 4
