The ophthalmologic apparatus includes a light source configured to irradiate a subjects eye, an irradiation optical system arranged between the light source and the subjects eye, a first image forming optical system configured to include a first optical path splitting member for splitting an optical path of the irradiation optical system and form an image of a return light from the subjects eye as a first image, and a second image forming optical system configured to include a second optical path splitting member for splitting an optical path of the irradiation optical system and form an image of a light output from the light source without through the subjects eye as a second image on a different position from that of the first image.
