Abstract
The ophthalmologic apparatus includes a light source configured to irradiate a subject's eye, an irradiation optical system arranged between the light source and the subject's 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 subject's 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 subject's eye as a second image on a different position from that of the first image.

An ophthalmologic apparatus comprising:
- a light source configured to irradiate a subject's eye;
- an irradiation optical system arranged between the light source and the subject's 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 subject's 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 subject's eye as a second image on a different position from that of the first image.
A method for ophthalmological control, the method comprising:
- irradiating a subject's eye by an irradiation optical system arranged between a light source and the subject's eye;
- forming an image of the light source reflected by the subject's eye as a first image by a first image forming optical system including a first optical path splitting member for splitting an optical path of the irradiation optical system;
- and
- forming an image of the light source without through the subject's eye as a second image on a different position from that of the first image by a second image forming optical system including a second optical path splitting member for splitting an optical path of the irradiation optical system.
