Abstract:
An ophthalmologic apparatus includes: an objective lens 18 configured to face a subject's eye E; an illumination optical system 1c configured to irradiate the subject's eye E with illumination light L1; a measurement optical system 1 b configured to take an interference image of corneal reflection light R1, which is a reflection of the illumination light L1, through the objective lens 18; an observation optical system 1a configured to image an anterior segment of the subject's eye E through the objective lens 18; a control unit 2 configured to process information on imaging by the measurement optical system 1b and the observation optical system 1 a; and the control unit 2 configured to simultaneously output, to a single output unit 3, tear film information calculated from the interference image by the measurement optical system 1 b, and information on the anterior segment E imaged by the observation optical system 1a.
