Abstract: An ophthalmologic apparatus includes an fixation projection system, an interference optical system, and a controller. The fixation projection system is configured to project fixation light flux onto a fundus of a subject's eye. The interference optical system includes an optical scanner and is configured to split light from light source into measurement light and reference light, to irradiate the subject' eye with the measurement light deflected by the optical scanner, and to detect interference light between returning light of the measurement light from the subject's eye and the reference light. The controller is configured to perform OCT measurement on a first scan region and a second scan region, which are different from each other in the subject's eye, by controlling the interference optical system in a state where a projected position of the fixation light flux on the fundus is fixed.
