Abstract: An ophthalmologic apparatus includes a main body including a measurement optical system that measures eye characteristics of a subject eye; an anterior ocular segment camera provided in the main body to acquire an anterior ocular segment image by imaging an anterior ocular segment; and a controller that includes an alignment controller configured to control to adjust a relative positional relationship between the subject eye and the main body based on the anterior ocular segment image. The alignment controller includes an imaging start mode controller that is configured, when it is determined that the subject eye does not appear in the anterior ocular segment image in an imaging start mode by the anterior ocular segment camera, to calculate a predicted position of the subject eye based on image recognition of a face part in the anterior ocular segment image and to control movement toward the calculated predicted position.
