Abstract: Provided are an ophthalmologic device and a method of controlling the same capable of accurately and reliably acquiring ocular characteristics of a subject eye. The ophthalmologic device includes: a face supporting unit configured to support a face of an examinee; an anterior ocular segment image acquiring unit configured to repeatedly acquire an anterior ocular segment image of the subject eye of the face supported by the face supporting unit; a pupil image detecting unit configured to detect a pupil image of the subject eye for each anterior ocular segment image based on the anterior ocular segment image repeatedly acquired by the anterior ocular segment image acquiring unit; and a determining unit configured to determine whether or not the face is properly supported by the face supporting unit based on a result of detection of the pupil image for each anterior ocular segment image by the pupil image detecting unit.

Abstract: To provide an ophthalmic device in which an operator can objectively grasp a positional relationship between an eye to be examined and an acquisition optical system, and an operability when the operator controls a position or an orientation of the acquisition optical system can be improved, an ophthalmic device includes an acquisition optical system that acquires eye information of an eye to be examined; an electric position change mechanism that changes a position and an angle change mechanism that changes an orientation of the acquisition optical system with respect to the eye to be examined; a display that is visually recognizable by an operator who operates the electric position change mechanism and the angle change mechanism; and a controller that displays, on the display, positional relationship information indicating a positional relationship between the eye to be examined and the acquisition optical system.

Abstract: A fundus camera for reliably performing fundus imaging in a state where no miosis has been caused in the pupil of a subject eye, and a corresponding method. The fundus camera includes a camera main body configured to image the fundus of a subject eye, an anterior ocular segment image acquiring unit configured to repeatedly acquire an anterior ocular segment image of the subject eye at least before the imaging of the fundus by the camera main body, a pupil diameter detecting unit configured to repeatedly detect the pupil diameter of the subject eye based on the anterior ocular segment image repeatedly acquired by the anterior ocular segment image acquiring unit, and an imaging control unit configured to cause the camera main body to image the fundus in a case where the pupil diameter detected by the pupil diameter detecting unit reaches a predetermined first threshold value or more.
