Abstract: The ophthalmological device of an embodiment includes an optical system for inspection, a display, a subject's eye position acquiring unit, and a control unit. The optical system for inspection includes a photographic optical system for photographing an eyeground of the subject's eye. The subject's eye position acquiring unit acquires a three-dimensional position of the subject's eye. The control unit acquires information on positional displacement of the optical system for inspection with respect to the subject's eye on the basis of the three-dimensional position to cause a screen of the display to display two alignment index images to be varied in position with respect to a reference position of alignment preset in the display in a pseudo manner, in accordance with the information on positional displacement.

Abstract: An ophthalmologic information processing apparatus includes an analyzer, a storage unit, a region editing unit, and a display controller. The analyzer is configured to analyze data of a subject's eye optically acquired by projecting light onto the subject's eye, and to specify a lesion region in the subject's eye. The storage unit stores image data of the subject's eye. The region editing unit is configured to specify a changed region by changing the lesion region based on operation information corresponding to an operation content on an operating unit. The display controller is configured to cause an image of the subject's eye to be displayed on a display means based on the image data stored in the storage unit, and to cause a region corresponding to the changed region in the image of the subject's eye to be displayed so as to be identifiable.

Abstract: An ophthalmologic information processing apparatus includes an analyzer, and a display controller. The analyzer is configured to specify one or more atrophy regions in a fundus of a subject's eye by analyzing data of the fundus acquired using optical coherence tomography. The display controller is configured to cause a plurality of images, each of which represents the one or more atrophy regions specified by the analyzer, to be displayed on a display means in chronological order, based on the plurality of data acquired at different timings.

Abstract: An ophthalmologic information processing apparatus includes a reference data setting unit, a first region specifying unit, and a second region specifying unit. The reference data setting unit is configured to set, as first reference data, first fundus data among a plurality of fundus data of a fundus of a subject's eye acquired at different acquisition timings using optical coherence tomography. The first region specifying unit is configured to specify one or more first atrophy regions in the fundus by analyzing the first reference data. The second region specifying unit is configured to specify one or more second atrophy regions by analyzing second fundus data based on the one or more first atrophy regions, the second fundus data being acquired after the acquisition timing of the first reference data among the plurality of fundus data.
