Abstract: An ophthalmologic information processing apparatus includes an analyzer, a storage unit, and a display controller. The analyzer is configured to specify an atrophy region in a fundus by analyzing data of the fundus of a subject's eye acquired using optical coherence tomography. The storage unit stores image data of the fundus. The display controller is configured to cause a fundus 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 atrophy region in the fundus image to be displayed on the display means 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 ophthalmological device of some embodiment examples includes a memory, detecting processor, identifying processor, transforming processor, and composing processor. The memory stores a plurality of angiograms acquired by applying optical coherence tomography to an eye fundus. The detecting processor is configured to detect a feature point from each of the angiograms. The identifying processor is configured to identify a plurality of feature point groups from among a plurality of feature points detected from the angiograms. Each feature point group corresponds to a same site of the eye fundus. The transforming processor is configured to transform at least part of the angiograms based on the feature point groups. The composing processor is configured to compose two or more angiograms of the angiograms at least part of which has been transformed, based on the feature point groups.

Abstract: A storage device of an ophthalmologic image display device of an embodiment stores a three dimensional data set acquired by scanning a subject's eye using OCT. An image processor forms, based on the three dimensional data set, a B-mode image, front images, and composite front image obtained from the front images. A display controller displays the B-mode image, front images and composite front image in a predetermined layout. The display controller displays distinguishment color information for distinguishment between the front images by colors and slice area information that indicates a partial region of the B-mode image corresponding to a slice area of the three dimensional data set represented by each front image in a color according to the distinguishment color information, and displays a composite front image based on the front images, each of which is expressed by a color according to the distinguishment color information.

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.
