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 imaging apparatus of an embodiment includes a data acquisition device, photographing device, a controller, and an error detector. The data acquisition device acquires data by scanning a subject's eye using optical coherence tomography. The photographing device photographs the subject's eye to obtain a front image. The controller controls the data acquisition device to perform a series of scans along a preset path group. The error detector detects an error based on a series of data acquired by the series of scans and two or more front images that include one or more front images obtained by photographing device corresponding to the series of scans.
