Abstract: An ophthalmologic apparatus of an embodiment example includes a front image acquiring device, a first search processor, and a second search processor. The front image acquiring device is configured to acquire a front image of a fundus of a subject's eye. The first search processor is configured to search for an interested region corresponding to an interested site of the fundus based on a brightness variation in the front image. The second search processor is configured to search for the interested region by template matching between the front image and a template image in the event that the interested region has not been detected by the first search processor.

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.
