Abstract
An ophthalmologic information processing apparatus includes an acquisition unit, a tissue specifying unit, and a specifying unit. The acquisition unit is configured to acquire a tomographic image of a subject's eye formed based on scan data acquired using an optical system for performing optical coherence tomography on the subject's eye. The tissue specifying unit is configured to acquire first shape data representing shape of a tissue of the subject's eye by performing segmentation processing on the tomographic image. The specifying unit is configured to specify a low sensitivity component having a small variation with respect to a change in a position of the optical system with respect to the subject's eye from the first shape data, and to obtain second shape data representing shape of the tissue based on the specified low sensitivity component.
