Claim 10:
11. An ophthalmologic apparatus, comprising:
an Optical Coherence Tomography (OCT) scanner configured to acquire a tomographic image of a subject's eye using optical coherence tomography; and
an ophthalmologic information processing apparatus for analyzing the tomographic image of the subject's eye formed by arranging a plurality of A-scan images acquired by performing an OCT scan on an inside the subject's eye with measurement light deflected around a scan center position, the ophthalmologic information processing apparatus including processing circuitry configured to
transform pixel positions in the image into transformation positions along traveling directions of the measurement light passing through the scan center position by transforming pixel positions in each A-scan image into transformation positions along the traveling directions of the measurement light used to form the A-scan image,
specify a layer region by analyzing the image in which the pixel position has been transformed, and
specify a normal direction of the layer region.
