Ophthalmologic image processing method and OCT apparatus

An ophthalmologic image processing method performed by a computer, the method comprising:

• an acquisition step of acquiring OCT data of an eye to be examined generated by an image processor based on a spectral interference signal output from an OCT optical system, the OCT optical system detecting the spectral interference signal between measurement light guided to a tissue of the eye to be examined and reference light;
• a setting step of setting a depth region including an image position of the tissue as an extraction region for data on one-direction side from a zero delay position in the OCT data;
• and
• a display control step of extracting extracted OCT data corresponding to the extraction region from the OCT data and displaying the extracted OCT data in a display region set in advance on a monitor.
