Claims

A computer-implemented ophthalmic image processing method comprising:
Acquiring OCT data of the eye to be inspected generated by an image processor based on the spectral interference signal output from an OCT optical system for detecting the spectral interference signal of the measurement light and the reference light guided to the tissue of the eye to be inspected. an acquisition step;
a setting step of setting a depth region including the image position of the tissue as an extraction region for data on one direction side from the zero delay position in the OCT data;
a display control step of extracting extracted OCT data corresponding to the extracted region from the OCT data and displaying it in a predetermined display region on a monitor;
A method of ophthalmic image processing, comprising:

In the setting step, an image position of the tissue in the OCT data is detected, and a distance between the zero-delay position and at least one of an upper end and a lower end of the extraction region is adjusted based on the detected image position. The ophthalmic image processing method of claim 1, wherein

a changing step of receiving an instruction to change at least one of the depth position and range of the extraction region with respect to the OCT data, and changing at least one of the depth position and range of the extraction region based on the instruction; including
In the display control step, when at least one of a depth position and a range of the extraction region is changed based on the instruction, the extracted OCT data displayed in the display region corresponds to the changed extraction region. 3. The ophthalmologic image processing method according to claim 1 or 2 , wherein the image is switched to the one to be performed.

In the display control step, when at least one of the depth position and range of the extraction region is changed based on the instruction, the display mode of the extraction OCT data on the monitor is changed to the extraction region after change. 4. The ophthalmic image processing method according to claim 3 , wherein the method is changed accordingly.

In the acquiring step, acquiring the OCT data containing images of a plurality of tissues located at mutually different positions in the eye to be inspected,
5. The ophthalmologic image processing method according to claim 4 , wherein in said display control step, said display mode is changed according to the type of said image included in said extracted OCT data.

In the acquiring step, acquiring a plurality of OCT data for each of a plurality of predetermined scanning lines;
In the setting step, matching the position of the extraction region with respect to the image position of the subject among the plurality of OCT data,
The ophthalmologic image processing method according to any one of claims 1 to 5 , wherein, in said display control step, said extracted OCT data for each of a plurality of OCT data are sequentially displayed in said display area.

A computer-implemented ophthalmic image processing method comprising:
Acquiring OCT data of the eye to be inspected generated by an image processor based on the spectral interference signal output from an OCT optical system for detecting the spectral interference signal of the measurement light and the reference light guided to the tissue of the eye to be inspected. an acquisition step;
A setting step of setting a depth region including an image position of the tissue in the OCT data as an extraction region, wherein the image position of the tissue is detected, a zero delay position in the OCT data, an upper end of the extraction region and a setting step, wherein the distance between at least one of the bottom edges is adjusted based on the detected image position;
a display control step of extracting extracted OCT data corresponding to the extracted region from the OCT data and displaying it in a predetermined display region on a monitor;
A method of ophthalmic image processing, comprising:

An ophthalmologic image processing program that causes the computer to execute the ophthalmologic image processing method according to any one of claims 1 to 7 by being executed by the processor of the computer.
