System and method for extracting morphological change in the optic nerve head for generating axial length of eyeball

摘要

The present invention obtains 3D pre-exercise images through tomography of the optic nerve papilla before adduction or abduction, and acquires 3D post-exercise images through tomography of the optic nerve papilla after adduction or abduction. ); A difference calculator configured to compare the pre-exercise image and the post-exercise image to obtain an area having a difference in optic nerve papillas, and to calculate an area of the difference area; Axial length measuring unit for measuring the axial length for the subject of the pre-exercise and the post-exercise image; And evaluating the relationship between the area of the difference region for each of the plurality of subjects obtained by the 3D OCT, the difference calculation unit and the axle length for each of the plurality of subjects measured by the field measurement unit. Morphological analysis of the optic nerve papilla for calculating the axial length, including; a statistical analysis unit which provides the statistical data as an index for calculating the axial length or neuropathy through the area of the difference region for a specific person. A change extraction system and method are disclosed. According to the present invention, by accurately calculating the morphological changes of the optic nerve papilla occurring in both abduction and adduction, the ability of morphological changes of the optic nerve papilla can be considered as an effect of eye movement and physical properties of the optic nerve.
