  • Patent number: 10064546
    Abstract: An ophthalmic analysis apparatus is the ophthalmic analysis apparatus for obtaining analysis results of tomography images of a subject eye acquired at different dates by ophthalmic optical coherence tomography and outputting statistical information formed based on time-series data of the analysis results, and includes instruction receiving means for receiving selection instructions to select an analytical region on a subject eye from an examiner, and control means for respectively acquiring analysis results in the analytical region selected by the instruction receiving means with respect to tomography images acquired at the different dates and outputting the statistical information.

  • Patent number: 9286674
    Abstract: There is provided an ophthalmic analysis apparatus configured to acquire an analysis result of a tomographic image of a subject eye which is acquired by using optical coherence tomography (OCT), and to output the analysis result. The apparatus functions as a display control unit configured to control a display unit to display a two-dimensional image based on an OCT tomographic image; an analysis region setting unit configured to set multiple analysis regions on the two-dimensional image displayed on the display unit by the display control unit; and an output control unit configured to acquire an analysis result in the multiple analysis regions set by the analysis region setting unit and to output the acquired analysis result.
