Ophthalmic analysis apparatus and ophthalmic analysis program

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 ophthalmic analysis apparatus comprising:

• a processor;
• and
• a memory storing computer readable instructions, when executed by the processor, causing the ophthalmic analysis apparatus to function as:
• a display control unit configured to control a display unit to display a two-dimensional image which is one of an OCT tomographic image, a two-dimensional front image whose position is associated with three-dimensional OCT data formed from an OCT tomographic image in each line, a two-dimensional analysis map which is calculated based on three-dimensional OCT data formed from an OCT tomographic image in each line, and a two-dimensional analysis chart which is calculated based on three-dimensional OCT data formed from an OCT tomographic image in each line;
• 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;
• wherein the memory further stores instructions, when executed by the processor, causing the ophthalmic analysis apparatus to function as a characteristic site detection unit configured to detect a position of a fovea centralis and a position of a papilla in the two-dimensional image, and
• wherein the analysis region setting unit is configured to set a center line based on the position of the fovea centralis and the position of the papilla which are detected by the characteristic site detection unit, and to set a first analysis region and a second analysis region to be symmetric with respect to the center line.

A non-transitory computer-readable medium having a computer program stored thereon and readable by a computer configured to acquire an analysis result of a tomographic image of a subject eye which is acquired by using optical coherence tomography (OCT), the computer program, when executed by the computer, causing the computer to perform operations comprising:

• controlling a display unit to display a two-dimensional image which is one of an OCT tomographic image, a two-dimensional front image whose position is associated with three-dimensional OCT data formed from an OCT tomographic image in each line, a two-dimensional analysis map which is calculated based on three-dimensional OCT data formed from an OCT tomographic image in each line, and a two-dimensional analysis chart which is calculated based on three-dimensional OCT data formed from an OCT tomographic image in each line;
• setting multiple analysis regions on the two-dimensional image displayed on the display unit by the display control unit;
• and
• acquiring an analysis result in the multiple analysis regions set by the analysis region setting unit and outputting the acquired analysis result;
• and
• wherein the analysis result is an integrated analysis result by calculating ratios or differences between analysis results for each of the set multiple analysis regions.
