例えば、制御部７０は、視機能に関する層において少なくとも１つの層がなく、信号伝達系に関する層において異常と判定された位置を、視機能と信号伝達系の両方が異常であると判定する。また、制御部７０は、視機能に関する層において少なくとも１つの層がない位置を、視機能が異常である（信号伝達系は正常）と判定し、一方、信号伝達系において異常と判定された位置を、信号伝達系が異常である（視機能系は正常）と判定する。制御部７０は、視機能に関する層において少なくとも１つの層があり、信号伝達系に関する層において正常と判定された位置を、視機能と信号伝達系の両方が正常であると判定する。制御部７０は、これらの判定結果が識別可能な解析マップを表示する。制御部７０は、異常領域と正常領域との割合を示す解析パラメータを表示する。
For example, the control unit 70 determines that there is no abnormality in both the visual function and the signal transmission system at a position where there is no at least one layer in the visual function layer and the layer related to the signal transmission system is abnormal. In addition, the control unit 70 determines that a position where at least one layer is not present in the layer relating to the visual function is determined as abnormal in the visual function (the signal transmission system is normal), while the position determined as abnormal in the signal transmission system. Is determined that the signal transmission system is abnormal (the visual function system is normal). The control unit 70 has at least one layer in the layer related visual function determines that the position is judged to be normal in the layer related to the signal transmission system, both visual function and signaling system is normal. The control unit 70 displays an analysis map in which these determination results can be identified. The control unit 70 displays an analysis parameter indicating the ratio between the abnormal area and the normal area.
