PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of calculating a movement amount of an eye to be examined based on position information on a plurality of blood vessel characteristic regions acquired by the scanning of light by scanning means.SOLUTION: An ophthalmologic apparatus which includes scanning means (SLO-XY scanner) for scanning light for an eye to be examined acquires an image of the eye to be examined on the basis of the return light from the eye to be examined irradiated with the light scanned by the scanning means, and extracts a plurality of blood vessel characteristic regions (blood vessel branch parts) from the acquired image. A movement amount of the eye to be examined is calculated on the basis of the position information on the plurality of blood vessel characteristic regions acquired by the scanning of light by the scanning means for each of the plurality of blood vessel characteristic regions.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】走査手段により光が走査されることで得た複数の血管特徴部位の位置情報に基づいて被検眼の移動量を算出可能な眼科装置を提供する。【解決手段】被検眼に対して光を走査する走査手段(SLO-XYスキャナ)を備え、走査手段により走査された光を照射した被検眼からの戻り光に基づいて被検眼の画像を取得し、取得された画像から複数の血管特徴部位(血管分岐部)を抽出する。複数の血管特徴部位それぞれに対して走査手段により光が走査されることにより得た複数の血管特徴部位の位置情報に基づいて、被検眼の移動量を算出する。【選択図】図3
