Zusammenfassung:	Embodiments relate to a method for detecting a change of a fundus and to a device performing the same. The method include the steps of: acquiring first and second fundus images taken respectively at first and second time points of the eye of a subject; matching the first and second fundus images based on intraocular blood vessels; detecting the region of interest in the first fundus image and the region of interest in the second fundus image from the matched image; and, based on the region of interest image in the first fundus image and the region of interest in the second fundus image, detecting a fundus change from the first time point to the second time point. 실시예들은 대상자의 안구를 제1 및 제2 시점에서 각각 촬영한 제1 및 제2 안저영상을 획득하는 단계; 안구 내 혈관에 기초하여 제1 및 제2 안저영상을 정합하는 단계; 및 정합 영상에서 제1 안저영상 내 관심영역 및 제2 안저영상 내 관심영역을 검출하는 단계; 및 제1 안저영상의 관심영역 영상과 제2 안저영상 내 관심영역 영상에 기초하여 제1 시점에서 제2 시점 동안의 안저 변화를 검출하는 단계를 포함한 안저 변화 검출 방법 및 이를 수행하는 장치에 관한 것이다.
