Abstract: A method for detecting a stressed state, including a step of detecting a stressed state of a subject based on a tomographic image of a choroid of the subject, and a stress detection apparatus including: an image acquisition unit that acquires a tomographic image of a choroid of a subject; a calculation unit that calculates a choroidal thickness or a volume of the choroid based on the tomographic image; and a detection unit that detects a stressed state of the subject based on the choroidal thickness or the volume of the choroid.
