Abstract: A medical diagnostic apparatus includes a receiver circuit that receives three-dimensional data of a subject's eye, and a processor configured to separate portions of the three-dimensional data into separate segments, perform processing differently on each of the separate segments, and combine the separately processed segments to produce a segmented three-dimensional data set. The processor is further configured to generate at least one diagnostic metric from the segmented three-dimensional data set, and the processor is further configured to evaluate a pathological condition based on the at least one diagnostic metric. Related methods and computer readable media are also disclosed.

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.
