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 generating clinically valuable analyses and visualizations of 3D volumetric OCT data by combining a plurality of segmentation techniques of common OCT data in three dimensions following pre-processing techniques. Prior to segmentation, the data may be subject to a plurality of separately applied pre-processing techniques.
