Abstract: Disclosed herein are methods and systems for capillary oximetry (e.g., retinal capillary oximetry) using optical coherence tomography (OCT). The method may include obtaining an OCT angiography dataset, performing capillary segmentation based on the OCT angiography dataset to obtain capillary segments, resampling, registering, and/or averaging B-scans of the OCT angiography dataset that correspond to a first capillary segment of the capillary segments to obtain an averaged B-scan for the first capillary segment, determining an anterior and posterior border of the first capillary segment, and determining an oxygen saturation of the first capillary segment based on the averaged B-scan, the anterior border, and the posterior border. Other embodiments may be described and claimed.

Abstract: Disclosed herein is a method for detecting retinal pathologies in three dimensions using structural and angiographic OCT. The method in accordance with the present disclosure may operate by detecting deviations in reflectance and perfusion from a depth-normalized standard retina created by merging and averaging scans from healthy subjects. In one example, the deviations from the standard retina highlight key pathologic features, while depth-normalization obviates the need to segment retinal layers. Additionally, a composite pathology index is disclosed herein that measures average deviation from the standard retina. The present method is amenable to automation and may be implemented in an integrated system and/or provided in the form of software encoded on a computer-readable medium.
