    Abstract: Optical Coherence Tomography Angiography (OCTA) image representation is obtained having OCTA pixels assigned respective OCTA values. A vessel density map is computed from the OCTA image representation. A fractional deviation map and/or a pattern deviation map is computed for the patient from the vessel density map and a normative database, wherein: (1) the fractional deviation map represents a percent loss of vessel density at each pixel location relative to an expected value based on the normative database; and (2) computing the pattern deviation map includes: computing a pattern map of the vessel density representing a normalized vessel density pattern of the vessel density map relative to an average value of the vessel density map; and computing the pattern deviation map using the pattern map. A loss is determined by using at least one of the fractional deviation map and the pattern deviation map. Other features are also provided.

    Abstract: An imager that can provide separated images corresponding to differing depths in a sample is presented. In accordance with some embodiments of the invention, an imager can include a light source; a sample arm that receives light from the light source, directs the light to a sample, and captures light returning from the sample; a modulation source that provides different modulations corresponding to differing imaging depths in the sample; a detector system to receive the captured light from the sample with the different modulations; and a processor that receives signals from the detector system and separates a plurality of images corresponding with the differing image depths in the sample.
