OCTA and AO-OCTA images of a patient with diabetic retinopathy. (A) Overview OCTA image recorded with a commercial instrument (the red square indicates the region of interest that has been imaged using AO-OCTA). (B) Enlarged region of interest (indicated by the red square in (A) depth integrated over the anterior layers (region 1 and 2 in Fig. 2). (C) The same region as in (B) but depth integrated over deeper retinal layers (region 3 and 4 in Fig. 2). (D) OCT B-scan recorded at the center of the region of interest shown in (A). (E) En-face AO-OCTA image depth integrated over the region between the green lines shown in (G). (F) En-face AO-OCT intensity image depth integrated over the same region as in (E). (G) AO-OCTA B-scan showing the microaneurysm (H) AO-OCT intensity image at same location as in (G). The red arrows in the images show the location of a microaneurysm. The green arrows point to a hard exudate. The blue arrows indicate a small capillary that appears to perform a twisted loop and is embedded in highly scattering media.
