Optical coherence tomography angiography (OCTA) images and quantification of retinal capillary changes in a subject with cognitive impairment and control. The figure shows 3 × 3mm2 parafoveal OCTA images of two subjects with CDR-SOB scores = 0 and CDR-SOB = 1, and ages 76 and 73 years, respectively. Neither subject has diabetes but both have hypertension. Images on the second and third columns show the corresponding skeletonized images and pseudo-colored maps of the capillary density. The subject with CDR-SOB = 0 has more localized areas of higher capillary density than the age and medical condition similar subject with CDR-SOB >0.
