Figure 1.

OCTA images of superficial retinal layer vasculature in a psychiatrically healthy control subject (top left) that was age-matched to a later-episode schizophrenia patient (bottom left). Reduced microvasculature density is clearly visible in the lower image (see also Figures 2–4 for additional information). The foveal avascular zone is highlighted with a red border. This region was larger in the schizophrenia sample (see Table 3). The same subsection of each image, bounded by a yellow square, is enlarged and shown to the right of each primary image. Microvasculature reduction is more easily visible in these enlargements, despite the lowered resolution.
