Figure 6
Examples of automatic artifact detection. All images are full retinal projections of 12 mm × 12 mm fields. Column (A) 68 year-old with mild NPDR; same as eye as in Fig. 3. Column (B) 74 year-old with severe NPDR. Column (C) 54 year-old with severe NPDR. Column (D) Right eye from same patient as column (C) PDR. Row 1: En face OCTA image of retinal vasculature. Row 2: Corresponding en face OCT image. Row 3: Automatically detected artifacts shown in red. Row 4: Uncorrected non-perfusion areas. Row 5, corrected non-perfusion areas. PNPAs are listed in the top-right corner of each panel in Row 4 and Row 5. The white arrowhead in column (D) points to a region that was incorrectly classified by the algorithm as being artifact-free (i.e., false negative).
