Fig. 2

The inner and outer boundaries of the CC slab were adjusted relative to the RPE fit reference to generate three different axial positions; 11–21 μm (A), 21–31 μm (B) and 31–41 μm (C) from the RPE band centreline. OCT angiography (OCTA) en face 6 × 6 mm slabs of choriocapillaris (CC) (2) and corresponding structural en face slabs (3) exported from three different slab locations were used to generate a compensated CC image (4) that was the used to generate a binarized image (5) to calculate the CC flow deficit percentage.
