Correlations at Baseline between Flow Deficit Parameters and Annual Square Root Enlargement Rate of Geographic Atrophy in the Different Areas around the Geographic Atrophy (r = Pearson)

Region of Interest	Percentage FDs	Average FD Area mm²

Rim 1 (1 degree: 0–300 μm out)	r = 0.403 P = 0.063	r = 0.544 P = 0.009
Rim 2 (from 301 to 600 μm out)	r = 0.498 P = 0.018	r = 0.677 P < 0.001
Rim 3 (Total scan area minus GA+R1+R2)	r = 0.496 P = 0.019	r = 0.690 P < 0.001
Total scan area minus GA	r = 0.626 P = 0.002	r = 0.747 P < 0.001

FD = flow deficit; GA = geographic atrophy; R1 = Region 1; R2 = Region 2.
