Comparison of measurement from three imaging modalities

488-FAF 450-FAF 450-RF
Mean absolute inter-reader difference (mm2) 0.46 2.01 0.25
CR (mm2) 1.35 8.13 1.08
CV 1.11 2.05 0.92
ICC 0.994 0.711 0.997
GA area (mm2), median (IQR) 2.1 (0.8–6.4) 1.0 (0.3–4.3) 2.6 (0.8–6.8)

CR, 95% coefficient of repeatability; CV, coefficient of variation; FAF, fundus autofluorescence; GA, geographic atrophy; ICC, intraclass correlation coefficient; 450-FAF, FAF with the 450 nm wavelength excitation light; 450-RF, image obtained from the elaboration of the ‘colour’ 450-FAF; 488-FAF, FAF with the 488 nm wavelength excitation light.
