Drusen FAF Stages	Drusen height (μm)	Drusen width (μm)	BLamD (μm)	Drusen height +BLamD (μm)
Stage 1 (n=26)	25.1 ± 7.2	77.0 ± 33.3	4.6 ± 3.7	29.7 ± 9.5
Stage 2 (n=65)	43.9 ± 17.8	131.7 ± 61.0	7.5 ± 5.4	51.4 ± 20.0
Stage 3 (n=63)	66.7 ± 34.0	176.8 ± 90.4	12.6 ± 7.0	79.4 ± 37.4
Stage 4 (n=12)	68.5 ± 24.8	208.1 ± 80.6	6.7 ± 2.7	75.2 ± 26.3

FAF, fundus autofluorescence; BLamD, basal laminar deposit; Data are n and means ± SD. Drusen width is width at the base of drusen along the Bruch’s membrane.
