iAMD intermediate age-related macular degeneration, GA geographic atrophy, MNV macular neovascularization, FAF fundus autofluorescence, SDD subretinal drusenoid deposits, sqrt square root, HRF hyperreflective foci.
aThese eyes were not gradable due to insufficient image quality.
bDue to the low frequency the single eye was not considered in the statistical model.
cThese eyes were not gradable due to insufficient image quality or the absence of a predominant FAF pattern.
dThese eyes were graded inconclusive as the coalescence of the individual lobules was only partial.
