AMD |
Age-related macular degeneration |
Drusen size >63 µm are considered as an sign of AMD and suggest an increased risk of progressing
to large drusen and late AMD.
|
| 2 |
dAMD |
Dry AMD |
Presence and size of drusen (>63 µm) and potential retinal pigment epithelium (RPE)
abnormalities without neovascular and geographic atrophy.
|

wAMD/nAMD |
Wet AMD/Neovascular AMD |
Neovascular AMD was defined by ophthalmoscopic and fluorescein angiographic findings of classic
or occult choroidal neovascular membranes, serous or hemorrhagic RPE detachments, and
fibrovascular disciform scar in reference to the International Classification of Age-Related
Maculopathy and Macular Degeneration.

GA |
Geographic atrophy |
Geographic atrophy (GA) was defined as an area of retinal pigment epithelial depigmentation
occurring in the macula (defined as a 3000‑micron diameter circle centered at the fovea) within
which underlying choroidal blood vessels are usually visualized.
|
| 5 |
Early_AMD |
Early age-related macular degeneration |
Early AMD was defined as the presence of a large drusen (soft distinct or soft indistinct drusen
with a diameter > 125 lm) and/or retinal pigment epithelium (RPE) abnormalities
(hyperpigmentation or hypopigmentation) within the grid, in the absence of late AMD.
|
| 6 |
Late/Advanced AMD |
GA+exudative AMD |
Late AMD was defined as the presence of exudative AMD or geographic atrophy (GA). Exudative AMD
was defined as RPE detachment or serous detachment of the sensory retina, subretinal, or sub-RPE
hemorrhages, and subretinal fibrous scars. Geographic atrophy was defined as sharply edged,
roughly round or oval areas of RPE hypopigmentation, with clearly visible choroidal vessels.
|
| 7 |
PCV |
polypoidal choroidal vasculopathy |
PCV was defined as clusters of polypoidal dilation of the vessels with or without abnormal
vascular networks in the superficial choroid in ICGA and irregularly elevated RPE line in OCT
images.
