  1. * Early disease definition No.1: lesion size <2 disk area, baseline VA study eye ≥ 20/80 Snellen, no scar or atrophy.
  2. Early disease definition No.2: occult and better VA at baseline in fellow eye (worse in study eye).
  3. LogMAR = logarithm of the minimum angle of resolution; NV-AMD = neovascular age-related macular degeneration; SD = standard deviation; VA = visual acuity.
