  1. Data are presented as mean ± SD (standard deviation) and median (interquartile range).
  2. AMD: age-related macular degeneration; EZ: ellipsoid zone; FD%: percentage of flow deficits.
  3. aIndependent samples T test—comparison with controls.
  4. bIndependent samples Mann–Whitney U test—comparison with controls.
