TABLE 2.

Age, vision status, and reading performance of the young normal (YN), older normal (ON), non-macular (Non-Mac) and macular (Mac) groups (mean [standard deviation]).

Groups	Age (years)	VA (logMAR)	CS (log unit)	Maximum reading speed (wpm)	Critical print size (logMAR)	Reading acuity (logMAR)
YN*	20.5 [3.6]	−0.09 [0.11]	2.13 [0.07]	2.20 [0.06]	0.21 [0.10]	−0.14 [0.07]
ON	68.0 [5.0]	0.00 [0.11]	2.02 [0.11]	2.17 [0.05]	0.26 [0.12]	−0.05 [0.10]
Non-Mac	56.7 [16.1]	0.82 [0.40]	0.96 [0.52]	2.06 [0.16]	1.35 [0.82]	0.71 [0.41]
Mac	72.9 [16.7]	0.64 [0.31]	1.16 [0.33]	2.07 [0.21]	1.49 [0.90]	0.71 [0.40]

*For the YN group, the listed VA, CS and reading indices were under baseline condition with no filtering.
