Figure 3 (A) Average relative monocular latency of the more affected eye (poorer MD) as a function of the mean deviation of that eye is shown for individual eyes (symbols) of the control (+), NTG (open square), and HTG (solid square) groups. The box plot shows the 25%/75% range (box), the 5%/95% range (vertical line) and the mean of the normative group (horizontal bar). Its placement along the x axis is arbitrary. (B) As in (A) for the average interocular latency difference.
