Overall, the effect of visual condition (EC/ EO) was highly significant ( F = 55.6, p < 0.0001), whereas there were no significant interactions between (a) subjects group (PSP, IPD, CTR) and visual condition (EC/EO, F = 0.63, p = 0.53), and (b) segment, subject group, and visual condition ( F = 0.54, p = 0.70, Figures 3b , c , g , h , m , n ).
