Mapping of baseline performance across the blind-field border. A, Example of locations tested during the mapping process, superimposed on the baseline Humphrey composite map of SA participant CB009. The gray scale denotes luminance detection sensitivity (dB), and the red line denotes the blind-field border. Red circles, locations with Static-Ori performance ≥72.5% correct; gray circles, locations with Static-Ori performance <72.5% correct; dashed gray circles, locations selected for training. Mapping across the border of the blind field moved horizontally from intact to deeper blind-field locations. Once a training location was selected, performance was also measured at mirror-symmetric, intact-field locations (red circles in left hemifield). B, Example of Static-Ori mapping across the blind-field border of a CH participant (CB020). Labeling conventions as in A. C, Plot of CS for Static-Ori in subacute participants at first locations fully inside the blind-field border (1st blind field), selected training locations (Training), and corresponding, intact-field locations. Each data point represents a single location. Box plots indicate the median (line within the box), 25–75% quartile range (box), and 10–90% range (whiskers). Five SA participants had measurable CS (i.e., CS > 1) at seven different first blind-field locations, averaging a CS of 3.5 ± 2.1 at these locations. D, Plot of baseline CS in chronic participants at first locations inside the blind-field border, selected training locations, and corresponding, intact-field locations. Each data point represents a single location. Five CH participants had measurable CS at six different first blind-field locations, with an average CS of 4.2 ± 3.2 at these locations. Labeling convention as in C. E, Percent correct performance on the Static-Ori task for 100% contrast stimuli measured in subacute participants. Four of the 13 subacute participants attained >72.5% correct at seven different first blind-field locations. Labeling conventions as in C and D. F, Percent correct performance at 100% contrast on the Static-Ori task in chronic participants. Five of the 12 chronic participants attained >72.5% correct at six different first blind-field locations. Labeling conventions as in C and D.
