a trend toward significancep = 0.056
In 16 LB subjects, SRD thresholds showed a trend toward significance in the correlation with the age at blindness onset ( r = −0.487, p = 0.056; Figure 3B ), whereas TMD thresholds and SRTs were not correlated with the age at blindness onset ( r = 0.297, p = 0.264 and r = 0.186, and p = 0.490).
