Values are mean (SD).
Contralateral and ipsilateral differences in peak 1 to peak 2 amplitudes are expressed as an asymmetry ratio (AR) calculated as AR% = 100×(contra–ipsi)/(contra+ipsi).
Statistical difference of the ipsilateral eye response to the corresponding value of the contralateral eye: *p<0.05; **p<0.01.
Contra, contralateral; ipsi, ipsilateral.
