Different electroretinography response amplitudes of groups with or without macular involvement. (A) Mean log amplitudes of rod response were 0.413 and 0.440 in group without and with macular involvement, respectively. (B) Mean log amplitudes of rod-cone response were 0.478 and 0.629 in group without and with macular involvement, respectively. (C) Mean log amplitudes of cone responses were 0.538 and 0.541 in group without and with macular involvement, respectively. (D) Mean log amplitudes of 30 Hz flicker were 0.897 and 0.818 in group without and with macular involvement, respectively.*p < 0.05; **p < 0.01 using unpaired t-test.
