Different electroretinography response amplitudes of different subtypes of retinitis pigmentosa. (A) Mean log amplitudes of rod response were 0.246, 0.567, and 0.675 in typical, pericentral and other type, respectively. (B) Mean log amplitudes of rod-cone response were 0.283, 0.776, and 0.895 in typical, pericentral and other type, respectively. (C) Mean log amplitudes of cone response were 0.300, 0.671, and 1.035 in typical, pericentral and other type, respectively. (D) Mean log amplitudes of 30 Hz flicker were 0.766, 0.919, and 1.000 in typical, pericentral and other type, respectively. *p < 0.05; **p < 0.01 using analysis of variance followed by application of a Sidak test.
