Figure 3

Electroretinogram depicting the rod- and cone-driven responses of the right eyes of two related males affected by XLRS (c.52G>A) and from a representative normal control subject. The rod-driven b-wave is relatively preserved in the 13-y/o III.4, but the 45-y/o-uncle II.2 shows remarkable reduction of b-wave amplitude, with the typical XLRS electronegative ERG waveform. The cone-mediated responses are overall normal in the young III.4 male, but are delayed and reduced in amplitude in the middle-aged II.2.
