Figure 1

Vision plotted as a function of age among patients with PRPF31-associated retinitis pigmentosa. Visual acuity (A) and visual field diameter (deg2) (B) are plotted for every patient visit for each eye individually. Visual acuity has been converted to decimal notation. Lower normal is 11,399 deg2 for visual field area with a V4e light stimulus. 30-Hz flicker ERG amplitudes (C) by age among patients with PRPF31-associated retinitis pigmentosa. The 30-Hz (cone) amplitudes are plotted for every patient visit for each eye individually. The solid horizontal line represents the lower limit of normal for 30-Hz amplitude (50 μV) and the dashed horizontal line represents half the lower limit of normal (25 μV).
