Figure 3. HVF parameters in patients with and without mutations in OPA1. A, B: Humphrey visual field (HVF) mean deviation values averaged oculus uterque (OU) as a function of age (A) and plotted oculus dexter (OD) and oculus sinister (OS) on the X- and Y-axes, respectively (B). C, D: HVF pattern standard deviation values averaged OU as a function of age (C) and plotted OD and OS on the X- and Y-axes, respectively (D).
