Figure 4

Retinal nerve fibre layer thickness at baseline for patients with disease onset of ≤6, 6–12 and >12 months (A). The mean retinal nerve fibre layer thickness for the temporal, superior, nasal and inferior retinal quadrants are shown. Relative change from baseline to Weeks 4, 12 and 24 in retinal nerve fibre layer thickness (B). n = 6/4 (idebenone/placebo) for eyes with disease onset of ≤6 months; n = 8/6 for eyes with disease onset of 6–12 months; n = 32/26 for eyes with disease onset of >12 months. Filled squares/solid line = idebenone group; filled circles/dashed line = placebo group. RNFLT = retinal nerve fibre layer thickness.
