Figure 7. Correlation between whole visual field or spared hemifield at baseline and widening after prismatic adaptation. Upper panels: whole visual field extent at baseline. A: T30 (r= -0. 69, p=0.03); B: U30 (r= -0. 68, p=0.05). Lower panels: spared visual field extent at baseline. C: T30 (r= -0. 72, p=0.03); D: U30 (r= -0. 73, p=0.03). Abscissa: visual field extent at baseline (cm2), ordinate: visual field widening after 3 weeks of adaptation. It can be noticed that the wider is the visual field at the baseline, the smaller the improvement after adaptation
