Change over time in all the average perfusion density and retinal sensitivities measured in the affected temporal area. (A) Change in perfusion density. Compared to 1 and 6 months, there was a significant decrease at 12 months (B) Change in retinal sensitivity. Compared to baseline, there was a significant improvement at 6 and 12 months. The bars show the mean ± standard error of the mean (n = 119–136 in each group). **P < 0.01, ***P < 0.001, ****P < 0.0001, one-way analysis of variance with Tukey’s post hoc test.
