This case illustrates that timely PDT treatment soon after onset could prevent damage to foveal ONL (Figure 7).

This case demonstrates that in patients with longer disease duration, even after successful treatment, structural damage to the ONL remains irreversible (Figure 8).

This case demonstrates that in patients with duration>1 and <=3 months, ONL thickness could still recover after PDT (Figure 9).
