Figure 3.

Relationship between age and components of the choroid determined through univariate analyses. The total choroidal area showed a borderline association with age (R = –0.18, P = 0.077) (top left). Age was significantly associated with stromal area (R = –0.30, P = 0.003) (bottom left) but exhibited no significant association with the luminal area (R = –0.10, P = 0.319) (top right), which revealed a significant association between age and the choroidal vascularity index (R = 0.36, P < 0.001) (bottom right).
