Figure 7.

Cartoon diagrams illustrating the relationship between the RPE and choroidal vessels. Each row in the diagrams represents a different visit, with the top row representing the baseline assessment and the middle and bottom rows representing two follow-up visits. In the region with RPE atrophy, the outer choroidal vessels may decrease in size compared with the baseline assessment (top row) in the follow-up assessments (middle and bottom rows). This reduction may also extend to the border region if this area transitions into GA during the follow-up period (bottom row).
