Figure 2

Flowchart showing patient inclusion. One patient of “lost to follow-up” could not come at a given moment, because the patient was admitted to a hospital for a general disease. Two patients of “protocol deviations” presented unanalyzable OCT imaging slices due to involuntary eye movement during the follow-up period.
