Figure 3. Change in Minimum Rim Width and Total Retinal Thickness .

The change in minimum rim width (A) and global total retinal thickness (B) is compared with before spaceflight (preflight) for both eyes of each participant (circles). The open circles represent data collected before and after spaceflight in the 6-month cohort; gray circles, data collected during spaceflight in the 6-month cohort; blue circles, data collected from participant 1; orange circles, data collected from participant 2; and circles with a superimposed cross, an eye that had optic disc edema findings.
