Figure 7.

Changes in the interocular differences (treated eye – control eye) in sub-foveal choroidal thickness (red symbols) and refractive error (white symbols) plotted as a function of age for individual DL-LIH monkeys. The dashed line in each panel represents zero interocular difference in the changes of refractive error and choroidal thickness. Analogous to that in the DL-LIM monkeys, choroidal thickness development in DL-LIH monkeys was appropriate for the direction of refractive changes (i.e., monkeys that did not successfully compensate for imposed myopic defocus exhibited relative choroidal thinning instead of thickening), at least in the early- and mid-stages of the lens-rearing period. Note that, unlike Figure 6 which illustrate the same association using averaged data, data of the DL-LIH group were presented individually because of the inter-subject variability in the direction of refractive changes the group averages were not representative of individual animals and obscured the association between refraction and choroidal thickness.
