The human axial length and choroidal thickness responses to continuous and alternating episodes of myopic and hyperopic blur
Fig 5
The mean change in axial length from baseline (0 minute time point) during 15 minute alternating cycles of hyperopic then myopic defocus (Condition E), and myopic then hyperopic defocus (Condition F) for all subjects.
Vertical error bars represent the standard error of the mean difference in axial length, and horizontal error bars represent the standard error in measurement time. Asterisks indicate a significant mean difference from the baseline axial length (p < 0.05).
