Figure 4

Relative changes in choroidal thickness (ΔX-ΔN) in response to positive and negative lens defocus at 0.67 “chick lux” and 0.2 “chick lux”. There were signed choroidal changes in white and red light. Choroidal changes in red light were comparable to those in white light for positive and negative defocus. There were no choroidal changes in blue light or in 0.2 “lux” white light. The choroidal changes in white and red light were both significantly greater than those in blue. Symbols are as in Figure 3.
