Role of the choroid in compensation for lens induced defocus. In a real eye (blue line), changes in choroid thickness allow rapid and accurate compensation for induced refractive error. In the absence of a choroidal response (red line), ocular compensation for defocus would be delayed by at least 1 day and would also overshoot the refractive target. From: Wallman J, Winawer J.
