Figure 4. Biometric measurements in
defocus-only, vehicle-defocus, and APO-defocus (0.025 to 250
ng/μl) groups before and at 11 days of hyperopic defocus. A:
Refraction; B: Vitreous length; C: Axial length.
At the concentrations examined, APO has no statistically
significant effect on the development of defocus-induced myopia.
