Refraction, AL, ChT, and ChBP in the FDM+VC and FDM+QUI groups. Comparison of the interocular differences in (A) refraction and (B) AL at the beginning (0 W) and end (2 W) of the treatment period. Comparison of (C) ChT and (D) ChBP at the end of 2 weeks of treatment. W, weeks; Fellow, eyes contralateral to the FDM eyes and not subjected to either vitamin C or quinpirole injections; Treated, FDM eyes subjected to either vitamin C or quinpirole injections; VC, vitamin C; QUI, quinpirole. *P < 0.05, **P < 0.01, and ***P < 0.001, repeated-measures ANOVA with Bonferroni correction.
