Notes: *Significantly thinner choroid in the refractive group compared to the emmetropic group (p < 0.05) with adjustment for multiple comparisons (Bonferroni). †Significantly thinner choroid in the high myopic refractive group compared to the myopic group (p < 0.05) with adjustment for multiple comparisons (Bonferroni).
