A, emmetropia; B, low-to-moderate myopia; C, high myopia, DVD, deep vessel density. Numbers appear as mean ± standard deviation for normally distributed variable. Normally distributed data were analyzed by one-way ANOVA and nonnormal data analysis by the Kruskal–Wallis test. ∗ANOVA was applied. P values that are significant are in bold and italicized.
