  1. IOP intraocular pressure, SE spherical equivalent, D diopter, AL axial length, ChT choroidal thickness, N number.
  2. aData were presented as mean ± standard deviation unless otherwise indicated.
  3. *Statistical significance was tested using Chi-Square tests.
  4. †Statistical significance was tested using one-way ANOVA. The Bonferroni method was used for post hoc tests and the results showed that all pairwise comparisons except for BMI between the myopia and emmetropia groups, as well as IOP between the myopia and emmetropia groups and between the myopia and hyperopia groups, were statistically significant.
