Statistical significance was tested using analysis of variance, and the Bonferroni method was used for post hoc tests. Statistical significance was defined as p<0.05 (two tailed).
Group 0—without myopic maculopathy; group 1—tessellated fundus; group 2—diffuse chorioretinal atrophy.
For post hoc tests, superscript a refers to significant difference between group 0 and group 1 (P<0.05), superscript b refers to significant difference between group 0 and group 2 (P<0.05), and superscript c refers to significant difference between group 1 and group 2 (P<0.05)
