  • 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).

  • 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).

  • Group 0—without myopic maculopathy; group 1—tessellated fundus; group 2—diffuse chorioretinal atrophy.

  • Centre, central fovea; ChT, choroidal thickness; ETDRS, Early Treatment Diabetic Retinopathy Study; I, inferior; In, inner circle of the ETDRS grid; N, nasal; Out, outer circle of the ETDRS grid; RT, retinal thickness; S, superior; T, temporal.
