N, nasal; T, temporal; S, superior; I, inferior; LA, Luminal area; SA, Stromal area; TCA, total choroidal area. The linear regression was performed by GEEs. For the association between choroidal parameters and age, sex has been adjusted. For the association between choroidal parameters and sex, age has been adjusted. For the association between choroidal parameters and axial length, age and sex have been adjusted.

Significance of difference.
