ICC: intra-class correlation coefficient; CI: confidence interval; TCA-1.5: total choroidal area measured for the choroidal area under a 1.5 mm horizontal line centered on the fovea; TCA-3: total choroidal area measured for the choroidal area under a 3 mm horizontal line centered on the fovea; TCA-6: total choroidal area measured for the choroidal area under a 6 mm horizontal line centered on the fovea; LA-1.5: luminal area measured for the choroidal area under a 1.5 mm horizontal line centered on the fovea; LA-3: luminal area measured for the choroidal area under a 3 mm horizontal line centered on the fovea; LA-6: luminal area measured for the choroidal area under a 6 mm horizontal line centered on the fovea.
