Receiver operating characteristic (ROC) curves of the choroidal vascularity index (CVI) and the subfoveal choroidal thickness (SFCT) parameters to discriminate eyes with MG from control eyes with PACG.

|---|---|---|---|---|---|---|---|
| CVI (%) | 0.911 | 0.859–0.963 | <0.001 | <63.60 | 96.23 | 73.33 | 0.034 |
| SFCT (μm) | 0.840 | 0.769–0.912 | <0.001 | >431 | 71.70 | 85.00 |
p*: Pairwise comparison of the ROC curves of the SFCT and CVI in the MedCalc software (version 15.2.2).
Cutoff point: the maximum value at the Youden's index (sensitivity + specificity – 1).
In bold: significant at p < 0.05.
