| DA type | <0.001† | 0.006 | 0.192 |
| D type | <0.001† | <0.001† | 1.000 |
| M type | 0.008 | 0.008 | NA |
| PV type | 1.000 | 0.053 | 0.195 |
| Vessel dilation | <0.001† | 0.151 | 0.004 |

| Scleral Invisibility | <0.001† | <0.001† | 0.612 |
| Hyperthickening | 0.033 | 1.000 | 0.072 |

CSC, central serous chorioretinopathy; PCV, polypoidal choroidal vasculopathy; VKH, Vogt-Koyanagi-Harada disease.
* Accounting for Bonferroni correction, P-values less than 0.008 were considered significant.
† As for the inter-group comparison of the distribution of choroid types or tomographic characteristcs, P-values less than 0.0017 were considered significant.
