Table 2. Tomographic classification of the choroid in each disease group.
| Group | S type | DA type | D type | M type | PV type | P-value* |
|---|---|---|---|---|---|---|
| Normal (N = 30) | 26 (86.7%) | 1 (3.3%) | 0 (0%) | 0 (0%) | 3 (10.0%) | |
| CSC (N = 30) | 13 (43.3%)† | 16 (53.3%)† | 0 (0%) | 0 (0%) | 1 (3.3%) | <0.001 |
| PCV (N = 30) | 14 (46.7%)† | 10 (33.3%) | 1 (3.3%) | 0 (0%) | 5 (16.7%) | 0.002 |
| VKH (N = 27) | 3 (11.1%)† | 1 (3.7%) | 17 (63.0%)† | 6 (22.2%) | 0 (0%) | <0.001 |
CSC, central serous chorioretinopathy; PCV, polypoidal choroidal vasculopathy; VKH, Vogt-Koyanagi-Harada disease.
* P-value indicates intergroup differences in the distribution of tomographic types between normal controls and each disease group. P-values less than 0.017 (accounting for a Bonferroni correction) were considered significant.
† Indicates the frequency of tomographic types which have P-values less than 0.003 when compared with normal controls using Fischer’s exact test. Accounting for a Bonferroni correction, P-values less than 0.003 were considered to indicate statistical significance.
