Table 3. Additional tomographic characteristics of the choroid in each disease group.
| Group | Vessel Dilation | Convolution | Scleral invisibility | Hyper-thickening | Hyper-thinning |
|---|---|---|---|---|---|
| Normal (N = 30) | 4 (13.3%) | 0 (0.0%) | 0 (0.0%) | 3 (10.0%) | 5 (16.7%) |
| CSC (N = 30) | 23 (76.7%)* | 0 (0.0%) | 3 (10.0%) | 11 (36.7%) | 1 (3.3%) |
| PCV (N = 30) | 11 (36.7%) | 1 (3.3%) | 1 (3.3%) | 4 (13.3%) | 9 (30.0%) |
| VKH (N = 27) | 5 (18.5%) | 11 (40.7%)* | 19 (70.4%)* | 3 (11.1%) | 0 (0.0%) |
CSC, central serous chorioretinopathy; PCV, polypoidal choroidal vasculopathy; VKH, Vogt-Koyanagi-Harada disease.
* Indicates the frequency of tomographic characteristics 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 0.002 were considered to indicate statistical significance.
