Distribution of each criterion of severity among the severe cases of chronic central serous chorioretinopathy
| Criteria | Frequency and specifications |
|---|---|
| Eyes with DARA, n (%) | 145 (73) |
| Mean DARA surface (DD) | 8.6 ± 4 |
| Location of DARA, n (%) | 75 (52) covering the fovea |
| 47 (32) within 1 DD of the foveaa | |
| 23 (16) outside 1 DD of the fovea | |
| Eyes with PCRD, n (%) | 69 (35) |
| Eyes with multiple hot spots, n (%) | 115 (58) |
| Mean number of hot spots (range) | 3 (2–7) |
| Location of hot spots, n (%) | 88 (75) inside the temporal vascular arcade |
| 3 (3) outside the temporal vascular arcade | |
| 26 (22) both inside and outside | |
| Eyes with diffuse leakage, n (%) | 60 (30) |
Notes:
a
DARA surface overlaps with the area as wide as 1 DD around the fovea, but does not cover the foveal depression. Data presented as mean ± SD unless otherwise indicated.
Abbreviations: DARA, diffuse atrophic retinal pigment epithelium (RPE) alterations; DD, optic disc diameters; PCRD, posterior cystoid retinal degeneration.
