Treatment results in patients with CSC treated by PDT
| Patient No | Fluorescein angiographic features at follow up | ICG-A features at follow up | Size of laser spot applied (ICG-A guided) | Diameter of the largest anterior choroidal vessel before PDT | Diameter of the same choroidal vessel 3 months after PDT | Changes in diameter of the choroidal vessels at 3 months |
|---|---|---|---|---|---|---|
| PED = detachment of the retinal pigment epithelium; RPE = retinal pigment epithelium; CNV = choroidal neovascularisation. | ||||||
| 1 | No leakage at 1 month, resolution of the PED, ring of RPE atrophy | Narrowing of the choroidal vessels, absence of choroidal leakage, PED resolved | 3800 μm | 622 μm | 338 μm | −46% |
| 2 | No leakage at 1 month, development of a juxtafoveal CNV at 3 months | Narrowing of the choroidal vessels, absence of choroidal leakage | 2600 μm | 545 μm | 442 μm | −19% |
| 3 | No leakage at 1 month, focal RPE window defect | Narrowing of the choroidal vessels, absence of choroidal leakage | 3000 μm | 571 μm | 428 μm | −25% |
| 4 | No leakage at 3 months, diffuse RPE atrophy | Narrowing of the choroidal vessels, decreased choroidal leakage | 2800 μm | 605 μm | 382 μm | −37% |
| 5 | No leakage at 1 month, diffuse RPE atrophy | Narrowing of the choroidal vessels, absence of choroidal leakage | 3000 μm | 470 μm | 300 μm | −36% |
| 6 | No leakage at 1 month, diffuse RPE atrophy | Narrowing of the choroidal vessels, decreased choroidal leakage | 3200 μm | 465 μm | 338 μm | −27% |
