Images are from the right eye of a 70-year-old man with central serous chorioretinopathy with superotemporal macular drainage vortex veins. (A) Widefield choroidal thickness map shows thickened choroid at the posterior pole area as well as in the superotemporal and superonasal areas. (B) Three months after half-fluence photodynamic therapy (PDT), widefield choroidal thickness map shows a reduction in choroidal thickening. (C) Subtracted wide-field choroidal thickness map shows the area of diminished choroidal thickness. (D) Horizontal B-mode optical coherence tomography (OCT) through the fovea shows choroidal thickening associated with dilated outer choroidal vessels accompanied by subretinal fluid. The central choroidal thickness is 432 µm. (E) Three months after half-fluence PDT, horizontal B-mode OCT through the fovea shows diminished choroidal thickening with no subretinal fluid. The central choroidal thickness is 292 µm. (F) Pre-treatment widefield en face OCT image of the choroid shows superotemporal macular drainage vortex veins. Anastomoses can be seen between the superotemporal and superonasal vortex veins superior to the papilla. (G) Superimposed image of the pre-treatment widefield en face OCT and the subtracted widefield choroidal thickness map reveals that choroidal thickness decreased mainly in the macular area and the region corresponding to the superotemporal macular drainage vortex veins. The nasal area of diminished choroidal thickness overlaps the superonasal vortex vein distribution.
