Images are from the left eye of a 66-year-old man with central serous chorioretinopathy with inferotemporal macular drainage vortex veins. (A) Widefield choroidal thickness map shows thickened choroid at the posterior pole area and in the inferotemporal areas. (B) Three months after half-fluence photodynamic therapy (PDT), widefield choroidal thickness map shows a reduction in choroidal thickening. (C) Subtracted widefield 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 316 µm. (E) Three months after half-fluence PDT, horizontal B-mode OCT through the fovea shows reduced choroidal thickening with no subretinal fluid. The central choroidal thickness is 221 µm. (F) Pre-treatment widefield en face OCT image of the choroid shows inferotemporal macular drainage vortex veins. There are no anastomoses between the inferotemporal and nasal vortex veins. (G) Superimposed image of the pre-treatment widefield en face OCT and the subtracted widefield choroidal thickness map reveals choroidal thickness to have decreased mainly in the macular area and the region corresponding to the inferotemporal macular drainage vortex veins.
