Choroidal thickness reductions in superotemporal and inferotemporal areas with or without macular drainage vortex veins 3 months after half-fluence photodynamic therapy for central serous chorioretinopathy. Reductions in choroidal thickness in the superotemporal and inferotemporal areas with macular drainage vortex veins were significantly greater than those in the superotemporal or inferotemporal areas without such vortex veins.
