Rate of change in CCT before treatment after 1/2PDT and 1/3PDT in patients with CSC. The rate of change in CCT was evaluated before treatment and 2 weeks, and 1, 3, and 6 months after 1/2PDT and 1/3PDT in patients with CSC. The solid line indicates the 1/2PDT group, and the dashed line indicates the 1/3PDT group. The error bars represent the standard deviations of the participants. * p < 0.05 (Dunnett test). The asterisk represents significant differences between the 1/2PDT and 1/3PDT groups. * p < 0.05 (Steel test). 1/2PDT: half-dose verteporfin photodynamic therapy, 1/3PDT: one-third dose verteporfin photodynamic therapy, CSC: central serous chorioretinopathy, CCT: central choroid thickness
