Changes in the mean CFT and BCVA according to the treatment modality. The red, green, orange, and blue lines represent the patient subgroups treated with PDT and IVB; PDT, steroid, and IVB; PDT and IVR; and PDT alone, respectively. For the multiple comparison, repeated measures ANOVA was used to compare the pattern of changes in the mean values of the CFT and BCVA at baseline, and then 1 day, 1 week and 1 month after treatment, according to the treatment modality. a The pattern of change in the CFT over time was similar among the treatment modalities (P = 0.974, repeated measures ANOVA). b The pattern of change in the BCVA over time was also similar among the treatment modalities (P = 0.247, repeated measures ANOVA). BCVA, best-corrected visual acuity; CFT, central foveal thickness; IVB, intravitreal injection of bevacizumab; IVR, intravitreal injection of ranibizumab; logMAR, logarithm of the minimum angle of resolution; PDT, photodynamic therapy
