Aniseikonia after reduced-fluence photodynamic therapy in patients with central serous chorioretinopathy

Abstract This study investigated aniseikonia after reduced-fluence photodynamic therapy (RFPDT) for central serous chorioretinopathy (CSC). We examined 48 eyes of 48 patients (38 men; mean age, 49.2 ± 9.9 years) with CSC resolved after RFPDT. Horizontal and vertical aniseikonia were measured using the New Aniseikonia Test at baseline, 6 months, and 12 months after RFPDT. The maximum absolute value of the horizontal and vertical measurements indicated the aniseikonia score. The aniseikonia score was 2.2 ± 2.3 at 6 months and 2.2 ± 2.0 at 12 months after RFPDT, both of which improved significantly from the baseline score of 4.1 ± 2.9 (P
