Foveal ONL thickness increased in resolved CSC eyes compared with thickness in their active phase (a-f). a and b. The horizontal and vertical line scans of a 48-year-old male patient with best corrected visual acuity (BCVA) of 20/25 and symptom duration of 42 days before half-dose photodynamic therapy (PDT). Ratio of the retinal detachment height to the subretinal space width was 0.176 on the horizontal scan and 0.187 on the vertical scan. c. The vertical line scan of the eye 12 months after half-dose PDT showing complete resolution of the subretinal fluid. The difference between the foveal ONL thickness12m after half-dose PDT and that before half-dose PDT was 18 μm. d and e. The horizontal and vertical line scans of a 55-year-old female patient with BCVA of 20/40 and symptom duration of 176 days before half-dose PDT. Ratio of the retinal detachment height to the subretinal space width on the horizontal scan was 0.094 and that on the vertical scan was 0.117. f. The horizontal line scan of the eye 12 months after half-dose PDT showing complete resolution of the subretinal fluid. The difference between the foveal ONL thickness 12 m after half-dose PDT and that before half-dose PDT was 4 μm
