AB  - BACKGROUND/AIMS: Choroidal thickness measurements are reported to differ between 
      spectral-domain optical coherence tomography (SD-OCT) and swept-source OCT 
      (SS-OCT). The aim of this study was to assess the comparability of choroidal 
      thickness measurements using SS-OCT and SD-OCT devices among normal participants. 
      MATERIALS AND METHODS: This was a prospective study of 31 (62 eyes) normal 
      participants. Choroidal imaging was performed sequentially with the Spectralis 
      OCT (SD-OCT) and the deep range imaging OCT (DRI OCT-1) (SS-OCT) using 
      standardized imaging protocols. The subfoveal choroidal thickness (SFChT) was 
      measured manually by two masked retinal specialists. Paired t-tests and 
      intraclass correlation coefficients (ICCs) were used to compare the measurements. 
      RESULTS: The mean SFChT was 319.5 mum and 325.3 mum for DRI OCT-1 and Spectralis 
      OCT, respectively (P = 0.001), with a mean difference of 5.9 with ICC of 0.97. 
      The mean difference in choroidal thickness between the OCT devices was larger 
      among eyes with choroidal thickness > 350 mum compared with eyes with thinner 
      choroids (8.0 mum vs. 4.7 mum). CONCLUSIONS: SFChT measurements are comparable 
      between DRI OCT-1 and Spectralis OCT. The variability between the devices 
      increases in thicker choroids.
