METHODS: This was a single-center, prospective, observational, cross-sectional study with consecutive inclusion of 33 healthy subjects and 43 T2D patients. Subjects underwent three consecutive swept-source optical coherence tomography scans in a single session. After automatic delineation of the choroid, subfoveal choroidal thickness, and thickness at 500-µm intervals up to 2, 500 µm nasal and temporal from the fovea were measured using the software caliper by the same operator. Intraclass correlation coefficients (ICCs), coefficients of variation, and test-retest variability were calculated.
RESULTS: Mean subfoveal choroidal thickness in healthy subjects and in T2D patients was 229.97 ± 79.9 and 192.67 ± 74.3 µm, respectively (P = 0.013). All intrasession intraclass correlation coefficients were higher than 0.95 and 0.99, respectively. Coefficients of variations were less than 4.4% and 1.8%, respectively. Test-retest variability ranged from 0.76 µm to 11.12 µm and 0.64 µm to 6.29 µm, respectively. No significant differences were found in the intrasession repeatability of any choroidal measurement between healthy subjects and T2D patients.
CONCLUSION: Swept-source optical coherence tomography provided excellent intrasession repeatability of choroidal thickness measurements in healthy subjects and T2D patients.
