Between SD OCT and TD OCT , mean thickness of the retina was = 567 m , SRF was = 1.535 m , and subretinal tissue complex was = 586 m. Thickness measurements were reproducible for retina ( ICC = 0.84 ; 95 % CI , 0.83-0 .86 ) , SRF ( ICC = 0.88 ; 95 % CI , 0.86-0 .89 ) , and subretinal tissue complex ( ICC = 0.91 ; 95 % CI , 0.89-0 .92 ) , with 25-m difference in these measurements in 71 % , 94 % , and 61 % of paired scans , respectively .
