The linear artifact was found in 122 cases (81.88%). All the detected linear artifact was located stably at a depth of 485 μm beneath the RPE. The subfoveal choroidal thickness measured with EDI-OCT was 325.43 ± 140.98 μm in these subjects (Table 2).Table 2Ophthalmologic data (mean ± SD) of study participants.APACGPACSCPACGPOAGCSCControlFrequency of artifact, n (%)12 (52%)18 (75%)23 (72%)24 (96%)25 (100%)25 (100%)Subfoveal choroidal thickness (μm)319.39 ± 134.96348.38 ± 145.15336.00 ± 115.03283.88 ± 91.36495.00 ± 113.82240.35 ± 106.32Depth of the artifact (μm)485485485485485485Height from ellipsoid zone to RPE/Bruch’s complex (μm)79.83 ± 6.4283.41 ± 6.0482.17 ± 5.9182.33 ± 5.1477.00 ± 7.0778.60 ± 4.54Height of the artifact (μm)61.50 ± 6.2664.61 ± 5.5664.13 ± 6.5063.46 ± 4.8562.00 ± 7.0762.25 ± 4.71Foveal retinal thickness (μm)213.35 ± 14.90213.25 ± 13.36214.72 ± 13.26217.68 ± 14.98485.84 ± 151.15208.85 ± 14.51
