Abstract

BackgroundWe evaluated subfoveal choroidal thickness measured with two different forms of optical coherence tomography OCT, enhanced-depth imaging EDI and swept-source SS OCT, in central serous chorioretinopathy CSC.

MethodsFifty-six eyes of 48 patients diagnosed with acute or chronic CSC, were studied prospectively. Subfoveal choroidal thickness was measured as the distance between the outer border of the retinal pigment epithelium-Bruch’s membrane complex, and the chorioscleral border under the fovea. Subfoveal choroidal thickness was measured using EDI-OCT and SS-OCT. We also measured serous retinal detachment SRD only with SS-OCT. The Pearson correlation coefficient was used to assess the correlation between subfoveal choroidal thickness values determined by the two different OCT modalities.

ResultsThe mean patient age was 52 ± 13 years range, 32–82 years. Among the 56 eyes, 21 had acute CSC and 35 had chronic CSC. Subfoveal choroidal thickness measured with EDI-OCT was 336.6 ± 91.6 μm in acute and 388.0 ± 103.4 μm in chronic CSC. With SS-OCT, the thickness in acute CSC was 332.0 ± 96.7 μm and that in chronic CSC was 392.6 ± 101.3 μm. Acute CSC p <0.001, correlation coefficient; r = 0.99 and chronic CSC p <0.001, correlation coefficient; r = 0.97 values obtained with the two different OCT modalities correlated significantly. Among the 56 eyes, 43 19 eyes with acute and 24 with chronic CSC were evaluable for SRD height by SS-OCT. The mean SRD height was 128.9 ± 83.6 μm in acute cases and 96.3 ± 62.0 μm in chronic cases.

ConclusionsSubfoveal choroidal thickness obtained with two different OCT modalities correlated significantly.
