Purpose:
To evaluate the average retinal layer thicknesses in eyes with unilateral acute central serous chorioretinopathy (CSC) (with subretinal fluid (SRF)) and after complete resolution of SRF in these eyes and to compare the results with those obtained in healthy eyes.
Methods:
Fifty-four eyes of 27 patients with unilateral acute CSC (CSC in active phase) who had complete resolution of SRF and 25 eyes of 25 healthy control subjects enrolled in this retrospective study. The average thicknesses of the retinal layers were measured by segmentation analysis of optical coherence tomography at baseline and 6 months after complete resolution of SRF.
Results:
The mean outer nuclear layer (ONL) thickness was significantly lower in eyes with CSC than in fellow eyes (p < 0.001). The mean ONL thickness was increased after resolution of SRF, but still low compared to unaffected fellow eye and the increment was not statistically significant (p > 0.05). There were significant strong inverse correlations between visual acuity and ONL thicknesses at baseline and 6 months after complete resolution of SRF (p < 0.001, r = - 0.810; p < 0.001, r = - 0.705, respectively).
Conclusion:
ONL thickness was thinned in cases with acute CSC, and although there was some increment in ONL thickness 6 months after complete resolution of SRF, it was still thinner compared to unaffected fellow eyes.
