Abstract
PURPOSE: To evaluate the correlation of subretinal fluid volume with choroidal thickness and macular volume in acute central serous chorioretinopathy (CSC). METHODS: Twenty patients with acute unilateral treatment-naive idiopathic CSC and 20 age-matched normal eyes were included in this prospective cross-sectional study. Subretinal fluid volume (SRFV) of study eyes was estimated using a built-in segmentation-modifying tool of Spectralis spectral-domain optic coherence tomography (SD-OCT). Subfoveal choroidal thickness (SCT) (measured with enhanced depth imaging-OCT) and macular volume (MV) were also determined. The correlation of SRFV with SCT and MV was analyzed statistically. RESULTS: There was no significant correlation of SRFV with SCT and MV in the study eyes (r=0.062, P=0.796 and r= -0.061, P=0.798, respectively). The mean SCT of the study eyes, the fellow eyes and the control eyes were 461.4±101.4, 375.3±103.7, 287.6±62.5 μm, respectively (P<0.001). The mean modified MV (determined excluding SRF volume) of the study eyes, the macular volume of the fellow and the control eyes was 8.57±0.59 mm(3), 8.75±0.4 mm(3) and 8.73±0.38 mm(3), respectively (P>0.05). CONCLUSIONS: The current study shows that subretinal fluid volume does not correlate with subfoveal choroidal thickness. This novel finding suggests that formation of subretinal fluid is not solely associated with choroidal vasculature in acute CSC.
