Abstract
AIM: To investigate the correlation between macular morphology and visual acuity and visual deformation in acute central serous chorioretinopathy(CSC). <p>METHODS: A cross-sectional clinical case-control study was conducted in which 38 patients with acute monocular CSC(CSC group)and 38 normal eyes(control group)were included. The best corrected visual acuity(BCVA), slit lamp microscope, indirect ophthalmoscope, frequency domain optical coherence tomography(OCT), color fundus photography and M-charts were performed in all subjects. The BCVA was converted to the minimum resolution angle LogMAR record when doing statistical. The mean LogMAR, macular retinal thickness(CFT), subretinal fluid thickness(SRF), transverse diameter length of subretinal fluid in macular area and visual deformation(M value)were significantly different between the two groups. The correlation between CFT and SRF, transverse diameter length of subretinal fluid in macular area and M value was analyzed. <p>RESULTS: The mean BCVA in acute CSC group was 0.15±0.15(LogMAR), that in control group was 0.12±0.12(LogMAR); CFT was 418.89 ±134.74μm in CSC group and SRF was 286.95±136.77μm in CSC group. The length of subretinal fluid transverse diameter in macular area was 2926.37±1109.66μm. CFT in control group was 217.58±12.49μm, SRF was 0, and the transverse diameter of subretinal fluid in macular area was 0. The M value of CSC group was 0.86±0.40, MH and MV were 0.99±0.38, 0.73±0.43, respectively. Compared with MV, MH was obviously aggravated, the difference was statistically significant(<i>t</i>=4.564, <i>P</i><0.01). There was no correlation between BCVA and the degree of visual deformation in CSC group(<i>r</i>=-0.124,<i> P</i>>0.05). In CSC group, BCVA had no correlation with SRF or the length of subretinal fluid transverse diameter in macular area(<i>r</i>=-0.059, -0.12; <i>P</i>=0.73, 0.48; respectively.)There was a positive correlation between CFT and M value in CSC group(<i>r</i>=0.91, <i>P</i><0.01). The value of MV was positively correlated with the length of transverse diameter of subretinal fluid in macular area(<i>r</i>=0.934, <i>P</i><0.01), and the value of MH was positively correlated with SRF(<i>r</i>=0.949,<i> P</i><0.01). <p>CONCLUSION: In acute CSC group, BCVA had no correlation with CFT, SRF, macular subretinal fluid transverse length and visual deformability, and visual deformability was positively correlated with CFT, SRF and macular subretinal fluid transverse length; MV was positively correlated with subretinal fluid transverse length, and MH was positively correlated with SRF.
