BCVA and vessel density of the superficial choroidal capillaries of CSC patients.

Characteristics	Baseline	1 month	p-value (baseline vs. 1 month)	3 months	p-value (baseline vs. 3 months)
BCVA (letters)	66.05 ± 8.20	75.79 ± 4.92	<0.001*	80.13 ± 3.55	<0.001*
VDSCw (%)	49.05 ± 6.63	56.57 ± 5.83	<0.001*	56.87 ± 5.75	<0.001*
VDSCt (%)	44.18 ± 9.27	54.31 ± 9.70	<0.001*	55.19 ± 6.46	<0.001*
Vt/Vw	0.90 ± 0.16	0.96 ± 0.15	0.037*	0.97 ± 0.08	0.016*

Values are shown as the mean ± SD.

BCVA, best corrected visual acuity; CSC, central serous chorioretinopathy; VDSCw, vessel density of the superficial choroid (calculated as the percentage of pixels with a flow signal greater than the threshold); VDSRt, vessel density of the superficial choroid at the target area; Vt/Vw, ratio of the mean vessel density of the superficial choroid in the target area (area “t” in Figure 2) and the whole image (area “w” in Figure 2).

^*p < 0.05 (statistically significant difference).
