Change in SFCT and CST

Parameter	At baseline	One week after PRP	P-value* (95% CI of difference)
Horizontal SFCT (μm)	317.0	349.4	0.001 (14.5–50.2)
Vertical SFCT (μm)	319.2	350.4	0.003 (11.6–50.7)
Mean SFCT (μm)	318.1	349.9	0.001 (14.7–49.8)
CST (μm)	273.1	295.8	<0.001 (17.1–28.1)

Note that both SFCT and CST increased significantly after PRP.
SFCT, subfoveal choroidal thickness; CST, central subfield thickness; PRP, panretinal photocoagulation; CI, confidence interval.
