OCTA parameters of macular area.

Macular	Single	MIA	Denoise		value
PSNR				344.50	<0.0001
Foveal				9.22	0.0035
Superior				63.89	<0.0001
Nasal				25.52	<0.0001
Inferior				21.80	<0.0001
Temporal				18.40	<0.0001

Notes: repeated-measure ANOVA was used to compare the differences in the PSNR and VD. Abbreviations: OCTA: optical coherence tomography angiography; ANOVA: analysis of variance; PSNR: peak signal-to-noise ratio; MIA: multiple image averaging; VD: vessel density.
