Diabetic nonperfusion status and foveal avascular zone area on FA and OCTA.

	OCTA (mm^2)		FA (mm^2)		value
	FAZ area		FAZ area
	Mean	SD	Mean	SD
With DMI ()	0.5851	0.3539	0.6850	0.5318	0.1374
Without DMI ()	0.2069	0.7990	0.1973	0.6787	0.9594

OCTA: optical coherence tomography angiography; FA: fluorescein angiography; FAZ: foveal avascular area; SD: standard deviation; DMI: diabetic macular ischemia. value: calculated using nonparametric Wilcoxon signed-rank test.
