SD-OCT and OCTA parameters in PD patients and controls.

	PD (48 eyes)	Controls (50 eyes)
BCVA (logMAR)	^^		0.484
Ganglion cell complex (μm)			0.002
Retinal nerve fiber layer (μm)			0.010
Subfoveal choroidal thickness (μm)			0.988
Superficial capillary plexus (%)			0.002
Deep capillary plexus (%)			0.878
Choriocapillaris (%)			0.517
Radial peripapillary capillary (%)			0.002
FAZ area (mm^2)			<0.001

Two-way repeated measures ANOVA. ^{^}Data expressed as . value <0.05 was considered statistically significant. BCVA: best-corrected visual acuity; logMAR: logarithm of the minimum angle of resolution. FAZ: foveal avascular zone. Significant values are in bold.
