Comparison of SD-OCT and OCTA parameters between PD patients treated and not treated with dopamine agonists.

	PD-DA (32 eyes)	PD-nDA (16 eyes)
Gender (M/W)	12/4	6/2	1.000
BCVA (logMAR)	^^		0.736
Ganglion cell complex (μm)			0.457
Retinal nerve fiber layer (μm)			0.987
Subfoveal choroidal thickness (μm)			0.935
Superficial capillary plexus (%)			0.745
Deep capillary plexus (%)			0.938
Choriocapillaris (%)			0.880
Radial peripapillary capillary (%)			0.899
FAZ area (mm^2)			0.988

PD-DA: patients treated with dopamine agonists; PD-nDA: patients not treated with dopamine agonists; BCVA: best-corrected visual acuity; logMAR: logarithm of the minimum angle of resolution; FAZ: foveal avascular zone. Two-way repeated measures ANOVA. ^{^}Data are expressed as . value <0.05 was considered statistically significant.
