Fig. 2: Comparison of the retinal parameters between the Parkinson’s disease (PD) and healthy controls groups.
From: The macular inner plexiform layer thickness as an early diagnostic indicator for Parkinson’s disease
a The average and temporal quadrant pRNFL thicknesses were significantly lower in the PD group than in the HCs group. b Patients with PD had a thicker OPL and thinner mRNFL, GCL, IPL, INL, and ONL. The error bars the indicate standard deviation of PD or HCs. HCs healthy controls, PD Parkinson’s disease, pRNFL peripapillary retinal nerve fiber layer, mRNFL macular retinal nerve fiber layer, GCL ganglion cell layer, IPL inner plexiform layer, INL inner nuclear layer, OPL outer plexiform layer, ONL outer nuclear layer, IS/OS inner segment/outer segment, OPR photoreceptor outer segment/retinal pigment epithelium, RPE retinal pigment epithelium.
