Representative drawings of control and PD retinal fields. Each color defines an individual mRGC. a Melanopsin plexus in a control wholemount retina. b Melanopsin plexus in a PD wholemount retina. c Total mRGC quantification (number of mRGCs per mm2) and comparison between control and PD subjects. d Comparison of the mRGC density per cell type in control and PD subjects. Scale bar, 100 μm. Data is presented as mean ± s.d. *P < 0.05, **P < 0.01
