CNFD (a), CNBD (b) and CNFL (c) in each group were compared with controls and dot plots were generated. CCM parameters in controls, PD patients and SP group (a–c). Errors bars represent mean ± standard deviation (*P < 0.05, **P < 0.01, ***P < 0.001). PD Parkinson’s disease, SP secondary parkinsonism, CCM corneal confocal microscopy, CNFD corneal nerve fiber density, CNBD corneal nerve branch density, CNFL corneal nerve fiber length.
