CNFD, CNBD, CNFL, and CNBD/CNFD ratio in AutD-N, AutD-S, and AutD-M groups were compared with controls (a–d). Errors bars represent mean ± standard deviation (*P < 0.05, **P < 0.01, ***P < 0.001). PD Parkinson’s disease, AutD-N patients with no autonomic symptoms, AutD-S patients with single-domain autonomic symptoms, AutD-M patients with multiple-domain autonomic symptoms, CNFD corneal nerve fiber density, CNBD corneal nerve branch density, CNFL corneal nerve fiber length.
