Corneal confocal microscopy parameters in postural instability/gait disturbance vs tremor dominant patients with Parkinson’s disease.

CCM parameter PIGD (n = 25) TD (n = 42) p value
CNFD (no/mm2) 25.33 ± 1.49 22.57 ± 1.02 0.12
CNBD (no/mm2) 27.57 ± 3.27 23.33 ± 1.64 0.20
CNFL (mm/mm2) 14.54 ± 0.75 13.39 ± 0.48 0.18
CTBD (no/mm2) 38.51 ± 4.65 34.51 ± 2.16 0.93

Data shown as mean ± SEM. CCM: corneal confocal microscopy, PIGD: postural instability/gait disturbance, TD: tremor dominant, CNFD: corneal nerve fibre density, CNBD: corneal nerve branch density, CNFL: corneal nerve fibre length, CTBD: corneal total branch density.
