AUC_CoST (Area under CoST curve) has unit of mm-msec. AUC_ORA (Area under the ORA curve) has unit of a.u.-msec. a_i and b_i root mean square (RMS) has unit of mm for CoST. a_i and b_i root mean square (RMS) has unit of a.u. for CoST. IOP_g (ORA Goldmann correlated intraocular pressure), IOP_cc (ORA Corneal compensated intraocular pressure), CH (Corneal hysteresis) and CRF (Corneal resistance factor) have unit of mmHg. Deformation amplitude (DA) is in mm.
