SD: standard deviation; IOP: intraocular pressure; D: diopter; CCT: central corneal thickness; SBP: systolic blood pressure; DBP: diastolic blood pressure; OPP: ocular perfusion pressure BPM: beats per minute; BMI: body mass index
1, 2: Calculated as the differential pressure between diastolic or systolic blood pressure and IOP.
3: Calculated as the differential pressure between mean BP and IOP (mean BP: DBP+1/3*(SBP -DBP)).
