BP = blood pressure and IOP = intraocular pressure. Adapted from Liu et al., 2003 J. Ocu. Pharm. Ther⁷² and Zhang and Hargens, 2017 Physiol Rev⁷¹.

Parameter and Body Position	Equation
Mean Arterial Pressure (MAP)	Diastolic BP + (Systolic BP – Diastolic BP)/3
Adjusted MAP for Arterial Pressure at Eye (Seated)	(0.66 X MAP)
Adjusted MAP for Arterial Pressure at Eye (Supine)	(0.88 X MAP)
Adjusted MAP for Arterial Pressure at Eye (Head-Down Tilt)	MAP + 7
