Typical traces of aortic and maxillary artery (max A) pressures. First CRA pulsation (diastolic ODP) was seen when IOP was elevated to a level equal to aortic and maxillary diastolic pressure. Complete CRA closure (systolic ODP) was seen when IOP was elevated to a level above maxillary artery but below aortic systolic pressure.
