Doppler Manometry
Using an appropriate blood pressure cuff sized for our patients attached to a sphygomomanometer, the blood flow of a limb is occluded similar to how your blood pressure is taken. As the pressure is slowly released from the cuff and the blood flows back into the vessels, an ultrasound doppler probe placed over the artery lower than the cuff picks up the first blood rushing back into the vessels. This point is recorded as the systolic blood pressure and we make our determinations of systemic hypertension based on clinical ophthalmic examination and this number.
