“…In a recent paper, 8 we compared systolic OAP values determined by the OMD with simultaneously recorded direct systolic internal carotid artery pressure and indirect systolic BAP in healthy subjects; OAP correlates highly with ipsilateral intra-arterial internal carotid artery pressure (r=0.95, «=10) and with BAP (r=0.85, «=40). The mean ophthalmic pressure index (Figure 2) in both control groups (OAP vs. carotid pressure and OAP vs. BAP ratio) were almost identical (0.69 vs. 0.68).…”

“…The instrument and the theoretical basis of the measurement procedure have been described in detail elsewhere. 8 Briefly, the OMD device consists of a chamber, one side of which has an opening adaptable to the orbital borders. The opposite side is closed and equipped with a Doppler transducer and an inlet pipe for compressed air connected to a manometer.…”

“…7 Based on Doppler ultrasound principles, OMD provides simultaneous information about both the maximum perfusion pressure and the flow direction in the ophthalmic circulation. In a previous paper, 8 we validated this new OAP measurement technique and presented baseline data from normal subjects.The purpose of our present study is to describe the findings of Doppler OAP and flow direction measurements in a series of patients with angiographically documented occlusive carotid artery disease of known severity, to analyze their hemodynamic disturbances, and to compare these results with normal data obtained previously in healthy subjects. …”

1 -3 Unfortunately, the circle of Willis is subject to considerable morphologic variation and differs among individuals in its functional efficiency. 4As the ophthalmic artery is the first large branch of the internal carotid artery, the study of the ophthalmic artery pressure (OAP) provides information about the amount of distal internal carotid artery blood pressure.1 ' 3 -5 Furthermore, examination of the ophthalmic artery flow direction in patients with occlusive carotid artery disease may help to detect the sources of collateral pathways. 6 We recently developed a simple and safe method Received August 15, 1988; accepted February 1, 1989. for OAP determination, called ophthalmomanometryDoppler (OMD). 7 Based on Doppler ultrasound principles, OMD provides simultaneous information about both the maximum perfusion pressure and the flow direction in the ophthalmic circulation. In a previous paper, 8 we validated this new OAP measurement technique and presented baseline data from normal subjects.The purpose of our present study is to describe the findings of Doppler OAP and flow direction measurements in a series of patients with angiographically documented occlusive carotid artery disease of known severity, to analyze their hemodynamic disturbances, and to compare these results with normal data obtained previously in healthy subjects. Subjects and MethodsWe selected 102 patients (85 men and 17 women) aged 37-74 (mean 59) years who had undergone both bilateral OAP determination by OMD and subsequent carotid angiography. To be included in the study, the patients had to present 60-100% diameter obstruction of the carotid arteries proxiby guest on May 11, 2018 http://stroke.ahajournals.org/ Downloaded from
