The statistical efficacy of three indirect techniques for noninvasive diagnosis of carotid artery disease was assessed in a prospective, blind study of 103 persons. Oculoplethysmography-carotid phonoangiography, periorbital Doppler examination and supraorbital photoplethysmography were acceptably sensitive only to carotid artery occlusions and preocclusive carotid artery stenoses exceeding a 75 per cent diameter reduction. Less pronounced lesions could not be reliably detected by any of the techniques used either singly or in combination. Supraorbital photoplethysmography proved inferior to the other methods because of its poor specificity rate.
在一项针对103人的前瞻性盲法研究中，评估了三种用于无创诊断颈动脉疾病的间接技术的统计学效能。眼体积描记法-颈动脉血管音图检查、眶周多普勒检查和眶上光体积描记法仅对颈动脉闭塞以及直径缩小超过75%的闭塞前颈动脉狭窄具有可接受的敏感性。单独或联合使用的任何一种技术都无法可靠地检测出不太明显的病变。眶上光体积描记法因其特异性率低而被证明不如其他方法。
