A variety of noninvasive tests are available for the evaluation of patients with suspected extracranial cerebrovascular disease. Recent emphasis on more sophisticated techniques has raised questions concerning the current utility of older methods, e.g., pulse delay oculoplethysmography (OPG) and supraorbital Doppler (SOD) examination. The results of OPG and SOD examination were compared with the findings of carotid arteriography in 75 consecutive patients. This analysis revealed a sensitivity of 78 per cent, specificity of 92 per cent, false-positive rate of 12.5 per cent, false-negative rate of 15.8 per cent, and overall diagnostic accuracy of 85 per cent for OPG. Although the specificity of SOD was superior (94.3%), the sensitivity (41%) false-positive rate (16.6%), false-negative rate (30.5%), and overall diagnostic accuracy of 71.6 per cent of SOD revealed it to be an inferior test of significant carotid stenosis. Based on its ease of performance, minimum of time required, and high level of diagnostic accuracy, OPG currently remains a valuable screening procedure for carotid disease, particularly in the asymptomatic bruit population.
有多种非侵入性检查可用于评估疑似颅外脑血管疾病的患者。最近对更复杂技术的重视引发了关于旧方法（如脉搏延迟眼体积描记法（OPG）和眶上多普勒（SOD）检查）当前效用的问题。对75例连续患者的OPG和SOD检查结果与颈动脉血管造影结果进行了比较。该分析显示，OPG的敏感性为78%，特异性为92%，假阳性率为12.5%，假阴性率为15.8%，总体诊断准确率为85%。虽然SOD的特异性更高（94.3%），但其敏感性（41%）、假阳性率（16.6%）、假阴性率（30.5%）以及71.6%的总体诊断准确率表明它是对显著颈动脉狭窄的较差检查。基于其操作简便、所需时间最少以及诊断准确率高，OPG目前仍然是颈动脉疾病的一种有价值的筛查方法，特别是在无症状杂音人群中。
