To determine the accuracy of ocular pneumoplethysmography (OPG-Gee) in detecting carotid arterial occlusive disease, 350 patients were tested by OPG-Gee. Sixty-three patients underwent angiography and the findings were correlated with the results of OPG-Gee tracings. Testing without carotid compression averaged three minutes and was easily performed by a physician or technician. There were no significant complications. Hypertension did not affect evaluation. There were two false-negative tests and no false-positive tests. Without carotid compression the overall accuracy for testing for significant arterial stenosis was 97%. When a carotid compression test was added, the two missed lesions were detected.
为确定眼体积描记法（OPG-Gee）检测颈动脉闭塞性疾病的准确性，对350例患者进行了OPG-Gee检测。63例患者接受了血管造影，其结果与OPG-Gee描记结果相关。不进行颈动脉压迫的检测平均持续3分钟，医生或技术人员均可轻松操作。未出现显著并发症。高血压不影响评估结果。有2例假阴性检测，无假阳性检测。不进行颈动脉压迫时，检测显著动脉狭窄的总体准确率为97%。增加颈动脉压迫试验后，检测出了2例漏诊病变。
