Abstrakt: Carotid artery stenosis can be evaluated noninvasively by ocular pneumoplethysmography (OPG-Gee). This simultaneously measures both ophthalmic artery pressures and is therefore capable of detecting pressure-reducing or hemodynamically significant carotid lesions. An OPG-angiography correlation was made for 200 carotid arteries in 110 patients. Sensitivity, specificity and overall accuracy were 91%, 89%, and 90% respectively, if calculated per artery. On a per patient basis these figures were 94%, 88%, and 91%. Applications of this rapid and simple technique in clinical practice include selection of patients for angiography and carotid endarterectomy, as well as early and late control of the operative results.
