Screening for significant carotid stenosis by ocular pneumoplethysmography.
Carotid stenosis is significant when the resulting lumen is 50 per cent or less of the diameter of the vessel distal to the carotid sinus. The ocular pneumoplethysmograph can detect these stenoses with an accuracy of 97 per cent.
