Binocular fundus reflectometry and ophthalmodynamometry in carotid occlusion.
Continuous bilateral simultaneous measurement of the circulation time between arm and ocular fundus and arm and earlobe was performed by fundus reflectometry (FRM). Differences in dye appearance time between the two ocular fundi were larger in cases of angiographically proved stenosis or occlusion of the common or the internal carotid artery. Prolonged dye appearance times in the earlobe were observed in occlusive disease of the common or external carotid artery. The harmless method of FRM seems to be useful in the detection of carotid occlusive disease and helpful in deciding whether carotid angiography should be performed.
