“…It does so by enhancing red cell rigidity from hypoxia. The whole process is reversible (Dintenfass, 1966). As Thomas (1982) has so aptly put it "A viscous, viscious circle might be entered, with progressively slower flows favoring thrombus formation .…”

ABSTRACT:Stenosis of the internal carotid artery reduces the flow velocity in the ophthalmic artery. Lowered velocity permits increased red cell aggregation and decreased red cell deformability which increases viscosity.Contrary to the theory of remotely originating emboli, this is an alternate hypothesis regarding transient attacks of ocular and cerebral ischemia.The ophthalmic artery circulation time was measured in two groups of patients. The circulation time was defined as the interval between the appearance of contrast media in the siphon of the internal carotid artery and in the ocular choroid. The measurement was made on 151 angiograms of 108 subjects. These vessels were normal. An additional 76 patients had 108 angiograms which showed various amounts of internal carotid artery stenosis. These 76 patients had transient ischemic attacks; retinal, cerebral, or both.There is a significant difference in the ophthalmic artery circulation time in the two groups. The slowing in the ophthalmic artery is related to the degree of internal carotid artery narrowing.The circulation time in a cerebral branch of the internal carotid was not measured. It is presumed that stenosis of the internal carotid artery would have the same effect on a cerebral artery as on the ophthalmic artery.

“…Hyperviscosity is frequently thought to be rare, although its association with peripheral ischzmia is well acknowledged ( Dintenfass, 1966 ;Williams, 1968). 1 t m A I , G A N G R E N E is most frequently caused by atherosclerosis or other occlusive diseases of large arteries.…”

This report concerns 1-2 male patients who preselztcd with digital ischceinia associated With blood hyperviscosity. T h e diagnosis of hyperviscosity was anticipated in eight cases by the presence of palpable peripheral pulses, but in four other patients with diabetes naellitus or atherosclerosis obliterans, hyperviscosity was an unexpected additional finding. A wide variety oi conditions were identified as responsible f o r the blood hyperviscosity. Detection of the precise ablzorntality is importatat, since specific therapy itsay improve or correct both the condition and its related clinical rnanif estations. T h e prognosis of unrecognized hyperviscosity is poor, because of progression of the primary disease and associated ischamic coinplications. There i s also an iiacreascd likelihood of morbidity following angiography or arterial reconstructioiz.
