Noninvasive techniques for evaluating peripheral vascular and extracranial cerebrovascular diseases.
Five hundred and fifty-eight patients have been evaluated at the peripheral vascularocular pulse blood flow laboratory over a year. The accurate correlations with angiography in the peripheral arterial investigation has been 100%, the cerebrovascular investigation has been 75% and the venous correlation has been 86 2/3%. Even though the results from ocular testing are slightly lower than reported by Kartchner and McRae, we believe that the results emphasize the delicacy of instrumentation and the degree of refinement necessary in reading of the tests. We do think, however, that a 75% accuracy does indicate this method to be of significant benefit as a noninvasive stroke screening procedure.
