Medscape reported that, at a meeting of the American Neurological Association, researchers using a bedside eye exam showed how they were able to outperform magnetic resonance imaging (MRI) and flag 100% of strokes.
In their prospective cross-sectional study, investigators examined 101 patients at high risk for acute vesticular syndrome. The researchers administered 3 tests checking vestibule-ocular-reflex on horizontal head impulse, nystagmus, and ocular alignment during prism cross-cover. All patients underwent neuroimaging. The researchers only misclassified 1 out of 25 patients who had a vestibular disease that was a benign condition of the inner ear, while 12% of patients who had a stroke identified on a later MRI had an initially false-negative result.
