Jumbling:With special reference to Meyer zum Gottesberge's test

概要

論文の詳細を見る
Jumbling is a symptom of disorders in visual perception (oscillopsia and/or blurred vision) when a patient with loss of vestibular function moves about too abruptly. A 38 year-old male with this disorder due to severe bilateral vestibular neuronitis is described. The phenomenon was satisfactorily quantified by a modification of the Meyer zum Gottesberge's head-shaking test. The test-maneuver was as follows: binocular visual acuity was examined while the patient shook his head two or three thimes per second ten to twenty degrees horizontally or vertically, and the results were compared with his visual acuity when his head was still. A diagnosis of jumbling was made when the visual acuity during head-shaking was less than half the visual acuity when the head was motionless. In the present case, the test was also very useful in monitoring recovery from jumbling.
