Oculo-cardiac reflex in patients with Meniere's disease

Abstract

We analyzed the bilateral oculo-cardiac reflex in patients with Meniere's disease and evaluated their parasympathetic nervous function. Although the oculo-cardiac responses of patients with Meniere's disease were not different from those of healthy controls, the incidence of difference in laterality of each eye response was significantly increased in the patients. In addition, the patients with Meniere's disease exhibited weaker oculo-cardiac responses of the affec-ted side than on the unaffected side. These findings suggest asymmetry of parasympathetic nervous function in patients with Meniere's disease.
