Meniere's disease in Uppsala and Osaka. A comparative study.

A total of 100 patients with Meniere's disease, 50 at the University Hospital of Uppsala and 50 at the Osaka City University Hospital, were submitted to a test battery using the same methods, and the results obtained at the two hospitals were compared. Briefly the findings were as follows. There was no significant difference in age at examination or in the duration of illness. No significant difference was detected with regard to a) the average hearing loss or the types of audiogram, b) the incidence of spontaneous or positional nystagmus, or c) caloric and optokinetic test results. A linear correlation was found between caloric responses and pure tone audiograms in both the Uppsala and Osaka patients.
