Abstract
In this study we performed standardized measurements of spontaneous nystagmus (SN), caloric tests and velocity step tests on a well-defined group of 92 Meniere patients as part of a diagnostic protocol. The aim of the study was to look for results that could contribute to the diagnosis, but more specifically to a possible classification, of Meniere's disease. Relations with average hearing loss, shape of the audiogram, average hearing loss, duration and severity of perceived symptoms of disease and differences between uni-and bilateral Meniere's disease were studied. Directional preponderance (DP) in unilaterally affected patients and labyrinthine preponderance (LP) in both uni- and bilaterally affected patients were significantly more often directed towards the unaffected (uni) or least affected (bi) side (p = 0.007, p = 0.001, p = 0.002, respectively). DP was correlated with LP (uni: R = 0.615, p <0.001; bi: R = 0.438, p <0.01), which means that the DP can be seen as a latent SN, directed to the unaffected side. With the caloric test parameters LP and DP it was possible to find unilateral weakness. In unilateral disease a duration of disease
