Ocular dysmetria is seldom mentioned in the neurootologic literature as an electronystagmographic (ENG) abnormality. For the last two years, we found ocular dysmetria on 38 cases out of 1,879 ENG recordings. Cerebellar dysfunction was the most apparent cause in 13 out of 21 cases examined by us. The group of unilateral hypermetria showed some other ENG abnormalities like positional nystagmus, post-caloric directional preponderance, failure of fixation suppression of post-caloric nystagmus (FFS), more scattered distribution of quick phase amplitudes of post-caloric and optokinetic nystagmus on the side of hypermetria. We wonder whether this symptomatology, or at least part of it, is due to dysfunction of the flocculo-nodular lobe of the cerrebellum.
