Cumulative slow-phase eye position of the caloric nystagmus.

A coherent and stable method was implemented for constructing the cumulative slow-phase eye position of the post-caloric nystagmus. Similarity and variability analyses performed on the derived responses (inter- and intrasubject) of 6 normals confirmed the homogeneity of the measure. A pilot study on one pathological case showed marked deviation from the normal responses.
