The difference of velocity of the eyes on caloric nystagmus, during which the inward movement of each eye is faster than the outward movement (adducent preponderance), was investigated electronystagmographically. 1) Adducent preponderance was present in both eyes, open or closed. 2) The difference of velocity of each eye was reduced by shortening the distance between the electrode, and as a result, the tendency to adducent preponderance decreased. 3) This difference was not seen in optokinetic nystagmus. 4) In one-eyed patients, adducent preponderance could be seen in the healthy eye, but some potential was also recorded on the anophthalmic side, presumably due to the interfering potential from the healthy eye, and the adducent preponderance was strenghtened. 5) Adducent preponderance with caloric nystagmus could be recognized by photo-electronystagmography without electrodes. The mechanism of adducent preponderance is discussed from the points of view of neuroanatomy and physiology.
