Inverted caloric nystagmus by warm air stimulation.
The rather frequent appearance of an inverted nystagmus, when stimulating with warm air for caloric testing, is emphasized. It is clearly demonstrated that this nystagmus is a real caloric one, but beating in the opposed direction. Its occurrence in many cases, especially when an active middle ear pathology is present, diminishes the reliability of this air stimulation technique, as it is especially indicated in these cases.
