[Interaction between vision and vestibular nystagmus].
In order to assess the visuo-vestibular interaction and its behaviour in connection with the age, we have submitted 20 healthy subjects from two age groups ranging between 21-30 and 65-75 years of age to two rotation tests (with closed eyes and with opened eyes with fixation of a light). The results show a variation of the nystagmic response with fixation of about 60% in the young people and of about 40% in the elderly. These results demonstrate that the extent of the inhibition is dependent upon age and is less effective in the elderly.
