title: [The investigation of the audio-vestibular and oculomotor functions in people more than eighty years old].
abstract: OBJECTIVE
  To investigate audio-vestibular and oculomotor functions of octogenarian.
  
  
  METHODS
  The audition were measured with audiometry and auditory brainstem response. The semicrcular, oculomotor and balance functions were examinated by electronystagmography and posturography.
  
  
  RESULTS
  1. The hearing abnormality of speech frequency were 84.1 percent by audiometry; 2. The abnormal rats of semicircular function and posturogram were 38.5% and 74.4% respectively. The body sway locus and velocity of octogenarians have increased as compared with the group of 60 years old in the posturography; 3. The latency of saccade was prolonged and total hearmonic distortion of pusuit was increased than that of 60 years old in the oculomotor test.
  
  
  CONCLUSIONS
  The easily falling of octogenarians may be related to disturbing of semicircular oculomotor and equilibrational functions.
