Objective:To investigate audio-vestibular and oculomotor functions of octogenarian. Method: Theaudition were measured with audiometry and auditory brainstem response. The semiccular, oculomotor and bal-ance functions were examinated by e lectronys tagmograp hy and posturography. Result: ①The hearing abnormalityof speech frequency were 84. 1 percent by audiometry; ②The abnormal rats of seedircular function and posturo-gram were 38. 5% and 74. 4% respectively. The body sway locus and velocity of octogenarians have increased ascompared with the group of 60 years old in the post urography; ③The latency of saccade was prolongrd and totalhearmonic distortion of pusuit was increased than that of 60 years old in the oculomotor test. Conclusion: Theeasily falling of octogenarians may be related to disturbing of sendcircular oculomotor and equilibrational functions.
