　　目的调查80岁以上老人的听力、前庭及视动功能变化。方法用纯音测听及听性脑干反应测试听力功能；用眼震电图及姿势图测试半规管、视动及平衡功能。结果(1)语频听力异常者点84.1%；(2)半规管功能和平衡功能异常者分别为38.5％和74.4％，与60岁组比较，重心晃动的轨迹长，速度大；(3)视动功能检查，80岁以上老人扫视潜伏期延长，跟踪失真度加大。结论随着年龄老化，80岁以上老人半规管、视动、平衡功能，均有不同程度减退，可能是老年人易摔倒的重要原因。

Objective: To investigate audio-vestibular and oculomotor functions of octogenarian. Metbod: The audition were measured with audiometry and auditory beainstem response. The semicrcular, oculomotor and balance functions were examinated by electronystagmography and posturography, Result: (1)The bearing abnormality of speech frequency were 84. 1 percent by audionetry;(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. Conclusion: The easily fal ing of octogenarians may be related to disturbing of seminircular oculomotor and equilibrational functions.
