【摘要】 目的：探讨视动中枢试验对老年眩晕患者的诊断价值。方法：利用眼震电图仪，对70例60岁以上眩晕患者及25例健康老人进行眼震电图各项检测，并对视动中枢部分进行定量分析。结果：健康老人组各项均正常，周围性病变组除4例视跟踪试验为Ⅲ型外，其余正常。中枢病变组　扫视试验12例异常(44.4％)，视跟踪试验Ⅲ～Ⅳ型17例(63.0％)，视动性眼震异常为81.5％，三组的扫视试验、视跟踪试验及视动试验结果有显著性差异(P＜0.01)；进一步定量分析左右二向所诱发视动眼震的频率、平均振幅和慢相速度之差值差异有显著性(P＜0.05)。结论：视动中枢试验对中枢病变的诊断阳性率较高，可作为鉴别老年人外周性和中枢性眩晕的依据。更多还原

【Abstract】 Objective: To study the diagnostic value of the oculomotor center test in the elderly patients with vertigo. Methods: 70 elders over 60 years old with vertigo and 25 other healthy elders had been tested with electronystagrnography. The quantitative analysis of the oculomotor center test had been made in all patients. Results: All the tests were normal in the healthy group and in the group with peripheral vertigo except 4 patients showed type Ⅲ in the eye tracking test. In the group of central vertigo, 12 patients (44.4%) presented abnormality in the ocular saccade test; 17 patients had type Ⅲ～Ⅳ in the eye tracking test (63.0%); the abnormal rate of optokinetic nystagmus was 81.5%.There was significant difference in the test of ocular saccade, eye tracking and optokinetic nystagmus between the three groups (P<0.01). Further quantitative analysis showed that differences of frequncy, equal amplitude of vibration and nystagmus slow phase velocity of the eye to the right and left in optokinetic nystagmus of three groups had significance (P<0.05). Conclusion:Oculomotor center test had high diagnostic value in the central vertigo and could be used as a differential index between the peripheral and central vertigo.更多还原
