早中期老年帕金森病患者眼球运动异常的临床研究

摘要

Objective To study ocular motor function in patients with Parkinson disease.Methods Videonystagmography(VNG)was used for testing ocular saccade and smooth pursuit eye movement(SPEM)in 14 patients with idiopathic Parkinson disease and 10 age and sex-matched control subjects to compare the latency of saccades,the accuracy of saeeades and SPEMGain between two groups. Results The latency of saceades was found to be much more increased in PD group (291.23±46.25)ms than that in healthy group(244.45±23.11)ms(P＜0.05);and the accuracy of saccades was found to be decreased in PD group(87.98±6.1 6)as compared to that in healthy group (95.21±8.56)(P＜0.05).PD group was found to have more decreased SPEM gain(0.81±0.12)than that in healthy group(0.90±0.1 5)(P＜0.05). Conclusions The findings suggest that ocular motor function is abnormal in Parkinson disease patients.%目的 研究帕金森病患者的眼球运动功能情况,并探讨其临床意义.方法 利用视频眼震电图(VNG)对14名原发性帕金森病患者(PD)和10名年龄、性别相匹配的健康人行眼球扫视运动、平稳追踪运动(SPEM)测试,比较两组间扫视潜伏期、扫视精确度和平稳追踪增益值(SPEMGain)的差异.结果 PD组眼球扫视运动的潜伏期(291.23±46.25)ms,较对照组的(244.45±23.11)ms显著延长.P＜0.05;扫视精确度87.98±6.1 6,较对照组的95.21±8.56显著下降,P＜0.05;PD组SPEMGain 0.81±0.12,也明显低于对照组的0.90±0.15,P＜0.05.结论 帕金森病患者眼球运动功能有明显异常.
