摘　　要：【目的】探讨球周麻醉对眼压(intraocularpressure,IOP)以及眼脉动振幅(ocularpulseamplitude,OPA)的影响。【方法】随机选择单眼白内障患者32例,患眼施行球周麻醉,另眼设为对照。分别于球周麻醉前以及麻醉后3min、10min采用动态轮廓眼压计(dynamiccontourtonometer,DCT)测量注射眼和对照眼的IOP及OPA值,单因素方差分析麻醉前后IOP和OPA的变化。【结果】注射利多卡因后注射眼和对照眼的眼压均无明显变化。注射眼OPA值显著降低,而对照眼在注射后3minOPA值升高,10min后恢复至注射前水平。【结论】球周麻醉可导致OPA降低,而对眼压无影响。[Objective]To evaluate the effect of peribulbar anesthesia on intraocular pressure（IOP） and ocular pulse amplitude（OPA）in the injected eye and the non-injected eye. [Methods]Thirty two consecutive adult patients with monocular cataract enrolled in this study, IOP and OPA were measured with dynamic contour tonometer（DCT） before and 3 minutes and 10 minutes after administration of lidocaine anesthesia. Data was analyzed with software SPSS 11.5. [Results]The IOP remained stable in the injected and the non-injected eyes after administration of lidocaine anesthesia. The OPA was significantly decreased after injection of the anesthesia agent in the injected eyes. The OPA in the non-injected eyes increased significantly 3 minutes after injection of the anesthesia agent, returning to preinjection level 10 minutes after the injection. [Conclusion]Peribulbar anesthesia leads to decrease of OPA and shows no effect on IOP in the iniected eyes.
