摘　　要：【目的】探讨影响近视患者眼脉冲振幅的可能因素。【方法】采用动态轮廓眼压计(DCT)测量75名近视患者眼脉冲振幅(OPA),同时记录患者的年龄、性别、屈光度、舒张压(DP)、收缩压(SP)、脉压(PP)、眼压(IOP),采用SPSS11.5统计分析软件处理检测数据,得出相关系数及回归方程。【结果】OPA与SE、IOP、PP呈显著相关性,其相关系数分别为(0.173、0.222、0.218,P=0.035、0.007、0.008),与舒张压呈显著负相关,相关系数为-0.197,P=0.016,与收缩压、年龄及性格不相关,其相关系数为(-0.044、-0.067、-0.080,P=0.598、0.416、0.333)。回归方程(OPA=1.215+0.122IOP+0.073SE+0.027PP-0.020DP)。【结论】近视眼脉冲振幅与眼压、平均球镜当量、脉压呈正相关,与舒张压呈负相关。[Objective] To investigate the possible factors influencing ocular pulse amplitude（OPA） for patients with myopia. [Methods] Dynamic contour tonometry（DCT） was applied to measure OPA for 75 patients with myopia. Meanwhile age, gender, spherical equivalent （SE）, diastolic pressure（DP）, systolic pressure （SP）, pulse pressure（PP） and intraocular pressure（IOP） were recorded. After these data were manipulated with SPSSll, 5 software, correlation coefficient and regression equation were obtained. [Results] OPA had obvious positive correlation with SE, IOP and PP（r=0. 173, P =0. 035; r=0. 222, P =0. 007; r=0. 218, P =0. 008） respectively, and had obvious negative correlation with DP（r= -0. 197, P =0. 016）. Besides, OPA had no correlation with SP, age and gender（r=-0. 044, P =0. 598; r=-0. 067, P =0. 416; r=-0. 080, P =0.333）. Regression equation was as follows： OPA=1. 215＋0.122IOP＋0.073SE＋0.027PP-0.020DP. [Conclusion] OPA for myopia had positive correlation with IOP, SE, PP and negative correlation with DP.
