老年人群的动态轮廓眼压计眼压及眼脉动幅度初步调查

目的:初步了解老年人群的动态轮廓眼压计(dynamic con-tour tonometer,DCT)的眼压及眼脉动幅度(ocular pulse amplitude,OPA)分布特征。方法:对一组老年人群(88例)双眼行DCT测量,记录其眼压及OPA,对获得的数据进行分组统计学分析比较。结果:受试者总体平均DCT眼压为16.57±2.87mmHg,总体平均OPA为2.37±0.83mmHg。受试者的右眼、左眼DCT平均眼压分别为16.91±2.03mmHg及16.24±3.08mmHg,双眼之间无显著统计学差异(P=0.007)。左右眼的OPA分别为2.37±0.83mmHg及2.38±0.82mmHg,双眼之间无显著统计学差异(P=0.907)。将受试者按性别分组比较均无显著统计学差异。双眼DCT眼压值的高度与OPA的大小之间无显著相关关系(右眼:r=0.206,P=0.054;左眼:r=0.121,P=0.262)。结论:初步获得DCT眼压及OPA在老年人群中的分布特征,了解到不同性别、不同眼别之间的DCT眼压及OPA无显著统计学差异,为今后DCT临床研究奠定了一定的基础。

Investigation of intraocular pressure and ocular pulse amplitude measured by dynamic contour tonometer in old population

AIM: To investigate the features of intraocular pres-sure (IOP) and ocular pulse amplitude (OPA) measured by dynamic contour tonometer (DCT) in old population. ·METHODS: The binocular IOP and OPA of 88 cases were measured by DCT. The results were statistically analyzed. ·RESULTS: The average IOP and OPA were 16.57±2.87mmHg and 2.37±0.83mmHg in all. The IOP of the right eye and left eye were 16.91±2.03mmHg and 16.24±3.08mmHg, respectively. There was no statistically significant difference (P=0.007). The OPA of the right eye and left eye were 2.37±0.83mmHg and 2.38±0.82mmHg respectively, with no statistically significant difference (P=0.907). No statistically significant correlation between the IOP and OPA were detected (right eye: r=0.206, P=0.054; left eye: r=0.121, P=0.262).·CONCLUSION: We know the features of IOP and OPA measured by DCT in old population, which lays the foundations for further study.
