青光眼的眼压及眼脉动幅度比较分析

目的:观察比较慢性闭角型青光眼、原发性开角型青光眼、正常眼压性青光眼以及正常人的眼压,眼脉动幅度特征及其相关性。方法:收集临床确诊为慢性闭角型青光眼患者19例,原发性开角型青光眼18例,正常眼压性青光眼15例,正常人20例,用动态轮廓眼压计测量其眼压及眼脉动幅度,同时测量患者的血压及心率。运用SPSS14.0进行统计学分析。结果:慢性闭角型青光眼组的平均眼压为25.42±9.95mmHg,OPA为3.84±0.88mmHg;原发性开角型青光眼组的平均眼压为23.12±5.47mmHg,OPA为3.29±0.90mmHg;正常眼压性青光眼组的平均眼压为16.52±2.23mmHg,OPA为1.85±0.47mmHg;正常人组的平均眼压为16.31±2.67mmHg,OPA为2.47±0.80mmHg。前两组与后两组之间的眼压存在着显著性差异,四组之间的OPA均存在统计学差异。四组患者的眼压及眼脉动幅度之间存在着弱相关性,但无统计学意义。结论:慢性闭角型青光眼、原发性开角型青光眼及正常眼压性青光眼的OPA之间存在统计学差异,眼压与OPA之间存在弱相关性,但无统计学意义。

Correlation between IOP and OPA in glaucoma

AIM:To investigate the feature of intraocular pressure(IOP) and ocular pulse amplitude(OPA) measured by dynamic contour tonometer(DCT) in the chronic angle-closure glaucoma(CACG),the primary angle-open glaucoma(PAOG),the normal tension glaucoma(NTG) and the healthy controls and to analyze the relation between the IOP and OPA.METHODS:Nineteen cases of chronic angle-closure glaucoma,18 cases of primary angle-open glaucoma,15 cases of normal tension glaucoma and 20 cases of healthy controls were taken into the...
