Abstract

CONTEXT

In attempt to find an alternative way to determine conversion from ocular hypertension to primary open angle glaucoma (POAG) (besides visual field and optic disc changes), we analyzed intraocular pressure (IOP) pulse wave in spectral domain.

AIMS

The aim of this study was to test the potential differences in spectral content of IOP pulse wave between ocular hypertension and POAG patients, which could indicate conversion.

SETTINGS AND DESIGN

Cross-sectional study designed to test the differences in the spectral content of pressure pulse wave between nontreated ocular hypertensive and nontreated, freshly diagnosed POAG patients.

METHODS

The total of 40 eyes of 40 subjects was included: 20 previously untreated ocular hypertensive patients, and 20 previously untreated POAG patients. Continuous IOP measuring gained by dynamic contour tonometry was submitted to fast Fourier transform signal analysis and further statistical data processing. Statistics Analysis Used: Ocular and systemic characteristics of the tested subjects were compared by analysis of variance appropriate for this study design. A P < 0.05 was considered to be statistically significant.

RESULTS

Higher spectral components of the IOP pulse wave was discerned up to the fifth harmonic in both of the tested groups. No statistically significant differences were found in any of the tested harmonic amplitudes.

CONCLUSIONS

There are no differences in the spectral content of IOP pulse wave between ocular hypertensive and primary open angle glaucoma patients which could be indicative for conversion.

摘要

背景

为了寻找一种确定从高眼压症转变为原发性开角型青光眼（POAG）的替代方法（除视野和视盘变化外），我们分析了频谱域中的眼内压（IOP）脉搏波。

目的

本研究的目的是测试高眼压症患者和POAG患者之间IOP脉搏波频谱成分的潜在差异，这可能表明病情转变。

设置与设计

横断面研究，旨在测试未经治疗的高眼压症患者和未经治疗的新诊断POAG患者之间压力脉搏波频谱成分的差异。

方法

纳入40名受试者的40只眼睛：20名先前未经治疗的高眼压症患者和20名先前未经治疗的POAG患者。通过动态轮廓眼压测量法获得的连续眼压测量值进行快速傅里叶变换信号分析和进一步的统计数据处理。所用统计分析：通过适用于本研究设计的方差分析比较受试对象的眼部和全身特征。P<0.05被认为具有统计学意义。

结果

在两个测试组中，直至第五谐波都能辨别出IOP脉搏波的更高频谱成分。在任何测试的谐波幅度中均未发现统计学上的显著差异。

结论

高眼压症患者和原发性开角型青光眼患者之间IOP脉搏波的频谱成分没有差异，这可能表明病情转变。
