The aim of the study was to establish the correlation between visual filed loss as shown by second-generation Frequency Doubling Technology (Humphrey Matrix) and Standard Automated Perimetry (Humphrey Field Analyser) in patients with glaucoma. Also, compared were the test duration and reliability.
Forty right eyes from glaucoma patients from a private ophthalmology practice were included in this prospective study. All participants had tests within an 8-month period. Pattern deviation plots and mean deviation were compared to establish the correlation between the two perimetry tests. Overall correlation and correlation between hemifields, quadrants and individual test locations were assessed.
Humphrey Field Analyser tests were slightly more reliable (37/40 vs. 34/40 for Matrix)) but overall of longer duration. There was good correlation (0.69) between mean deviations. Superior hemifields and superonasal quadrants had the highest correlation (0.88 [95% CI 0.79, 0.94]). Correlation between individual points was independent of distance from the macula.
Generally, the Matrix and Humphrey Field Analyser perimetry correlate well; however, each machine utilizes a different method of analysing data and thus the direct comparison should be made with caution.
本研究旨在确定青光眼患者中第二代频率加倍技术（Humphrey Matrix）和标准自动视野计（Humphrey视野分析仪）所显示的视野缺损之间的相关性。同时，对测试时间和可靠性进行比较。
本前瞻性研究纳入了一家私立眼科诊所的40例青光眼患者的右眼。所有参与者在8个月内进行了测试。比较模式偏差图和平均偏差，以确定两种视野检查之间的相关性。评估了总体相关性以及半视野、象限和各个测试位置之间的相关性。
Humphrey视野分析仪测试的可靠性略高（Matrix为34/40，视野分析仪为37/40），但总体测试时间更长。平均偏差之间存在良好的相关性（0.69）。上半视野和鼻上象限的相关性最高（0.88[95%CI 0.79，0.94]）。各点之间的相关性与距黄斑的距离无关。
总体而言，Matrix和Humphrey视野分析仪的视野检查相关性良好；然而，每台机器采用不同的数据分析方法，因此直接比较时应谨慎。
