The Australian Reduced Range Extended Spatial Test (ARREST) approach was designed to improve visual field spatial resolution while maintaining a similar test duration to clinically used testing algorithms. ARREST does not completely threshold visual field locations with sensitivity < 17 dB, and uses the presentations saved to test new locations in areas of steep gradient within the visual field. Previous assessments of ARREST's performance have used computer simulation. In this study, we cross-sectionally assessed the performance of ARREST in people with visual field loss.
We tested 23 people with glaucoma (mean age: 71 ± 8 years) with established visual field loss. Three visual field procedures were performed using the Open Perimetry Interface: cZEST and ARREST on the Octopus 900 perimeter (Haag-Streit AG, Switzerland), and a reference standard (best available estimate [BAE]) on the Compass perimeter (CenterVue SpA, Italy). ARREST was compared against the cZEST and the BAE.
On average, ARREST added seven new locations (range = 0-15) to a visual field test. There was no significant difference in the number of stimulus presentations between procedures (mean = 259 ± 25 [ARREST] vs. 261 ± 25 [cZEST], = 0.78). In classifying threshold values < 17 dB, ARREST performed similarly when compared against BAE.
This study provides empirical evidence to support conclusions from previous computer simulations that ARREST can be used to increase spatial sampling in regions of interest without increasing test time.
ARREST is a new approach that augments current visual field testing procedures to provide better spatial description of visual field defects without increasing test duration.
澳大利亚缩小范围扩展空间测试（ARREST）方法旨在提高视野空间分辨率，同时保持与临床使用的测试算法相似的测试时长。ARREST不会对敏感度<17 dB的视野位置进行完全阈值检测，而是使用保存的刺激呈现来测试视野中梯度陡峭区域的新位置。此前对ARREST性能的评估使用的是计算机模拟。在本研究中，我们对有视野缺损的人群进行了ARREST性能的横断面评估。
我们对23名患有青光眼（平均年龄：71±8岁）且已有视野缺损的患者进行了测试。使用开放式视野检测接口进行了三种视野检测程序：在Octopus 900视野计（瑞士Haag-Streit AG公司）上进行cZEST和ARREST检测，以及在Compass视野计（意大利CenterVue SpA公司）上进行参考标准检测（最佳可用估计[BAE]）。将ARREST与cZEST和BAE进行比较。
平均而言，ARREST在一次视野测试中增加了7个新位置（范围为0 - 15个）。各检测程序之间的刺激呈现次数无显著差异（平均值 = 259±25[ARREST] 对比 261±25[cZEST]，P = 0.78）。在对<17 dB的阈值进行分类时，ARREST与BAE相比表现相似。
本研究提供了实证证据，支持先前计算机模拟得出的结论，即ARREST可用于在不增加测试时间的情况下增加感兴趣区域的空间采样。
ARREST是一种新方法，可增强当前的视野测试程序，在不增加测试时长的情况下更好地对视野缺损进行空间描述。
