Perimetry is essential for identifying visual field defects due to disorders of the eye and brain. However, young children are often unable to reliably perform the preferred method of visual field assessment known as automated static perimetry (ASP). This paper introduces a novel method of ASP specifically developed for children called Saccadic Vector Optokinetic Perimetry (SVOP). SVOP uses eye tracking to detect the natural saccadic eye response of gaze orientation towards visual field stimuli if they are seen. In this paper, the direction and magnitude of a sample of subject gaze responses to visual field stimuli is used to construct a software decision algorithm for use in SVOP. SVOP was clinically evaluated in a group of 24 subjects, comprising children and adults, with and without visual field defects, by comparison with an equivalent test on the Humphrey Field Analyser (HFA). SVOP provides promising visual field test results when compared with the reference HFA test, and has proven extremely useful in detecting visual field defects in children unable to perform traditional ASP.
视野检查对于识别因眼睛和脑部疾病导致的视野缺损至关重要。然而，幼儿往往无法可靠地采用被称为自动静态视野检查（ASP）的首选视野评估方法。本文介绍了一种专门为儿童开发的新型ASP方法，称为扫视向量视动视野检查（SVOP）。SVOP利用眼动追踪来检测如果看到视野刺激时，眼睛自然的扫视反应中注视方向的变化。在本文中，受试者对视野刺激的注视反应样本的方向和大小被用于构建一个用于SVOP的软件决策算法。通过与汉弗莱视野分析仪（HFA）上的等效测试进行比较，对一组24名受试者（包括有和没有视野缺损的儿童和成人）进行了SVOP的临床评估。与参考HFA测试相比，SVOP提供了有前景的视野测试结果，并且已证明在检测无法进行传统ASP的儿童的视野缺损方面极其有用。
