AIMS/BACKGROUND: Automated perimetry is both one of the most important diagnostic procedures in ophthalmology and the most difficult for the patient who is required to comply with strict and tiring conditions. This paper examines the use of a moving fixation target and a strategy for full threshold determination only in those data points found to be abnormal.
142 eyes in 71 patients were subjected to two types of visual field tests: the Dicon TKS 4000 Autoperimeter program 5 and the Humphrey field analyser program 30/2. The first procedure was compared with a commonly used instrument and strategy that is usually employed for the management of glaucoma patients.
Such a strategy was used in patients presenting with neuro-ophthalmic problems taking an average testing time of 14.9 minutes. The alternative test described here took an average of 3.9 minutes, without loss of diagnostic value.
The shorter testing time results in greater patient acceptance, fewer fatigue induced artefacts, and the possibility of completing a perimetry test with patients whose ability might seriously be challenged by a longer test. The reduced time required and the more natural condition of not having to fixate on an unmoving position were found not to reduce the diagnostic value of the data produced in patients presenting for various reasons at a neuro-ophthalmology clinic.
目的/背景：自动视野计检查既是眼科最重要的诊断程序之一，也是对患者而言最困难的程序，因为患者需要遵守严格且累人的条件。本文研究了移动注视目标的使用以及仅在发现异常的数据点进行全阈值测定的策略。
对71例患者的142只眼睛进行了两种视野测试：Dicon TKS 4000自动视野计程序5和Humphrey视野分析仪程序30/2。将第一种程序与通常用于青光眼患者管理的常用仪器和策略进行了比较。
在患有神经眼科问题的患者中使用了这种策略，平均测试时间为14.9分钟。这里描述的替代测试平均需要3.9分钟，且不损失诊断价值。
较短的测试时间会使患者接受度更高，疲劳引起的伪像更少，并且对于那些可能因较长测试而严重影响其能力的患者来说，有可能完成视野计检查。研究发现，所需时间的减少以及无需注视在固定位置的更自然条件，并不会降低因各种原因到神经眼科诊所就诊患者所产生数据的诊断价值。
