FDT视野计是一种紧凑且相对便宜的视野计，其可运输性、对屈光不正的耐受性和快速测试时间（每只眼睛不到1分钟）使其成为视野筛查的合适候选者。一致的发现是，FDT视野计的C-20-1筛选方案为检测青光眼中的中度和重度损失提供了良好的灵敏度和特异性。通过使用C-20-5筛选方案可以提高灵敏度。此外，FDT视野计对于检测神经眼科疾病的存在表现出良好的灵敏度和特异性，尽管其确定视野缺损是否为偏盲的能力有限。只有有限的证据表明FDT可以适当地检测视网膜疾病。尽管有一些证据表明，目前的FDT视野计可能适用于分期和监测视野损伤的进展，但测试中使用的大目标使其实用性有限。倍频测试的发展与较小的目标间隔在较窄的间隔将提高FDT视野检查的能力，以确定视野缺损的空间范围。
The FDT perimeter is a compact and relatively inexpensive perimeter whose transportability, tolerance to refractive errors, and rapid test times (less than 1 minute per eye) make it a suitable candidate for visual field screening. It is a uniform finding that the C-20-1 screening protocol of the FDT perimeter provides good sensitivity and specificity for the detection of moderate and severe losses in glaucoma. Sensitivity can be increased by use of the C-20-5 screening protocol. In addition, the FDT perimeter demonstrates good sensitivity and specificity for detecting the presence of neuro-ophthalmic disorders, though it may have a limited ability to determine whether a field defect is hemianopic. There is only limited evidence that the FDT can appropriately detect retinal disease. Despite some evidence that the current FDT perimeter may be suitable for staging and monitoring the progression of visual field damage, the large targets used in the test make this of limited practicability. The development of a frequency-doubling test with smaller targets spaced over narrower intervals would improve the ability of FDT perimetry to determine the spatial extent of visual field defects.
