BACKGROUND
Rarebit perimetry (RBP), a technique developed for the detection of early damage to the afferent visual system, has not been extensively tested at the bedside. This study was designed to test the feasibility of bedside testing with RBP in comparison with standard automated perimetry (SAP) performed in the clinic.
METHODS
We tested 29 eyes of 15 subjects admitted with neurologic or neurosurgical diseases affecting the afferent visual system. RBP was performed on a laptop computer at the bedside. SAP (Humphrey field analyzer) testing was performed later in the clinic. Results were evaluated by a masked neuro-ophthalmologist.
RESULTS
Visual fields corresponded between RBP and SAP in 21(72%) of the 29 tested eyes. RBP detected defects in 5 subjects who had normal visual field results on SAP. All subjects preferred RBP for convenience.
CONCLUSION
RBP is a convenient method of bedside visual field testing and is no less sensitive to visual field defects in this role than SAP.
背景
罕见的视野计（RBP），一种用于检测传入视觉系统早期损伤的技术，尚未在床边进行广泛测试。本研究旨在测试床边使用 RBP 进行测试的可行性，并与在诊所进行的标准自动视野计（SAP）进行比较。
方法
我们测试了 15 名患有影响传入视觉系统的神经或神经外科疾病的受试者的 29 只眼睛。RBP 在床边的笔记本电脑上进行。稍后在诊所进行 SAP（Humphrey 视野分析仪）测试。结果由一位盲法神经眼科医生进行评估。
结果
在测试的 29 只眼中，21 只（72%）的视野与 RBP 和 SAP 相符。RBP 在 5 名 SAP 视野正常的受试者中检测到了缺陷。所有受试者都更喜欢 RBP 的便利性。
结论
RBP 是一种方便的床边视野测试方法，在该作用下，其对视野缺陷的敏感性不亚于 SAP。
