Rarebit vision tests probe for gaps in the neuro-retinal receptive field matrix, using bright micro dots on a dark background. Previous reports have found central-vision rarebit tests useful for macular lesions. Their performance with lesions of the anterior visual pathways has not been explored.
Twenty-two subjects with optic nerve lesions of light to moderate severities were examined with a novel, self-contained rarebit test. Outcomes were contrasted with results of high-pass resolution perimetry and a threshold letter acuity test.
The results of the three tests differed significantly from those of normal control subjects. There were no meaningful inter-test correlations. Analysis of receiver-operating characteristic curves revealed closely similar powers of discrimination. Mean test time for the rarebit test was 1:42 min, and for the other tests, it was approximately 5 min each.
The rarebit test appeared highly capable of detecting optic neuropathies and chiasmal lesions. Its simplicity and short test duration indicate a useful role in screening settings.
稀干酪视野测试利用暗背景上的明亮微点来探测神经视网膜感受野矩阵中的间隙。先前的报告发现中央视野稀干酪测试对黄斑病变有用。其在前视觉通路病变中的表现尚未得到研究。
对22名轻度至中度视神经病变患者进行了一项新型的、独立的稀干酪测试。将结果与高通分辨率视野检查和阈值视力字母测试的结果进行对比。
这三项测试的结果与正常对照受试者的结果有显著差异。测试之间没有有意义的相关性。对受试者工作特征曲线的分析显示，辨别能力非常相似。稀干酪测试的平均测试时间为1分42秒，其他测试每项约为5分钟。
稀干酪测试似乎非常能够检测视神经病变和视交叉病变。其简单性和较短的测试时间表明在筛查环境中具有有用的作用。
