Perimetry is the standard examination in glaucoma, whereas contrast sensitivity is often proposed as a complementary test. This study investigates the extent to which the outcomes of the two tests correlate. One eye each of 44 glaucoma patients and 16 glaucoma suspects was tested with the Haag-Streit Visometer and the Octopus 201 perimeter (program G1). Contrast sensitivities correlated highest with the center of the visual field (Spearman's rho = 0.76; P < 0.001) and slightly less with the mean sensitivity of the entire visual field (rho = 0.63; P < 0.001). Mean contrast sensitivity correlated weakly with the square root of corrected loss variance (rho = -0.45; P < 0.001) and short-term fluctuation (rho = -0.34; P < 0.007). The two tests differed considerably only in very few patients. We recommend careful evaluation of the central area of glaucomatous visual fields whenever contrast sensitivity testing is not available.
视野检查是青光眼的标准检查方法，而对比敏感度常被提议作为一种补充检查。本研究调查了这两种检查结果的相关程度。对44例青光眼患者和16例青光眼疑似患者的单眼进行了Haag-Streit视力计和Octopus 201视野计（程序G1）检查。对比敏感度与视野中心的相关性最高（斯皮尔曼等级相关系数ρ = 0.76；P < 0.001），与整个视野的平均敏感度的相关性稍低（ρ = 0.63；P < 0.001）。平均对比敏感度与校正损失方差的平方根（ρ = -0.45；P < 0.001）和短期波动（ρ = -0.34；P < 0.007）的相关性较弱。这两种检查仅在极少数患者中有显著差异。我们建议，在无法进行对比敏感度检测时，应仔细评估青光眼视野的中心区域。
