正常视野的形状和高度随着年龄的增长而变化。个体间、测试内和测试间的变异在整个视野中并不是恒定的，而是取决于偏心度。测量的阈值与年龄校正的正常阈值的偏差是非高斯的，显示出显着的偏心率相关的负偏度和正峰度。当对视野测试的结果进行统计分析时，必须考虑这些观察结果，否则可能会得到误导性的结果。受测患者的视野体验程度以及可靠性测试的结果是视野（统计）评估中值得考虑的其他重要因素。正常人群中现场缺陷的发生率可能比以前认识的要高得多。青光眼嫌疑人的所有视野损失不应自动归因于青光眼。
The normal visual field changes both shape and height with age. Inter-individual, intratest and inter-test variation are not constant across the visual field but depend on eccentricity. Deviations of measured thresholds from the age-corrected normal threshold are non-Gaussian showing significant eccentricity-dependent negative skewness and positive kurtosis. These observations must be taken into account when results of visual field testing are subjected to statistical analysis, or misleading results may be obtained. The degree of perimetric experience of the tested patient as well as the results of reliability tests are other important factors worth considering in the (statistical) evaluation of visual fields. The prevalence of field defects in the normal population might be considerably higher than previously recognized. All field loss in glaucoma suspects should not automatically be attributed to glaucoma.
