我们评估了正常受试者中央30度视野的计算机化静态阈值视野检查结果的变异性。测量阈值的可变性高度依赖于偏心率。这包括个体之间的变异性，个体内的测试对测试变异性，以及最内部的变异性。所有的值在中周部明显大于中央部。我们发现，平均敏感度随年龄的降低是偏心依赖的，因此，经年龄校正的正常视野不仅随着年龄的增长而变得黯淡，而且还变得更加陡峭。个体与年龄校正的正常平均阈值的点状偏差的分布明显不符合高斯分布。在对计算机化视野的解释中，尤其是在设计用于视野分析的统计程序时，应考虑变异性对测试点位置的依赖性、偏离年龄校正均值的非高斯分布以及年龄引起的敏感度降低的变异性。没有考虑这些因素的程序可能会导致误导性的分析。
We assessed the variability of results in normal subjects of computerized static threshold perimetry of the central 30 degrees field. Variability of measured threshold values was highly dependent on eccentricity. This included variability among individuals, test-to-test variability within individuals, and intratest variability. All values were significantly larger in the midperiphery than centrally. We found that the mean sensitivity decrement with age was eccentricity dependent, so that the age-corrected normal visual field became not only depressed but also steeper with age. Distributions of individual pointwise deviations from the age-corrected normal mean thresholds were significantly nongaussian. The dependency of variability on test point location, the nongaussian distributions of deviations from age-corrected means, and the variability of age-induced sensitivity reduction should all be considered in the interpretation of computerized visual fields, and particularly in the design of statistical programs for field analysis. Programs not considering these factors are likely to result in misleading analyses.
