除了对不同视野指数的计算进行数学描述之外，还给出了用于评估定量视野的统计方法。“平均缺陷”对于弥漫性损伤以及晚期的随访都很重要。“短期波动”提供了有关结果的可靠性以及可能的早期损害的信息。“修正损失方差”在早期阶段量化局部缺陷；它也将真实的局部缺陷从增加的散布中分离出来。“偏斜度”是对非常早期的局部缺陷的测试，而“空间相关性”提供了对可能存在的任何局部缺陷的聚集性的测量。
Statistical methods for the evaluation of quantitative visual fields are presented in addition to a mathematical description of the calculation of different visual field indices. The "mean defect" is important for diffuse damage as well as for follow-up in advanced stages. "Short-term fluctuation" provides information about the reliability of the results as well as about possible early damage. "Corrected loss variance" quantifies local defects in an early stage; it also separates real local defects from increased scatter. "Skewness" is a test for very early local defects, and "spatial correlation" provides a measurement of the clustering of any local defects that may be present.
