A physiologic fluctuation in threshold levels exists in automated perimetry, which is greater in glaucoma and ocular hypertensive patients than in normal subjects. Fluctuation increases with greater eccentricity from fixation and in areas of reduced retinal sensitivity. Other factors related to automated perimetry testing potentially may influence threshold fluctuation including: a learning effect, reliability, pupil size, age, and the mode of stimulus presentation. Statistical software may aid in analyzing both the single field and the changes between successive fields. However, statistical programs cannot replace physician judgment, and all factors that may influence threshold levels should be considered when interpreting automated visual fields.
自动视野计中存在阈值水平的生理波动，青光眼和高眼压患者的这种波动比正常受试者更大。随着与注视点的偏心度增加以及视网膜敏感度降低的区域，波动会增大。与自动视野计测试相关的其他因素可能会影响阈值波动，包括：学习效应、可靠性、瞳孔大小、年龄以及刺激呈现方式。统计软件可能有助于分析单眼视野以及连续视野之间的变化。然而，统计程序不能取代医生的判断，在解释自动视野检查结果时，应考虑所有可能影响阈值水平的因素。
