The Conformity Analysis is a new procedure for objective recognition of specific defect patterns in automated perimetry. The "Conformity Index," the measure of conformity between the distribution of defect values and several standard defect patterns, is calculated from the ratio of global variance and mean variance in particular regions. Using 68 visual fields from 68 normal persons, we determined normal values and limits of the Conformity Index for seven standard defect patterns: hemifields right-left, hemifields upper-lower, quadrants, sectors, rings with 5 degrees and 10 degrees radius interval and the perimetric nerve fiber bundles of Weber and Ulrich. The evaluation of 148 visual fields (68 normal eyes, 80 eyes with chronic glaucoma and all stages of damage) by both the Conformity Index and two experienced clinicians revealed an identical result in 89%. Using the Conformity Analysis in 37 cases of pituitary adenoma, we could objectively identify quadrants, sectors and hemifields right-left to be the most common defect patterns in this disease. In glaucoma fields with marked damage (n = 46), the most frequent pathological Conformity Index was the index for perimetric nerve fiber bundles.
一致性分析是一种用于在自动视野检查中客观识别特定缺陷模式的新方法。“一致性指数”是缺陷值分布与几种标准缺陷模式之间一致性的度量，它是根据特定区域的总体方差与平均方差之比计算得出的。我们使用68名正常人的68个视野，确定了七种标准缺陷模式的一致性指数的正常值和界限：左右半视野、上下半视野、象限、扇形、半径间隔为5度和10度的环以及Weber和Ulrich的视野神经纤维束。通过一致性指数和两位经验丰富的临床医生对148个视野（68只正常眼、80只患有慢性青光眼及所有损伤阶段的眼睛）进行评估，结果显示89%的结果相同。在37例垂体腺瘤病例中使用一致性分析，我们能够客观地确定象限、扇形和左右半视野是该疾病中最常见的缺陷模式。在损伤明显的青光眼视野（n = 46）中，最常见的病理性一致性指数是视野神经纤维束的指数。
