Twenty-two eyes of 22 patients with initially normaly visual fields developed glaucomatous field defects. In 13 of these, the development of the definitive field defect was preceded by a localized minor disturbance in the area where the defect appeared subsequently. In a control group of 22 ocular hypertensives without field defects, six eyes had localized disturbances similar to those that preceded the field defects in the study group. This type of minor localized disturbance may represent an early glaucomatous visual change detectable before the appearance of definitive scotomas.
22例初始视野正常的患者共22只眼出现了青光眼性视野缺损。其中13只眼在最终视野缺损出现之前，在缺损随后出现的区域有局限性轻度异常。在22例无视野缺损的眼压升高对照组中，6只眼有与研究组视野缺损之前类似的局限性异常。这种类型的轻度局限性异常可能代表在明确的暗点出现之前可检测到的早期青光眼性视觉变化。
