A total of 75 eyes in 75 patients with different types of glaucoma (21 eyes with low-tension glaucoma, 49 with primary open-angle glaucoma and 5 with pigmentary glaucoma) were examined by automated light-sense, flicker and resolution perimetry. All fields were classified in a masked fashion as being "normal" (N) or as having "diffuse loss" (D), "localized loss" (L) or "diffuse plus localized loss" (DL). The frequency distributions for the various field loss categories were plotted against the highest intraocular pressure ever reported in the patients' records. The frequency distribution for the purely localized defects showed a peak at 20 mmHg and were markedly skewed to low pressure values, whereas those for both diffuse plus localized damage and purely diffuse loss peaked at about 30 mmHg. The data suggest that diffuse field loss may be an indicator of pressure-induced damage.
对75例不同类型青光眼患者（21例低眼压性青光眼、49例原发性开角型青光眼和5例色素性青光眼）的75只眼睛进行了自动光感、闪烁和分辨率视野检查。所有视野均以盲法分类为“正常”（N）或有“弥漫性缺损”（D）、“局限性缺损”（L）或“弥漫性加局限性缺损”（DL）。将各种视野缺损类别的频率分布与患者记录中报告的最高眼压进行对比绘制。单纯局限性缺损的频率分布在20 mmHg处出现峰值，且明显偏向于低压值，而弥漫性加局限性损害和单纯弥漫性缺损的频率分布在约30 mmHg处出现峰值。数据表明，弥漫性视野缺损可能是压力性损伤的一个指标。
