The optimization of visual field screening programs for glaucoma requires precise knowledge of where glaucoma defects occur and whether any relation exists between the size of defects and the associated retinal disease. The visual field results from 109 eyes of patients with early glaucomatous damage were investigated with a Friedmann Mark II Visual Field Analyser. The frequency distribution of scotomas as a function of location demonstrated that the tested field could be divided into four zones, one where scotomas occur frequently, one where scotomas occur a reasonable number of times, one where scotomas occur rarely, and one which corresponds to the blind spot (BS) region. The distribution of scotoma size in the first three zones was found to be about the same. Differences among the distributions of defects measured in this study and those of previous studies are attributed to different examination techniques.
青光眼视野筛查项目的优化需要精确了解青光眼缺损出现的位置，以及缺损大小与相关视网膜疾病之间是否存在任何关联。使用弗里德曼Mark II视野分析仪对109例早期青光眼性损害患者的视野结果进行了研究。暗点频率分布作为位置的函数表明，测试视野可分为四个区域，一个是暗点频繁出现的区域，一个是暗点出现次数合理的区域，一个是暗点很少出现的区域，还有一个对应于盲点（BS）区域。发现前三个区域的暗点大小分布大致相同。本研究中测量的缺损分布与先前研究的分布差异归因于不同的检查技术。
