The problem of glaucoma as a cause of blindness is discussed. WHO has proposed five classes of sightlessness on the sole basis of visual acuity without taking into account sense of luminosity, peripheral vision, color vision. In addition, different nations have different tables for evaluating the severity of the handicap so that data on this subject cannot be compared. This is why the problem of blindness due to glaucoma is very complicated and the concept of blindness has to be standardized as well as the method of epidemiologic research. The investigation starts from a list of the most reliable sources: records of associations of sightless subjects, lists of sightless persons receiving an invalidity pension, filed research, records of support activities and transversal population studies. This is followed by a general review of causes of blindness worldwide, their prevalence according to age and sex, and especially the causes of blindness in various nations and in different regions of Italy. Last, the percentage of loss of eye-sight due to glaucoma is examined.
本文讨论了青光眼作为致盲原因的问题。世界卫生组织仅根据视力提出了五类失明情况，而未考虑光感、周边视力和色觉。此外，不同国家有不同的评估残疾严重程度的表格，因此关于这一主题的数据无法进行比较。这就是为什么青光眼致盲问题非常复杂，失明的概念以及流行病学研究方法都必须标准化。调查从一系列最可靠的来源开始：失明者协会的记录、领取残疾抚恤金的失明人员名单、存档研究、支持活动记录和横向人群研究。接下来是对全球失明原因、按年龄和性别划分的患病率，特别是意大利不同国家和不同地区的失明原因进行总体回顾。最后，研究了因青光眼导致的视力丧失百分比。
