据报道，根据加拿大国家盲人研究所 (C.N.I.B.) 的登记，对加拿大盲人进行了一项调查。这是同类研究中第一项具有全国范围且基于中央档案中登记的数据的研究。它覆盖了从早产儿到高龄老人的 24,605 名在世登记盲人。失明原因根据地形（病变部位和类型）和病因进行分类。从发生频率来看，主要原因是影响眼球的病变（例如青光眼、近视），36%；视网膜，23%；镜头，16%；和视神经，11%。在这项研究中，32% 的失明是由于产前原因造成的。根据 C.N.I.B.，加拿大每 10 万人的失明率数据显示，该数字为 131，各省份从 108 到 376 不等。严重眼部疾病的患病率是失明的四倍； C.N.I.B. 列出了 101,436 例此类病例（预防组）。
A survey of blind persons in Canada, based on registrations with The Canadian National Institute for the Blind (C.N.I.B.), is reported. This is the first study of its type having national scope and based on data registered in a central file. It covered 24,605 living registered blind persons ranging from premature infants to very elderly persons. Causes of blindness are broken down with respect to topography (site and type of lesion) and etiology. In terms of frequency, the principal causes were lesions affecting the globe (e.g. glaucoma, myopia), 36%; the retina, 23%; the lens, 16%; and the optic nerve, 11%. In this study, 32% of the blindness was due to prenatal causes. The prevalence of blindness per 100,000 persons in Canada, based on C.N.I.B. data, was 131, varying among the provinces from 108 to 376. Serious ocular disease was four times more prevalent than blindness; 101,436 such cases (the prevention group) were listed by the C.N.I.B.
