目的确定苏格兰西部可登记盲和视力障碍的总体报告发病率和原因，以及自同一地区数据发表以来的16年中发生的任何趋势。方法分析数据来自1996年4月1日至1999年12月30日期间返回苏格兰西部斯特拉斯克莱德地区盲人资源中心的BP 1登记表。结果本研究年共登记视障者1595人。其中，99份表格（6.2%）因信息不足而被排除在进一步分析之外。其余1 496份已填写的BP1表格涉及530名男性和966名女性。其中，253名男性和450名女性为法定失明（共703人或47.0%），277名男性和516名女性为部分失明（共793人或53.0%）。五大致盲原因依次为年龄相关性黄斑变性、青光眼、糖尿病视网膜病变、近视变性和视神经萎缩。ARMD和糖尿病视网膜病变是最常见的致盲原因，在那些超过65岁和工作年龄的人，分别。结论在成年人中，白内障不再是一个显着的原因登记视力损害。自1983年以来，青光眼、糖尿病视网膜病变和近视的登记比例没有明显变化，黄斑变性的比例有所增加。在儿童中，先天性青光眼、白内障和角膜感染不再是登记的原因，但脑损伤引起的视力损害现在是一个重要的原因。
Aims To determine the overall reported incidence and causes of registrable blindness and visual impairment in the West of Scotland and any trends that have occurred in the previous 16 years since data from the same area were published.Methods Data for analysis were obtained from BP1 registration forms returned to the Resource Centre for the Blind serving the Strathclyde region in the West of Scotland between 1 April 1996 and 31 March 1997.Results A total of 1595 visually handicapped people were registered during the study year. Of these, 99 forms ( 6.2%) were excluded from further analysis because of insufficient information. The remaining 1496 completed BP1 Forms were in respect of 530 males and 966 females. Of these, 253 males and 450 females were legally blind ( total 703 or 47.0%) and 277 males and 516 females were partially sighted ( total 793 or 53.0%). The five leading causes of blindness, in decreasing frequency, were age-related macular degeneration (ARMD), glaucoma, diabetic retinopathy, myopic degeneration, and optic atrophy. ARMD and diabetic retinopathy were the most common causes of blindness in those over 65 years and persons of working age, respectively.Conclusions In adults, cataract is no longer a significant cause of registrable visual impairment. The proportions of registrations owing to glaucoma, diabetic retinopathy, and myopia have not significantly changed since 1983 and the proportion owing to macular degeneration has increased. In children, congenital glaucoma, cataract, and corneal infection were no longer causes of registration, but impairment of vision caused by brain damage is now a significant contributor.
