To investigate the causes of visual impairment in Japan.
The documents of 4,852 individuals with authorization of visual impairment registered between April 2007 and March 2010 in 7 randomly selected regions were reviewed.
The major causes of visual impairment were glaucoma (21.0%), diabetic retinopathy (15.6%), retinitis pigmentosa (12.0%), macular degeneration (9.5%) and chorioretinal atrophy (8.4%). Individuals over 70 years of age were predominant for glaucoma, those aged 50-69 years for diabetic retinopathy and those under 40 years of age for retinitis pigmentosa. Sixty-one percent of persons affected by glaucoma were severely handicapped. Macular degeneration increased with age especially in individuals over 80 years of age.
There was no difference in the order of major causes as compared with a previous report in 2001-2004. It is important to establish a central database system so that the data can be surveyed to provide more relevant information to understand current issues for handicapped persons and develop new prophylactic and therapeutic modalities.
调查日本视力损害的原因。
回顾了2007年4月至2010年3月期间在7个随机选择地区登记的4852名获得视力损害授权者的文件。
视力损害的主要原因是青光眼（21.0%）、糖尿病视网膜病变（15.6%）、视网膜色素变性（12.0%）、黄斑变性（9.5%）和脉络膜视网膜萎缩（8.4%）。70岁以上人群以青光眼为主，50 - 69岁人群以糖尿病视网膜病变为主，40岁以下人群以视网膜色素变性为主。61%的青光眼患者有严重残疾。黄斑变性随年龄增长而增加，尤其是80岁以上的个体。
与2001 - 2004年的先前报告相比，主要原因的顺序没有差异。建立一个中央数据库系统很重要，以便对数据进行调查，为了解残疾人的当前问题并开发新的预防和治疗方法提供更多相关信息。
