Causes of bilateral low vision (BLLV) and bilateral blindness (BLB) were investigated among 720 outpatients aged > 45 years in Irbid, Jordan, between July 1999 and October 2000. All received full ophthalmic examinations. BLLV was defined as visual acuity < 6/18 but > 3/60 in the better eye; BLB as acuity < 3/60 in the better eye. The leading cause of BLB and BLLV was cataract. Refractive error was the second major cause of BLLV. Other common causes were diabetic retinopathy and glaucoma. Age-related macular degeneration was the single cause of BLB and BLLV for only 1.6% and 2.8% respectively. A population-based survey of BLB and BLLV in the elderly, yearly vision examinations and an ophthalmic education programme are recommended.
1999年7月至2000年10月期间，对约旦伊尔比德720名年龄大于45岁的门诊患者进行了双眼低视力（BLLV）和双眼盲（BLB）病因调查。所有患者均接受了全面的眼科检查。BLLV定义为较好眼视力<6/18但>3/60；BLB定义为较好眼视力<3/60。BLB和BLLV的主要病因是白内障。屈光不正为BLLV的第二大主要病因。其他常见病因是糖尿病视网膜病变和青光眼。年龄相关性黄斑变性分别仅占BLB和BLLV病因的1.6%和2.8%。建议对老年人进行基于人群的BLB和BLLV调查、每年进行视力检查以及开展眼科教育项目。
