摘要
糖尿病视网膜病变在1型糖尿病中更常见（1型糖尿病患者有40％存在糖尿病视网膜病变，2型糖尿病患者有20％）。在英国，糖尿病视网膜病变是上班族失明的主要病因，给公共医疗卫生服务带来很大的负担。目前，大约2％的英国人有糖尿病，其中，有10％～13％存在着威胁视力的糖尿病视网膜病变。增殖期糖尿病视网膜病变的患者发生心脏病发作、卒中、糖尿病性肾病、截肢以及死亡的危险性增高。
Diabetic retinopathy is more common in type 1 diabetes （40% of patients） than in type 2 （20%）. In the UK, it is the principal cause of blindness in individuals of working age and places a significant burden on health services. At least 2% of the UK population are currently known to have diabetes, and 10-13% of these have sight-threatening retinopathy. Patients with proliferative diabetic retinopathy are at increased risk of heart attack, stroke, diabetic nephropathy, amputation and death.
