全国糖尿病防治协作组1994年对全国19省市普查发现,在25～64岁人群中,糖尿病发病率为2.51%,是10年前的3倍左右[1]。糖尿病的高发病率、高增长率使得糖尿病视网膜病变(DR)成为这个年龄段人群致盲的首位原因。所以早期发现、适当治疗、长期随访是减少DR致盲的关键。现将笔者2004 The National Diabetes Control Collaborative Group conducted a survey on 19 provinces and cities nationwide in 1994 and found that among 25-64-year-olds, the incidence of diabetes was 2.51%, about three times that of 10 years ago [1]. The high incidence of diabetes and the high rate of growth make diabetic retinopathy (DR) the leading cause of blindness in this age group. So early detection, proper treatment, long-term follow-up is the key to reduce DR blindness. Now I author
