Abstract

Purpose: Although the rate of diabetic retinopathy (DR)-related blindness has decreased in developed countries in recent years, the reasons for this decrease have remained unclear. The prevalence/severity trends of DR at the first visit in patients with untreated type 2 diabetes mellitus (T2DM) patients seen between the1986s and 2018s were assessed.

Methods: A total of 1979 Japanese T2DM patients diagnosed between 1986 and 2018 were divided into four groups by the decade of their first visit: the 1986 years (1986-1987), the 1996 years (1996-1997), the 2006 years (2006-2008), the 2016 years (2016-2018). The DR prevalence/severity trends were assessed.

Results: A significant decrease in the rate of prevalence of DR from the 1986s to 2016s was observed among previously untreated T2DM patients visiting our hospital for the first time (1986s: 25.5%; 1996s: 26.2%; 2006s: 22.2%; and 2016s: 15.6%). The prevalence was significantly higher in females (30.2%) than in males (21.3%). Although the severity trend of DR did not differ significantly among the four measurement years, the rate of simple DR was the highest in the 2016s.

Conclusion: We found, for the first time, a significant decrease in the rate of prevalence of DR from the 1986s to 2016s in patients with untreated T2DM visiting our hospital for the first time. A decrease in the rate of DR prevalence could explain, at least in part, the observed reduction in the rate of blindness in patients with T2DM.

未经治疗的 2 型糖尿病患者首次就诊时糖尿病视网膜病变患病率和严重程度的三十年趋势。

目的：虽然近年来发达国家与糖尿病视网膜病变（DR）相关的失明率有所下降，但下降的原因仍不清楚。研究评估了1986-2018年间未接受治疗的2型糖尿病（T2DM）患者首次就诊时DR的患病率/严重程度趋势：将1986年至2018年间确诊的1979名日本T2DM患者按初诊年代分为四组：1986年（1986-1987年）、1996年（1996-1997年）、2006年（2006-2008年）、2016年（2016-2018年）。对 DR 发病率/严重程度趋势进行了评估：从 1986 年代到 2016 年代，首次到本医院就诊的既往未经治疗的 T2DM 患者的 DR 患病率明显下降（1986 年代：25.5%；1996 年代：26.2%；2006 年代：22.2%；2016 年代：15.6%）。女性发病率（30.2%）明显高于男性（21.3%）。虽然 DR 的严重程度趋势在四个测量年份之间没有显著差异，但 2016 年代的单纯 DR 患病率最高：我们首次发现，从 1986 年代到 2016 年代，首次到我院就诊的未经治疗的 T2DM 患者的 DR 患病率显著下降。DR 患病率的下降至少可以部分解释所观察到的 T2DM 患者失明率的下降。

期刊介绍： Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
