Abstract

Background: Diabetic retinopathy (DR), the primary retinal vascular consequence of diabetes mellitus (DM) among people of working age worldwide, is the primary cause of vision impairment and blindness. Despite increasing understanding of the prevalence of DM as a significant public health concern in China, the world's most populous developing nation, there is much to discover about the epidemiology of DR.

Objective: This work uses a systematic review and meta-analysis to determine the total prevalence of diabetic retinopathy (DR) in China.

Methods: Using common keywords, we looked up published research on the prevalence of DR in diabetic patients using Google Scholar, PubMed, and Scopus from their founding until 2023. Using random effects models, pooled estimates of DR prevalence and the associated 95% confidence intervals (CI) were computed. Fifteen articles covering 4837 patients with different forms of diabetes were analyzed. The Egger tests refuted the publication bias assumption for the prevalence of DR (P = 0.825, P = 0.057, respectively). Significant heterogeneity was seen in the prevalence of DR (P < 0.01, I2 = 92% and τ2 = 0.0082), PDR (P < 0.01, I2 = 97% and τ2 = 0.0072), and NPDR (P < 0.01, I2 = 84% and τ2 = 0.0039), according to the results of I2 and τ2 statistics.

Results: The combined prevalence of PDR was 24% (95% CI: 19-28), NPDR was 31% (95% CI: 27-35), and DR was 55% (95% CI: 63-71).

Conclusions: In summary, DR's prevalence appears slightly higher than that of other studies, with a greater incidence of NPDR. This study emphasises the need for DR screening and treatment in individuals with diabetes.

糖尿病视网膜病变患病率的系统荟萃分析。

背景：糖尿病视网膜病变（DR）是全世界工作年龄人群中糖尿病（DM）的主要视网膜血管后果，是视力损害和失明的主要原因。在中国这个世界上人口最多的发展中国家，人们对糖尿病的患病率作为一个重要的公共卫生问题的认识越来越多，但关于糖尿病的流行病学还有很多需要发现的地方。目的：本研究采用系统回顾和荟萃分析来确定中国糖尿病视网膜病变（DR）的总患病率。方法：使用常用关键词，我们使用谷歌Scholar、PubMed和Scopus从其成立到2023年，查找有关糖尿病患者DR患病率的已发表研究。使用随机效应模型，计算DR患病率的汇总估计和相关的95%置信区间（CI）。我们分析了15篇文章，涵盖了4837名不同形式的糖尿病患者。Egger检验驳斥了DR患病率的发表偏倚假设（P = 0.825, P = 0.057）。DR的患病率存在显著的异质性(P结果：PDR的总患病率为24% (95% CI: 19-28)， NPDR为31% (95% CI: 27-35)， DR为55% （95% CI: 63-71）。结论：总之，DR的患病率似乎略高于其他研究，NPDR的发生率更高。本研究强调了对糖尿病患者进行DR筛查和治疗的必要性。

期刊介绍： Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered: 1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables. 2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words. Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics. 4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors. 5.Letters to the Editors: Discussions or short statements (not indexed).
