Abstract

Purpose

The aim of this study is to explore the prevalence, associated risk factors, and the influence of urbanization on the epidemiology of diabetic retinopathy (DR) and diabetic macular edema (DME).

Methods

This study utilized a cross-sectional design to survey residents aged 50 and older in the Beichen community, Tianjin. Participants underwent thorough examinations, including questionnaire surveys, laboratory blood tests, eye assessments, fundus photography, and optical coherence tomography (OCT) scans. DR was diagnosed using the retinopathy severity scale from fundus photographs based on the Early Treatment Diabetic Retinopathy Study (ETDRS) classification system. DME was identified through medical history records and OCT evaluations. In this study, we analyzed and assessed the prevalence and risk factors associated with DR and DME.

Results

The study included 5,648 participants, and 1,182 of these were diagnosed with diabetes. Among the diabetic individuals, the prevalence of DR was 28.8%. Among the eyes of those diagnosed with DR, 37.12% had mild non-proliferative DR (NPDR), 54.81% had moderate NPDR, 6.35% (33 eyes) showed severe NPDR, and 1.73% had proliferative DR (PDR). The prevalence of DME among diabetic patients was 14.13%. Age was negatively correlated with DR (OR, 0.924), while blood glucose levels (OR, 1.123) and the duration of diabetes (OR, 1.090) were positively correlated. Additionally, blood glucose levels (OR, 1.121) and the duration of diabetes (OR, 1.070) were positively associated with DME.

Conclusion

In this study, the prevalence of DR and DME was high in the Beichen District of Tianjin than in other parts of China. Maintaining effective glycemic control is the most important modifiable factor in reducing the risk of DR and DME progression and minimizing the risk of vision loss.

中国天津郊区人口稠密地区糖尿病视网膜病变的患病率和评估--北辰眼科研究。

目的：本研究旨在探讨糖尿病视网膜病变（DR）和糖尿病黄斑水肿（DME）的患病率、相关危险因素以及城市化对其流行病学的影响：本研究采用横断面设计，对天津市北辰社区 50 岁及以上的居民进行了调查。参与者接受了全面的检查，包括问卷调查、实验室验血、眼部评估、眼底照相和光学相干断层扫描（OCT）。根据早期治疗糖尿病视网膜病变研究（ETDRS）的分类系统，通过眼底照片的视网膜病变严重程度量表诊断出糖尿病视网膜病变。通过病史记录和 OCT 评估确定了 DME。在这项研究中，我们分析并评估了与 DR 和 DME 相关的患病率和风险因素：研究共纳入了 5648 名参与者，其中 1182 人被确诊为糖尿病。在糖尿病患者中，DR 的患病率为 28.8%。在确诊为 DR 的患者中，37.12% 患有轻度非增殖性 DR（NPDR），54.81% 患有中度非增殖性 DR，6.35%（33 眼）患有重度非增殖性 DR，1.73% 患有增殖性 DR（PDR）。糖尿病患者中 DME 的发病率为 14.13%。年龄与 DR 呈负相关（OR，0.924），而血糖水平（OR，1.123）和糖尿病病程（OR，1.090）呈正相关。此外，血糖水平（OR，1.121）和糖尿病病程（OR，1.070）与 DME 呈正相关：结论：与中国其他地区相比，天津市北辰区的 DR 和 DME 患病率较高。保持有效的血糖控制是降低DR和DME进展风险、减少视力丧失风险的最重要的可改变因素。
