Abstract

Aims: This study aimed to report the global prevalence of diabetic retinopathy (DR) based on retinal imaging, using English-language articles published from 2017 to June 2024. Methods: Three databases—Cochrane Library, Embase via OVID, and Medline via OVID—were searched using subject headings and ke...

An independent librarian conducted the initial search and developed the strategy. A total of 569 publications were uploaded to Rayyan for blinded screening, yielding 42 studies. Meta-analysis was performed to determine prevalence rates for any DR, proliferative DR (PDR), diabetic macular oedema (DMO), and sight-threatening DR (STDR). Results: Global prevalence rates across the 7 IDF regions were: any DR 23&#x202F;% (95&#x202F;% CI: 20&#x2013;26), PDR 6&#x202F;% (95&#x202F;% CI: 3&#x2013;9), DMO 5&#x202F;% (95&#x202F;% CI: 4&#x2013;6), and STDR 11&#x202F;% (95&#x202F;% CI: 9&#x2013;14). Compared to 2015&#x2013;2019 data, the rate of any DR decreased from 27&#x202F;% to 23&#x202F;%, while PDR increased from 1.4&#x202F;% to 6&#x202F;%. DMO rates remained stable (&#x223C;5%). Conclusion: Global DR prevalence remains between 20 and 30%. However, variations in study design and regional practices limit trend interpretation.
