Prevalence of diabetic retinopathy in Brazil: a systematic review with meta-analysis

Abstract

Aims To evaluate the prevalence of diabetic retinopathy (DR) in Brazilian adults with diabetes mellitus via a systematic review with meta-analysis. Methods A systematic review using PubMed, EMBASE, and Lilacs was conducted, searching for studies published up to February 2022. Random effect meta-analysis was performed to estimate the DR prevalence. Results We included 72 studies (n = 29,527 individuals). Among individuals with diabetes in Brazil, DR prevalence was 36.28% (95% CI 32.66–39.97, I2 98%). Diabetic retinopathy prevalence was highest in patients with longer duration of diabetes and in patients from Southern Brazil. Conclusion This review shows a similar prevalence of DR as compared to other low- and middle-income countries. However, the high heterogeneity observed—expected in systematic reviews of prevalence—raises concerns about the interpretation of these results, suggesting the need for multicenter studies with representative samples and standardized methodology.

“…The prevalence of DR in Pakistan was reported to be 28%, with 9% of patients having eye disease severe enough to threaten their sight. The prevalence of DR in Pakistan was reported to be 28%, with 9% of patients having eye disease severe enough to threaten their sight [ 21 , 38 ]. The same study also reported that the prevalence of DR ranges from 10.6% to 91.34% [ 38 ], and that sight-threatening diseases very between 4% and 46% [ 20 , 23 ].…”

“…Al igual que diferentes complicaciones, entre ellas la retinopatía diabética, que es la más común de las complicaciones en pacientes con DM. Con tasas notoriamente altas, como en el caso de Brasil por ejemplo, en dónde se estima entre el 7 al 44% de todos los pacientes con DM (Chagas et al, 2023).…”
