Global, Regional, and National Burden of Blindness due to Diabetic Retinopathy, 1990-2021.

ABSTRACT:

Introduction

This study aimed to analyze the patterns and trends in the burden of blindness due to diabetic retinopathy (DR) from 1990 to 2021 at the global, regional, and national levels.

Methods

We conducted a population-based analysis using the latest data from the Global Burden of Disease Study 2021. We examined the prevalence and number of cases of DR-related blindness stratified by type of diabetes, sex, age, and sociodemographic index (SDI) level. The trends in the blindness burden were quantified via the average annual percentage changes. A decomposition analysis was performed to identify key drivers of the changing burden. A Bayesian age‒period‒cohort model was used to predict the future burden of DR-related blindness from 2022 to 2035.
