Diabetic retinopathy screening model in low and middle-income countries: a scoping review.

ABSTRACT:

Background

Diabetic retinopathy (DR), a leading cause of blindness in working-age adults, disproportionately affects low- and middle-income countries (LMICs). While preventable through early intervention, DR screening programs are often lacking in these resource-constrained settings.

Objective

This scoping review examines DR screening models implemented in LMICs, identifying evidence, research gaps, and potential improvement strategies.

Methods

A literature search across multiple databases identified studies on DR screening in LMICs, limited to peer-reviewed articles from the past 20 years focusing on DR screening model effectiveness or implementation. Key data (study design, screening techniques, outcomes) were extracted and synthesized narratively.
