Diabetic retinopathy (DR) is fundamentally a neurovascular complication initiated and propelled by chronic hyperglycemia. DR represents a significant and escalating public health crisis, inextricably linked to the global diabetes pandemic. Traditional, fragmented healthcare delivery models poorly manage it. In response, integrated care has emerged as a person-centered, holistic framework designed to address these complex, interconnected needs. This narrative review synthesizes the evidence on integrated care for the diabetic patients. It explores the core components and theoretical underpinnings of integrated care, provides a typology of prominent models across primary care, hospital, community, and transitional care settings, and evaluates their evidence-based impact. The analysis covers rising global prevalence of diabetes and its complications creates a problem that standard care methods cannot be met by traditional models of care. Structured, tech-enabled teamwork is the cornerstone of a sustainable, egalitarian, and successful strategy to prevent vision loss from diabetic retinopathy. A comprehensive toolkit for system redesign is provided by the care paradigms examined here, ranging from the proactive coordination of the Patient-Centered Medical Home to the co-located expertise of Integrated Practice Units and the broad reach of teleretinal screening. With the help of data analytics and artificial intelligence, these models will be intelligently integrated to provide more proactive, individualized, and patient-centered care, which will define the future of DR management. The healthcare community may strive to guarantee that no one loses their valuable sight due to a complication that is nearly completely preventable with the correct system in place by adopting this multidisciplinary viewpoint.
