The Rising Burden of Diabetes-Related Blindness: A Case for Integration of Primary Eye Care into Primary Health Care in Eswatini

Abstract

There is a rampant increase in diabetes prevalence globally. Sub-Saharan Africa (SSA) is projected to carry the largest burden of diabetes (34.2 million) by 2030. This will inevitably cause a parallel increase in diabetes-associated complications; with the predominant complications being blindness due to diabetic retinopathy and diabetic cataracts. Eye programs in developing countries remain inadequate, existing as stand-alone programs, focused on the provision of acute symptomatic care at secondary and tertiary health levels. Over 60% of people with undiagnosed diabetes report to eye care facilities with already advanced retinopathy. While vision loss due to cataracts is reversible, loss of vision from diabetic retinopathy is irreversible. Developing countries have in the last two decades been significantly impacted by infectious pandemics; with SSA countries committing over 80% of their health budgets towards infectious diseases. Consequently, non-communicable diseases and eye health have been neglected. This paper aimed to highlight the importance of strengthening primary health care services to prevent diabetes-related blindness. In SSA, where economies are strained by infectious disease, the projected rise in diabetes prevalence calls for an urgent need to reorganize health systems to focus on life-long preventative and integrated measures. However, research is critical in determining how best to integrate these without further weakening health systems.
