Diabetic retinopathy remains a leading cause of preventable blindness, yet uptake of routine eye examinations among people with diabetes continues to lag – particularly in low-resource settings. New data from Northern Uganda provide a timely reminder that, despite clear guidelines, a substantial proportion of patients remain outside the reach of eye care services.
In the cross-sectional study conducted at Gulu Regional Referral Hospital, fewer than half of adults with diabetes (46.8%) reported having undergone an eye examination within the past five years. While this figure is slightly higher than pooled estimates across Africa (~40.9%), it still represents a significant gap in care, especially given recommendations for regular screening to detect diabetic retinopathy at a treatable stage.
The cohort – comprising 419 participants with a median age of 54 years – reflects the typical demographic seen in many diabetic clinics across sub-Saharan Africa: predominantly female, largely affected by type 2 diabetes, and with significant socioeconomic constraints. Notably, more than three-quarters of participants reported low monthly income, and nearly half lived more than 5 km from a health facility, highlighting persistent structural barriers to access.
However, the most striking findings relate not to geography or income, but to knowledge and disease experience. Patients with higher levels of education were significantly more likely to access eye care services, with secondary and tertiary education associated with nearly threefold and twofold increases in uptake, respectively. Similarly, duration of diabetes emerged as a strong predictor: individuals living with the disease for five years or more had markedly higher odds of undergoing eye examinations, likely reflecting increased healthcare contact and the onset of complications.
Perhaps most actionable is the role of patient awareness. Participants who understood that diabetes can affect the eyes were significantly more likely to seek care. Yet, despite 60.6% acknowledging this type of ocular involvement, detailed knowledge of specific complications – such as diabetic retinopathy – still remained limited, suggesting that awareness is often superficial rather than clinically meaningful.
For ophthalmologists, the findings reinforce a familiar but unresolved challenge: access alone is not enough. Even where services exist – often subsidized or free in public systems – utilization depends heavily on health literacy and patient engagement. Cost and lack of awareness were among the most frequently cited reasons for non-attendance, underscoring the interplay between economic and educational barriers.
The clinical implications are clear. Integrating eye care into routine diabetes management – through co-located services, opportunistic screening, or stronger referral pathways – may help to bridge this gap. Equally important is targeted patient education – messaging must go beyond general awareness to emphasize the asymptomatic nature of early diabetic retinopathy and the importance of regular screening.
From a systems perspective, these data also highlight the value of multidisciplinary care models. Collaboration between endocrinologists, primary care providers, and ophthalmologists is essential to ensure that eye health is embedded within broader chronic disease management.
Ultimately, preventing vision loss in diabetes requires more than effective treatments – it demands consistent engagement with patients long before symptoms arise. As this study illustrates, improving utilization may depend less on new technologies and more on addressing the behavioral and educational determinants of care.
