As World Retina Week highlights the importance of early diagnosis, Africa faces a mounting challenge with diabetic eye disease and retinal conditions that threaten sight, emphasising the need for regular screening and prompt treatment.
World Retina Week, observed from September 23 to 29, is drawing attention to a part of the eye that is easy to overlook but vital to sight: the retina. This light-sensitive tissue at the back of the eye converts incoming light into the images the brain understands, and once it is damaged, it cannot regenerate. That makes early diagnosis particularly important, because many retinal conditions progress quietly long before a person notices a problem.
Across sub-Saharan Africa, retinal disease is already a significant cause of specialist eye-care visits. Information cited in the source material says diabetic eye disease, retinal detachment and age-related macular degeneration together account for more than 60% of retinal diagnoses in clinics in the region. The wider message from retina specialists is consistent: retinal tears and detachments can lead to lasting vision loss if they are not found and treated quickly, but prompt intervention can often stop a tear from becoming a detachment or limit the damage if treatment starts early.
South Africa faces a particularly sharp burden from diabetes-related eye disease. Diabetic retinopathy is the country’s fourth leading cause of blindness, after cataracts, glaucoma and macular degeneration, according to the figures cited. Clinical screening data and regional studies suggest that as many as 40% of people living with diabetes have detectable diabetic retinopathy. In many cases, the condition is picked up through routine digital screening before symptoms develop, which is one reason eye-care experts continue to stress the value of regular examinations even when vision seems unchanged.
The challenge is that retinal disease often advances without warning. Symptoms such as blurred vision, dark patches or visual distortion may appear only after significant damage has already occurred. Alongside the warning from clinicians, patient groups are also using World Retina Week to emphasise support for people already living with sight loss. Retina South Africa has marked the week with the theme “Living Well with Sight Loss”, while Retina International has used the period to connect younger people with retinal conditions through its World Youth Conference, highlighting practical support, shared experience and the role of treatment, assistive technology and ongoing care in preserving independence.
