Prevalence of diabetes mellitus is increasing worldwide especially in developing countries. Foot ulcerations in patients with diabetic neuropathy have a high impact in the overall amputation rate. In the present study we looked for the severity of diabetic retinopathy in patients with diabetic foot syndrome in a diabetic care unit in a sub-Sahara megacity (Kinshasa, Democratic Republic of Congo).
Forty one patients with diabetic related foot ulcerations (26 male, 15 female, mean age 45,6 years) were enrolled in the study. All patients underwent visual acuity evaluation and slit lamp biomicroscopy. Incidence and stage of retinopathy were evaluated by retinal funduscopy and documented by fundus photography.
Twenty seven eyes showed no signs of diabetic retinopathy. Forty seven eyes were diagnosed as non proliferative diabetic retinopathy (16 mild, 16 moderate, 15 severe). Seven eyes showed proliferative diabetic retinopathy. One patient had a unilateral central venous occlusion. In this case the classification of diabetic retinopathy was not possible because of the massive retinal bleedings.
It was evident that there is a considerable discrepancy between partly extensive foot ulcerations and only mild to moderate diabetic retinopathy in most of the patients. This indicates neuropathy induced foot problems and microangiopathy induced diabetic retinopathy are diabetic complications whose formal pathogenesis is only loosely correlated. Additional risk factors in local African conditions compared to Europe may play a major role in this discrepancy.
