BackgroundDiabetes is one of the principal cause of blindness in adults. The aim of the study is to evaluate the frequency of ocular complications and risk factors of diabetes. It's a multicentric prospective study on a representative sample of 285 diabetics.MethodsWe performed a general and an ophthalmologic exam for all patients with retinal angiography and appropriate laboratory tests. Chi 2, Fisher, Mann and Whitney tests were used as statistical methods.ResultsDiabetic retinopathy was observed in 45,2% of patients, cataract in 22%, glaucoma in 5%. Diabetic retinopathy frequency rises especially with duration of diabetes and bad glycaemic control. Blindness related to diabetic retinopathy was observed in 6,25% and visual deficiency in 12,5%. The authors compared their results with literature data. They emphasize on the great value of regular better glycaemic control and other associated metabolic disorders.ConclusionWe concluded that a regular ophthalmologic follow up is necessary for early diabetic retinopathy detection and treatment.
