Background:
Diabetes 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.
Methods:
We 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.
Results:
Diabetic 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.
Conclusion:
We concluded that a regular ophthalmologic follow up is necessary for early diabetic retinopathy detection and treatment.
