Summary: Diabetic retinopathy is a chronic complication of diabetes affecting small vessels of the retina. It leads to vision deterioration and in advanced cases to loss of vision. Duration of diabetes and chronic hyperglycemia are the main factors responsible for microangiopathy development. Although factors predisposing to vascular lesions are known, the pathomechanism of retinopathy has not been elucidated. Morphological and circulatory disorders in the retinal vessels were observed in early stages of diabetes, but their impact on the development of further complications of diabetic retinopathy is unknown.
Disorders in morphology and circulation in the retinal vessels were already observed in the early stages of diabetes before clinical signs of diabetic retinopathy occurrence. There is more evidence that changes in the retinal nerve layers precede microangiopathy.
