Abstrait
In patients with diabetic retinopathy, elevated serum levels of total circulating insulin-like growth factor-I (IGF-I) have been implicated as an important mediator of the disease. There is no study, however, measuring free IGF-I levels in patients with diabetic retinopathy which mediate the biological effects of IGF-I and are modulated by a complex system of six specific IGF binding proteins (IGFBPs) and several IGFBP proteases.
