Abstract
The eye serves as a mirror to the body vasculature. Changes in the retinal vasculature translate into the prediction of risk from cardiovascular disease. The mammalian retinal vasculature is the most widely used tissue to study physiological angiogenesis. Thus, the retinal vasculature plays a particular role in research linking various fields of expertise. Diabetic retinopathy is often cited as the paradigm for an angiogenic disease. However, there is much more to the diabetic eye, as the disease characteristics need to be considered to understand commonalities and differences f.e. to tumor angiogenesis. Primarily. diabetic retinopathy is vasoregressive in nature. Progressive capillary dropout drives sight-threatening proliferative diabetic retinopathy and macular edema by inflaming a hypoxic response. Although there is no animal model that qualitatively and quantitatively mimicks advanced human eye disease, they reflect the complex hyperglycemia-driven interaction of the neurovascular unit better than any in vitro systems. Downstream of high ambient glucose, multiple biochemical abnormalities exist which affect not only vascular cells of the capillary network but the entire neurovascular unit. Novel concepts that arise from tumor research can be useful to limit the neovascular of permeability-enhancing response to hypoxia in the diabetic retina.
