The blood vessels may form scar tissue, which can pull on the retina causing a retinal detachment. A fluorescein angiogram is used to evaluate the retinal blood flow. Laser treatment is performed on those patients who develop neovascularization.
In the smallest blood vessels, capillaries and sinusoids, endothelium comprises the majority of the vessel. Blood vessel endothelium is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. Endothelial cells are derived from endothelial stem cells located in bone marrow.
