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.
Scarring can also cause high blood pressure in the vein that carries blood from the intestines through the liver (portal hypertension). This can lead to severe bleeding in the digestive tract and other serious problems. Cirrhosis can be deadly. But early treatment can help stop damage to the liver.
