A statistical clinical description of diabetic retinopathy
Diabetic Retinopathy is a microvascular abnormality of the retinal circulation. It is usually seen in patients who have other ocular abnormalities, including glaucoma and cataract. The retinal manifestations represent the most common disorder of the macula, leading to severe vision loss in people under the age of fifty.
There are two forms of diabetes, including non-proliferative retinopathy which affects the micro circulation of the retina with abnormalities leading to permeability of leakage as well as ischemia or a closure of capillaries. These changes may progress to involve a proliferating of abnormalities known as proliferative diabetic retinopathy.
Hemorrhages into as well in front of the retina involving the vitreous may occur, leading to tractional pooling of the retina with breaks in its continuity as well as detachments. Ultimately, a fibrosis may evolve, necessitating surgery that may control or even reverse some of the damaging effects of the abnormal vessels.
