Diabetic RetinopathyDiabetic retinopathy is retinopathy (damage to the retina ) caused by complications of diabetes mellitus, that could ultimately lead to blindness. "Retinopathy" is the medical term for detriment to the tiny blood vessels (capillaries) that nourish the retina, the tissue at the back of your eye which captures light and relays information to your brain. Deplorably, patients who are not properly referred for evaluation and management or those who, for any reason, fail to get proper care from an ophthalmologist, are at the greatest risk of vision loss. Findings in the retina comprise dot and blot hemorrhages (tiny hemorrhages in the retina itself), microaneurysms (out-pouchings of capillaries), and exudates (retinal accumulations occurring as a result of leaky vessels). This is known as retinal detachment, and it can result to blindness if untreated. In addition, abnormal blood vessels can grow on the iris, which can lead to glaucoma. In this phase, the arteries in the retina become enfeebled and leak, forming small, dot-like hemorrhages. Blood may leak into the retina and vitreous, resulting spots or floaters , along with decreased vision. You can take steps to ward your sight if you have diabetes. These comprise a yearly eye examination and steps to keep your blood sugar, blood pressure and blood cholesterol under the best possible control. This scar tissue cringes and may pull on the retina, creating a form of retinal detachment called "traction retinal detachment". This bleeding can also cause scar tissue to develop, that can pull on the retina and cause the retina to detach from the wall of the eye ( retinal detachment ). Ophthalmologists may endorse treatment at this stage, especially if the opposite eye has had diabetic related complications. Diabetes is a disease which occurs when the pancreas does not produce enough insulin or the body is unable to process it properly. Approximately half of people with known diabetes have some degree of diabetic retinopathy. An outstanding amount of research has already been completed, and is relied upon heavily by practicing ophthalmologists, in the treatment of patients with diabetes. The development of this condition in type I (juvenile-onset) diabetics is rarely present precedent to three or four years following the onset of diabetes. The blocked vessels may also divest parts of the retina of adequate oxygen, and this too contributes to a disturbance in the retina's ability to process images. The new blood vessels can cause scar tissue to develop, that can pull the retina away from the back of the eye. This may be yoked with a fundus fluorescein angiography, a test done to assess the extent and type of changes in the retina and its blood vessels. One of the important reasons for formulaic eye examinations is that if new vessel formation is detected early, it may be treated effectively and the dangerous vessels dispersed by applying multiple laser burns to the periphery (outside edges) of the retina.
