Now days, Diabetes Mellitus is one of the most common disease in all over the world. Moreover, diabetic retinopathy is an

eye diseases connected with diabetes is considered to be the most ordinary causes of blindness. An individual suffering from diabetes requires having regular eye examinations because vision loss due to diabetic eye disease can be prevented.

Diabetes roots the sugar levels in the blood to raise causing harm to the blood vessels of the organs in the body. Injure to the blood vessels of the nerves can outcome to neuropathy. Injure to blood vessels of the kidney can end result to kidney failure therefore requiring dialysis. Furthermore, high glucose levels in the blood can also spoil the retina’s blood vessels. The retina is simply like a film within a camera that lines the reverse of the eye and detects light that incoming the eye and

transforms it into a picture for the brain to take. While the blood vessels of the retina becomes damaged, the retina may discontinue functioning thus vision defeat becomes evident.

Persons, who have been showing to high levels of sugar for a very long time like in diabetes, can root portions of the blood vessels in the retina to deteriorate. These weakened portions generally pouch out next to the walls of the blood vessels forming microaneurysms. These microaneurysms can come apart anytime, spilling blood into the retina and are seen as small dots of hemorrhages where the majority of it will vanish over time and the remaining debris will figure clumps called hard exudates.

Overall, these changes in the retina of the eyes can be known as background diabetic eye disease. This disease is relatively common among known diabetics for ten years or more. Background diabetic eye disease hardly ever causes major loss of vision if not the macula, which is the center of the retina, is affected. When the swelling happens in the macula, it is named as diabetic macular swelling, in which vision loss is likely an outcome.
