Diabetic retinopathy is the result of damage to the tiny blood vessels that nourish the retina. They leak blood and other fluids that cause swelling of retinal tissue and clouding of vision. The condition usually affects both eyes.Diabetic retinopathy also known as diabetic eye disease, is when damage occurs to the retina due to diabetes. It can eventually lead to blindness. Diabetic retinopathy is the most common cause of vision loss among people with diabetes and a leading cause of blindness among working-age adults. Diabetic retinopathy can be treated with several therapies, used alone or in combination.
Diabetic retinopathy often has no early warning signs. Even macular edema, which can cause rapid vision loss, may not have any warning signs for some time. In general, however, a person with macular edema is likely to have blurred vision, making it hard to do things like read or drive. In some cases, the vision will get better or worse during the day. The other symptoms are:
•Seeing spots or floaters in your field of vision
•Having a dark or empty spot in the center of your vision
•Difficulty seeing well at night
Diabetic retinopathy is detected during an eye examination that includes following tests:
•Visual acuity test
