Diabetic retinopathy is an eye disease developed in all kind of diabetic people in which retina will be damaged due to diabetes causing blindness.
There are two stages of diabetic retinopathy.
Usually there is no early signs in diabetic retinopathy . Sometimes even macular edema, which can cause rapid vision loss, may not have any warning signs. However, a person with macular edema will 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. Typical symptoms of retinopathy may include one or more of the following signs.
Methods of eye examination that detect diabetic retinopathy includes:
Visual accuracy test:
Different eye chart is used to measure how well a person sees or read at various distances.
Eye drops will be dropped in the eye to dilate the pupil, so that the retina can be closely examined for the sign of diabetic retinopathy. Close-up vision may remain blurred for several hours after this test.
A fluoresce that is a Yellow dye is injected into a vein, usually in your arm. The dye travels through your blood vessels and a special camera takes photos of the retina as the dye travels throughout its blood vessels. This shows if any blood vessels are blocked or leaking fluid. It also shows if any abnormal blood vessels are growing.
This is another way to look closely at the retina. A machine scans the retina and provides detailed images of its thickness, which will help measure swelling of your macula.
Treatment options may include:
Controlling your blood sugar and blood pressure keeps your eye's blood vessels healthy. Hence can reduce the risk of vision loss.
