Dark spots in your vision
Diabetes can have a serious impact on your vision, even causing blindness. Diabetic retinopathy, a condition where the retina’s blood vessels are damaged by high blood glucose levels, is one of the most common causes of blindness in adults.
In the early stage of diabetic retinopathy, there may be no obvious symptoms. As the condition advances, the retina begins to grow new blood vessels that aren’t as strong, and these vessels may bleed, causing the dark spots in your vision.
Since there may not be any noticeable symptoms in the early stage of diabetic retinopathy, it is vital to keep up with annual visits to the eye doctor to detect any possible problems.
