Diabetic eye disease refers to a group of conditions that can affect the retina, the part of your eye responsible for processing light and sending visual information to your brain. The most common of these is diabetic retinopathy, which occurs when elevated blood sugar damages the small blood vessels in the retina.
Over time, these changes can affect how well your eyes function, even if your vision seems stable. Because this process develops slowly, many patients are unaware of what is happening until the condition has progressed.
