The most common diabetic eye disease is Diabetic Retinopathy. It is also the No. 1 cause of blindness among North Americans. It occurs when there are changes in the retina's blood vessels. Often, people experience swollen blood vessels and fluid leaking out of their eyes, while some others experience have abnormal blood vessel growths on the retina surface.
If you are diagnosed with diabetic retinopathy, you may not notice any vision changes initially, but with time, as this condition worsens and you experience vision loss, it will become apparent to you. Usually, diabetic retinopathy affects both eyes.
