Diabetes and eye health: Diabetic retinopathy Dr. David Greenman: So with diabetes initially when the blood sugars are high there is a little swelling on the lens of the eye and patients may have mild blurring vision, but they usually kind of keep going on they don't really pay attention to this. For the retinopathy, the retinopathy has to be very severe for patients to realize the at they even have it. Then there is two forms of retinopathy, there is proliferative form and pre-proliferative form. I mean the non-proliferative form patients get little hemorrhages in the retina that's the film in the camera that allows us to see. They have leaky blood vessels were cholesterol leaks out of the blood vessels hard as you take. They have swelling at the back of the eye they can take macular edema swelling at the 20-20 portion of the vision -- has been left out for two many seasons. The garden hose has gets little cracks along and if you putting that garden hose into a faucet and when we turn it on you see a lot of water leaking from the hose are along this cracks and that's kind of what the non-proliferative disease does it causes a lot of leakage from the blood vessels, which carrying nutrient to the eyes. In the proliferative form new blood vessels will actually grow, so you can think of this garden hose has being synched off. No blood gets through to the eye. And the eye tries to grow new blood vessels to carry nutrition to the eye how are these blood vessels are no good, they leak, they bleed they can fill the eye ball with blood and cause formation. Both of these diseases can exist simultaneously, we usually -- began with the non-proliferative disease. Usually it's a slow progress over time, so kind of slowly occurs due to uncontrolled blood sugars. How prevalent is diabetic retinopathy? Dr. David Greenman: My first presentation of -- being diagnosed with diabetes about 40-45% of those have diabetic retinopathy.
