Diabetic Retinopathy

 The retina is the inside layer of the eye. It's part of the AR that's most important for transmitting light into vision. 

Diabetes affects essentially blood vessels in the eye and the rest of the body and it affects blood vessels in essentially two ways: 

One way is it causes blood vessels to close down and blood vessels normally carry blood to various parts of the body and when the blood vessels closed down the eye as the rest of the body responds to that by creating new blood vessels and new blood vessels in the majority of the body are a good thing in that circumstance but in the eye, they are not such a good thing because there's new blood vessels over friable and more likely to bleed and the eye needs clarity in the middle to allow light to transmit to it. 

The second way that it affects the blood vessels is it causes the blood vessels to leak and leaking from the blood vessels can damage the retina which as I mentioned that the inside part of the eye that's responsible for transmitting light into vision and if you get leakage in that area particularly the central part of the retina that can significantly affect vision. 

What are the symptoms of diabetic retinopathy? 

  Diabetic retinopathy can be a very slow-moving insidious condition because it develops and progresses so slowly. The changes that might occur in diabetic retinopathy occur over a long period of time there may be no symptoms at all.  As the disease gets worse can eventually lead to poor vision. However in the majority of cases with diabetic retinopathy usually no symptoms the patient may perceive certainly in the earlier stage of the disease. As the disease gets worse the symptoms may and the diabetes rabbit and retinopathy gets worse the patient may actually lose the vision that eye sometimes irreversibly but because for the majority of the disease process the patient may not have any symptoms or any effected vision. Patients may be unaware of the fact that they have diabetic retinopathy and is therefore very important that they get seen regularly by an eye specialist to monitor their disease process in the eye. 

How does diabetes cause blurry vision?

 Diabetes most of the time causes very little symptoms for the patient until the disease progresses unchecked for some period of time the blood vessels that are affected primarily by diabetes canshut down or they can leak if. If they shut down how the body responds to that is by creating new blood vessels to carry blood to the areas that are affected by the die be hit by the shutdown blood vessels in the rest of the body that is a useful thing but in the eye which depends on the eye being clear. These new blood vessels can bleed.
