If you have diabetes, controlling your blood sugar is important for a number of different reasons. Unfortunately, diabetics are more likely to contract a number of eye diseases; diabetic retinopathy is one of those diseases.
According to the American Optometric Association, diabetic retinopathy is caused by poor blood sugar regulation for an extended period of time. If your blood sugar is too high for an extended period of time, your vision can become blurred. This is due to the fact that high blood sugar causes there to be more liquid in your eye than usual. If your blood sugar comes back down fast enough, the blurriness usually goes away. However, if it stays too high for an extended period, then the blood vessels can become damaged and fail to nourish your retina, which is necessary for proper vision.
Many times, symptoms of diabetic retinopathy goes almost completely unnoticed. This makes it very important to get checked by a professional. Symptoms typically include blurry vision, floaters in your vision, colors lack their luster, dark spots, and vision loss.
If the disease is left unchecked and is not regulated, then very serious complications can occur such as retinal detachment. The eye can become so damaged and swollen that your retina may actually detach and complete vision loss can occur.
The treatment for this eye disease associated with diabetes depends much on its severity. Early on in diagnosis and the onset of the disease, the main focus will be to control your blood sugar properly. If you can get a good grip on your blood sugar, then the disease is very likely to slow, or completely stop, its progress.
However, at advanced stages of the disease, blood sugar regulation may not be enough. There are a few different kinds of laser eye surgeries that can be performed to correct the disease, but regular checkups and blood sugar control are still necessary.
