What causes diabetic retinopathy?

No-proliferative diabetic retinopathy (NPDR) is the early condition of your disease through which symptoms will likely be gentle or no-existent. In NPDR, the blood vessels in the retina are weakened triggering tiny bulges called microanuerysms to protrude off their surfaces.

Proliferative diabetic retinopathy (PDR) is definitely the more advanced form of the disease. At this stage, new fragile blood vessels can begin to grow from the retina and into the vitreous, the gel-like water that fulfills the back of the eyes. The newest blood vessel may leak blood in to the vitreous, clouding vision.

Diabetic retinopathy is a result of the damage diabetes causes for the small blood vessels found in the retina. These damaged blood vessels might cause vision loss:

Substance can leak into the macula, the area of the retina accountable for obvious central vision. Although small, the macula may be the part of the retina that allows us to see colors and fine fine detail. The liquid causes the macula to swell, causing blurred vision.

In an attempt to boost blood circulation within the retina, new blood vessels might form on its work surface. These fragile, abnormal blood vessels can leak blood into the back from the eyesight and obstruct vision.
