Retinopathy

In diabetic retinopathy, the blood vessels in the retina become abnormal which may cause problems with your vision. Normally, the blood vessels in the retina do not leak. In diabetic retinopathy, the retinal blood vessels develop tiny leaks. These leaks cause fluid or blood to seep into the retina. Fatty materials, called exudates deposit in the retina. When these problems occur in the central part of the retina vision will be reduced or blurred. Leakage elsewhere in the retina will usually have no effect on vision.
