Early complications of diabetic retinopathy include blurry vision and difficulty reading and recognizing faces. As new blood vessels grow and leak fluid into the eye, the vitreous humor can be overcome, causing temporary vision impairment. Advanced stages of diabetic retinopathy can place pressure on the optic nerve and pull on the retina, causing this structure to detach from the back of the eye. These complications can result in vision loss. Finally, diabetic retinopathy is associated with an increased risk for other eye diseases such as glaucoma.
