Progression of diabetic retinopathy

In the nonproliferative stage of diabetic retinopathy, there may be no symptoms if the problem is mild. But as the problem becomes more severe, the central part of the retina may swell, leading to macular edema, which causes a noticeable decline in central vision.

An eye exam can detect even the earliest changes, such as

• leaking blood vessels

• retinal swelling (macular edema)

• fatty deposits on the retina

• damaged nerve tissue

• other changes in the blood vessels.

Early swelling in particular may produce a noticeable reduction in vision.

As diabetic retinopathy progresses to its later stage, proliferative retinopathy, symptoms become more dramatic. You might notice spots that are really specks of blood floating in your vision. Although sometimes the specks will clear without treatment, hemorrhaging can occur repeatedly, often during sleep. Seek treatment immediately from an eye care professional if you notice specks obscuring your vision. Otherwise, bleeding may become more severe, and vision loss and blindness can occur. The sooner you get help, the better, as earlier treatment is more likely to be effective.
