Diabetic Eye Disease is actually a group of eye conditions that can affect people with diabetes. These include diabetic retinopathy, diabetic macular edema (DME), cataract, and glaucoma. All of these conditions can potentially lead to severe vision loss or even blindness.
Diabetic Retinopathy is the most common cause of vision loss in people with diabetes and is the leading cause of visual impairment and blindness in working-age adults. Diabetic retinopathy occurs when chronically high blood sugar from diabetes damages the blood vessels in the retina causing them to hemorrhage or leak fluid, thus distorting vision. In its advanced stages, new abnormal blood vessels will grow on the surface of the retina and can lead to scarring and cell loss. Diabetic retinopathy can also lead to diabetic macular edema.
Diabetic Macular Edema (DME) occurs when fluid builds up (edema) in a part of the retina called the macula. The macula is responsible for the sharp, straight-ahead vision you use to recognize faces, read or drive. DME is the leading cause of vision loss in people with diabetic retinopathy. DME can happen at any stage of diabetic retinopathy and will affect about half of all people with the disease.
People with all types of diabetes are at risk for developing diabetic retinopathy, and the risk increases the longer a person has diabetes. Of all Americans diagnosed with diabetes, 40 to 45 percent have some degree of diabetic retinopathy, but only about half of those are aware of it.
Diabetic retinopathy will often go unnoticed until it begins affecting vision because in its early stages there are usually no symptoms. When bleeding from abnormal blood vessels in the retina eventually occurs it can cause the appearance of spots or floaters. At that point, without prompt treatment, you increase your risk for DME and permanent vision loss. That is why it is so crucial for diabetic patients to have comprehensive dilated eye exams at least once a year.
Diabetic Retinopathy Symptoms
- Blurred vision
- Spots or floaters
- Difficulty distinguishing colors
- Difficulty with night vision
Cataracts are also a big problem for patients with diabetes. A cataract is a clouding of the natural lens in the eye. Cataracts are most often associated with age but tend to develop earlier in people with diabetes. Adults with diabetes are 2 to 5 times more likely to develop a cataract than those without diabetes. Early cataracts can be treated with corrective lenses, but when cataracts begin to interfere with vision the cataract surgery will be required.

Glaucoma is the leading cause of blindness in the U.S. and refers to a group of disorders associated with abnormally high intraocular pressure that can cause damage to the optic nerve, the bundle of nerve fibers that connects the eye to the brain. For adults with diabetes, their risk of developing glaucoma is nearly doubled. As with diabetic retinopathy, the onset is so gradual that it can easily go unnoticed until it reaches its advanced stages and permanent damage has already been done. For patients with diabetes, it is especially important to have regular visits with an ophthalmologist. Symptoms to watch out for include:
- Gradual loss of peripheral vision
- Eye pain (possible accompanied with nausea or vomiting)
- Blurred vision
