Demystifying Diabetic Eye Disease | Diabetic Eye Disease Awareness Month

November is Diabetic Eye Disease Awareness Month, which highlights the need for education, early detection, and proper management of diabetes and diabetic eye diseases.

Continuing reading for an understanding of how diabetes affects your vision and eye health and what proactive steps you can take.
​

Diabetic eye disease is more than one condition. Rather, it is the umbrella term used to describe eye problems that may develop as a complication of diabetes. These diseases include:

Diabetic retinopathy: Over time, high blood sugar levels can damage the blood vessels in the retina. The blood vessels may leak or grow abnormally. This leads to changes in vision and potentially vision loss. It is the most common eye disease related to diabetes.

Diabetic macular edema (DME): DME involves swelling of the macula, which is the central part of the retina that helps us have sharp vision

Cataracts: Cataracts involve clouding in the eye’s lens, which helps focus light into the retina. Although cataracts can also develop in people without diabetes, individuals with diabetes are two to five times more likely to develop them than those without the condition.

Glaucoma: Glaucoma is a condition that causes damage to the optic nerve and gradual loss of vision. Having diabetes increases your risk of developing glaucoma.
​

Individuals who have chronically high blood sugar levels may sustain damage to the blood vessels throughout their body, including the vessels in the eyes. Significant fluctuations in blood sugar levels may also cause the lens of the eye to swell, which contributes to potential eye changes.

There are often no noticeable symptoms in the early stages of diabetic eye diseases. However, as the disease progresses, symptoms may include:

• Blurry vision
• Floaters or dark spots
• Problems seeing at night
• Colors appearing faded
• Blank or dark areas in your field of vision

​

Although there may be no apparent symptoms in the early stages of diabetic eye diseases, they can be diagnosed through a comprehensive dilated eye exam. Even if your vision appears fine, an eye exam can help spot early changes that have developed.

Although it may vary, the American Diabetes Association usually recommends a comprehensive eye exam yearly for individuals with diabetes; however, your doctor may suggest more frequent eye exams depending on your specific needs.
​

Depending on your specific eye disease and its severity, your eye care specialist may recommend the following:

• Good blood sugar control: This includes tight monitoring of your blood sugar to maintain appropriate levels, which can slow damage progression.
• Laser therapy: Laser therapy helps reduce abnormal blood vessels.
• Anti-VEGF injections: This involve injections to help prevent the growth of abnormal blood vessels in the retina and reduce swelling.
• Vitrectomy surgery: In advanced eye disease, surgery may be helpful to remove blood or scar tissue from the eye.

​

Although you may not always be able to prevent diabetes or diabetic eye diseases, there are several steps you can take to lower your risk of developing vision complications, such as those listed below.

• Keep your blood sugar in target range as directed by your doctor.
• Get regular exercise.
• Monitor and control blood pressure levels.
• Avoid smoking.
• Immediately tell your eye doctor about vision changes.
• Don’t skip regular eye exams.

Remember, diabetes doesn’t mean you will go on to develop diabetic eye diseases. With comprehensive eye exams, early detection, good blood sugar control, and healthy lifestyle choices, you can protect your vision and your overall quality of life.
