Diabetic macular edema (DME) is a serious complication of diabetes that affects the retina, the light-sensitive tissue at the back of the eye. When high blood sugar levels damage blood vessels in the retina, they can leak fluid into the macula—the central part of the retina responsible for sharp vision. This swelling can blur or distort your vision, making everyday tasks like reading or driving difficult. Recognizing the symptoms and seeking timely treatment is crucial to preventing permanent vision loss.

Recognizing the Symptoms

The most common signs of diabetic macular edema include:

• Blurred or wavy vision: Straight lines may appear bent or distorted, and your central vision may become unclear.
• Colors appear faded: You might notice that colors look less vibrant than usual.
• Difficulty reading or recognizing faces: As the macula swells, tasks requiring detailed vision become challenging.
• Sudden vision changes: Some people experience a rapid decline in vision, while others notice gradual worsening over time.

If you have diabetes and experience any of these symptoms, it’s important to schedule an eye exam promptly. Early detection can help preserve your vision and prevent further damagemadeforthismoment.asahq.org.

What Causes Diabetic Macular Edema?

DME occurs when diabetes damages the tiny blood vessels in the retina, causing them to leak fluid into the macula. Poorly controlled blood sugar, high blood pressure, and high cholesterol increase the risk of developing DME. The longer you have diabetes, the higher your risk, especially if your blood sugar levels are consistently elevated.

How Is DME Treated?

Treatment for diabetic macular edema focuses on reducing swelling and preventing further vision loss. Common options include:

• Anti-VEGF injections: Medications like ranibizumab or aflibercept can block the growth of abnormal blood vessels and reduce fluid leakage.
• Steroid injections or implants: These help reduce inflammation and swelling in the retina.
• Laser therapy: Targeted laser treatment can seal leaking blood vessels and slow the progression of the disease.
• Managing diabetes: Controlling blood sugar, blood pressure, and cholesterol levels is essential to protect your vision and overall health.

The Importance of Regular Eye Exams

If you have diabetes, regular eye exams are critical for detecting DME early. Your ophthalmologist can monitor changes in your retina and recommend treatment before symptoms worsen. Even if your vision seems fine, annual eye exams are essential, as DME can develop without noticeable symptoms in its early stages.

Lifestyle Changes to Protect Your Vision

In addition to medical treatments, managing your diabetes effectively can help prevent or slow the progression of DME. Maintain a healthy diet, exercise regularly, and follow your doctor’s recommendations for blood sugar control. Quitting smoking and managing blood pressure and cholesterol levels can also reduce your risk of complications.
