What is Diabetic Macular Edema?

Diabetic macular edema (DME) is the accumulation of fluid, or swelling, in the macula-the central part of the retina that is responsible for our sharpest central vision.

The main symptom of DME is decreased vision, and because there are other causes of decreased vision in diabetics, an examination by an ophthalmologist is the only way to determine if a particular person has macular edema. This vision loss may limit or prevent daily activities such as driving.

Many physicians believe that high blood pressure, abnormal kidney function causing fluid retention, high cholesterol levels, and other general systemic factors may contribute to the problem of diabetic macular edema. It is therefore important to control or monitor blood pressure, kidney function, cholesterol levels, and blood sugar levels to help control macular edema long term.

Laser treatment is useful for some patients with diabetic macular edema.

Diabetic macular edema is a complex problem that requires understanding, and continued observation and care under the guidance of your ophthalmologist.
