One of the ways diabetes effects the eye is called “diabetic macular edema”, or DME. All patients with diabetes are at risk of developing DME. The onset is usually insidious and painless, and manifests with blurring of central visual acuity. The effects may range from mild and asymptomatic to profound loss of vision.
Studies suggest DME may affect up to 7 % of people with diabetes, and that number increases with the number of years the person is diabetic, and how well the patient has managed their deabetes.
