About CSME

Clinically Significant Macular Edema (CSME) is a chronic eye disease associated with diabetes and can result in progressive degradation of fine, detailed vision.

Changes in lifestyle and diet, and increases in obesity and life expectancy rates, have led to a marked increase in the incidence of diabetes-related eye disease. All people with diabetes have a risk of developing CSME over time. On average, CSME affects 30% of people who have suffered from diabetes for a period of 20 years or more.

CSME can be diagnosed with a simple eye examination. Detecting changes early through regular check-ups with your optometrist or ophthalmologist can identify the disease before sight-threatening complications occur.

What causes CSME?

Clinically Significant Macular Edema (CSME) is a form of Diabetic Retinopathy (diabetic eye disease) and results in the swelling of the central retina (back part of the eye). This central swelling, also known as Macular Edema, occurs when small blood vessels in the macula (center part of retina) leak fluid. CSME is chronic and degradation of fine, detailed vision can occur at any stage of the disease.

In order to preserve vision and prevent progression of CSME, it is important to take control of your blood sugar levels, blood pressure, and blood cholesterol.

Some of the factors that may put you at higher risk for CSME include:

  • Duration of diabetes — the longer you have diabetes, the greater your risk of CSME
  • Poor control of your blood sugar level
  • High blood pressure
  • High cholesterol
  • Smoking
What is the retina?

The retina is the light-sensitive nerve tissue at the back of the eye that converts light images from the environment into electrical impulses that are processed and sent along the optic nerve to the brain.

What is the macula?

The macula is the small, critical central area of the retina responsible for acute, detailed central vision.

What is edema?

Edema is a condition characterized by swelling caused by excess fluid leaking, and collecting in the cavities or tissues of the body.

In its early stages, CSME can have little or no effect on your vision. As the condition continues, fine, detailed vision can be affected and progressively deteriorates. If left untreated vision may be permanently lost and can result in legal blindness.
