Diabetic Macular Odema

What is Diabetic Macular Odema?

Diabetic macular odema is a common complication of diabetic retinopathy, occurring at any stage and is a leading cause of vision loss in patients with diabetes. It is caused by not only changes to the tiny blood vessels of the retina (the light sensitive layer at the back of the eye) but that it also involves glial cells (e.g. Muller cells) and neuronal cells with inflammation playing a significant role in its pathophysiology.

Vision loss occurs when the fluid reaches the macula (the centre of the retina that provides sharp vision) and builds up, causing swelling. A healthy macular is essential for good vision.
