Information for healthcare professionals about diabetic macular oedema.

Diabetic macular oedema (DMO) is a complication of diabetes that occurs when there is damage to the blood-retinal barrier, leading to accumulation of fluid within the intraretinal layers of the macular.1

Hyperglycaemia caused by uncontrolled diabetes can, over time, lead to serious damage to body systems, particularly nerves and blood vessels.2

Worldwide, diabetes is one of the leading causes of2:




Heart attack and stroke






Kidney failure



Lower-limb amputation


DMO is a complication of diabetic retinopathy. It can occur at any stage of diabetic retinopathy, although it is more likely to occur the longer the disease goes on.3

Approximately 7% of people with diabetes have DMO.4
