The condition and the treatment
Diabetic macular oedema affects sight in people with diabetes.The macula is the central part of the retina at the back of the eye. Oedema is a build up of fluid. In diabetic macular oedema, there is abnormal growth of new blood vessels in the macula. These vessels leak fluid, causing the macula to swell and become thicker, leading to problems with sight.
Aflibercept (Eylea) is given by injection into the eye. It works by blocking a substance that stimulates the abnormal growth of blood vessels in the macula.
