Diabetic macular oedema (DMO) is currently the main complication associated with diabetes. The percentage of patients with DMO grows alongside the increasing number of diabetes occurrences. The DMO treatment has seen major developments in the past few years. A number of new treatment technologies have emerged, which enable not only a stabilisation of macular oedema but in the case of an early detection also a decrease of retina oedema accompanied by a visual functions improvement. Laser coagulation has remained the standard DMO treatment for many years; when applying modern diagnostic testing technologies (FAG and OCT), the newest trend in DMO treatment is the use of anti-VEGF preparations, depot intravitreal corticoids and in some cases also surgical intervention in the form of pars plana vitrectomy (PPV). The DMO treatment algorithm is presented in this paper.
