The treatment paradigms for the treatment of DME are rapidly evolving. Vascular endothelial growth factor (VEGF) has been shown to play a central role in DME. This has driven research efforts for the development of several agents that block the actions of VEGF in the retina. Anti-VEGF treatment represents a major advance in the management of DME.
