A recent review of 11 randomized clinical trials suggested a structural, and potentially functional superiority of vitrectomy over observation at 6 months. Vitrectomy was superior to laser in terms of structural outcomes at 6 months, but this advantage was lost at 12 months. Overall, there was little evidence to support the use of vitrectomy in DME in the absence of epiretinal membrane (a proliferative fibrocellular tissue found on the inner surface of the retina) or vitreomacular traction.
