A vitrectomy [58] is a technique in which the vitreous is surgically removed along with removal of the posterior hyaloid.

Some studies have shown that a vitrectomy may be beneficial for macular edema due to CRVO. One theory is that a vitrectomy may relieve traction on the macula and, thus, reduce macular edema. According to another hypothesis, removing the vitreous will also remove cytokines and VEGF associated with a venous occlusive event; thus, the stimulus for macular edema will be reduced.

At the present time, no convincing evidence indicates that a vitrectomy is the best approach.
