Researchers alternatively assigned 39 consecutive patients (41 eyes) undergoing primary pars plana vitrectomy with silicone oil tamponade to receive one Avastin injection one week before surgery or no pretreatment. In the Avastin group, intra- and postoperative bleeding was significantly less, as was blood reabsorption time (11.1 vs. 34.8 days). BCVA improvement was significantly greater. However, subretinal bleeding was significantly more common in the Avastin group (nine cases vs. one). Retina, June 2009
