Purpose: To estimate the risk of hemorrhagic complications associated with 25-gauge pars plana vitrectomy (PPV) when warfarin (Coumadin; Bristol-Myers Squibb, New York, NY) or clopidogrel (Plavix; Bristol-Myers Squibb) are continued throughout the surgical period, as compared with a control group.

Design: A single-center, retrospective, cohort study of 289 consecutive patients receiving either warfarin therapy or clopidogrel therapy or neither of those therapies who underwent 25-gauge PPV.

Participants: Included were 61 patients (64 eyes; 64 PPV procedures) in the warfarin group and 118 (125 eyes; 136 PPV procedures) in the clopidogrel group.
