Dayani and Grand1 performed 57 vitreoretinal surgeries in patients using warfarin sodium and having subtherapeutic (< 1.49 international normalized ratios), borderline (1.50-1.99 international normalized ratios), therapeutic (2.90-2.49 international normalized ratios), or highly therapeutic (> 2.50 international normalized ratios) values. Although postoperative hemorrhages developed in 2 eyes with subtherapeutic values and 2 eyes with therapeutic values, all cleared without treatment. Thus, Dayani and Grand concluded that vitreoretinal surgery is safe while maintaining anticoagulation therapy.
