Intraocular hemorrhage is a common problem during vitreo-retinal surgery. Fortunately, severe bleeding is a rare occur-rence. In a series of 400 consecutive vitrectomies, Peyman et al 1 reported a 19% rate of intraoperative hemorrhage. Seventy-five percent of these were controlled with simple measures and the remaining 25% required cautery or diathermy to achieve hemostasis.
