摘要：

Background: Ocular complications during cardiopulmonary bypass (CPB) are common, and one reason could be increased intraocular pressure (IOP). Methods: We measured IOP with a Perkins applanation tonometer in 20 patients having elective coronary artery bypass graft surgery with CPB. Results: IOP increased when CPB was started (p<0. 001), and was maintained for 20 minutes, with a gradual return to pre-CPB values at 40 minutes. At the same time mean arterial pressure and haematocrit values decreased (p<0. 001). Conclusion: Haemodilution caused by the infusion of pump prime could increase ocular blood flow and IOP. © 2005 Indian Association of Cardiovascular-Thoracic Surgeons.
