| Outline of Final Research Achievements |
Laser speckle flowgraphy (LSFG) device is popular in the field of Opthalmolgy because its ability to estimate ocular blood flow in awake condition. This study was designed to evaluate the feasibility of LSFG for monitoring ocular perfusion in various conditions including before cardiopulmonary bypass (CPB), during CBP, during CPB with selective cerebral perfusion (SCP) under hypothermia and after CPB. The results showed LSFG was able to record intraoperative ocular perfusion with high reproducibility and succeeded in identification of intraoperative changes in ocular perfusion. The results in this study showed intraoperative measurement of optic nerve head blood flow using LSFG can be used as additional cerebral perfusion monitor for radial arterial blood pressure during aortic arch surgery with CPB and SCP.
