    Flow Velocity of Central
    Retinal Artery and Retrobulbar Vessels During
    Cardiovascular Operations.
     
    J
    Thorac Cardiovasc Surg 114: 1081-1087, 1997.

       

    It
    is imperative to monitor blood flow and blood
    pressure during cardiovascular surgery to avoid
    inadequate cerebral perfusion. 
    The current study assessed blood flow through
    the central retinal artery, which has been shown to
    reflect an obstruction of the carotid artery.

      

    Systolic
    B.P. was corelated with maximal velocity.
    The mean BP-axis intercept, or critical closing pressure, was 35.8mm
    Hg.

      

    Orbital
    vessel monitoring helps to establish the critical
    closing pressure of the central retinal artery and
    confirms patency of the circle of Willis.
    During cardiovascular oeprations, the eye can
    serve as “an acoustic window” to
    intracranial blood flow.
