Marcus-gunn phenomenon with- mitral valve prolapse

Marcus-gunn phenomenon is a congenital and sometimes hereditary anomaly, in which a ptotic eyelid retracts momentarily when the mouth is open, or the jaw is moved. These associated movements attributed to abnormal connections between the central mechanisms innervating the pterygoid and elevator muscles. Sometimes this anomaly is associated with dual,s retraction syndrome, duplex kindneys and ureters. This case is a report of an association between mitral valve prolapse and marcus-gunn phenomenon.
