The age range of cases reported was 0-78 years, and male sex was predominant in studies where these parameters were reported. The most common causative agent was Our review highlights the importance of recognizing the infections triggering Miller Fisher syndrome. We also present a unique case of Miller Fisher syndrome associated with breakthrough varicella zoster virus infection.
