Orbital apex syndrome due to invasive aspergillosis in an immunocompetent patient

Infection is a rare cause of orbital apex syndrome (OAS) and most commonly occurs in immunocompromised hosts. We report a case of OAS in an elderly immunocompetent female due to invasive aspergillosis and Staphylococcus aureus co-infection. The patient required both surgical debridement and prolonged courses of antibiotic and antifungal therapy. Invasive fungal disease must be considered in cases of OAS, even in patients without classic risk factors
