Endogenous Endophthalmitis: Etiology and Treatment

Abstract

This chapter comprehensively covers all aspects of endogenous endophthalmitis from systemic infectious agents, with an emphasis on reported and newer etiologies to broaden the diagnostic and investigative acumen of treating ophthalmic providers. The discussion includes the etiology of metastatic endophthalmitis and diagnostic investigations, including polymerase chain reaction (PCR), for identification of bacterial and viral infections involving the eye in both immunosuppressed in non-immunosuppressed patients. Additionally, we present clinical and diagnostic findings of fungal infections, protozoal infections, and helminthic infections. Pediatric cases are also reported and etiologies described. We discuss both etiology and diagnostic challenges. Current therapeutic modalities and outcomes are reviewed. While no two cases of metastatic endophthalmitis are the same, some similarities may exist that allow us to generalize how to approach and treat this potentially sight- and life-threatening spectrum of diseases and find the underlying systemic cause.
