An unusual case of orbital abscess due to Morganella morganii and Klebsiella pneumoniae, following acute on chronic dacryocystitis

Orbital abscess secondary to dacryocystitis is rare.[1]Morganella morganii is a gram-negative rod and a facultative anaerobic enteric bacterium causing opportunistic infection, often isolated as a cause of nosocomial infection, specifically in urinary tract or wound infections. Risk factors may be old age, presence of concomitant bacteremia, hospitalization, recent surgery, concurrent antibiotic use, and immunocompromised hosts.[2] According to authors' knowledge, till date, only one case of orbital abscess due to M. morganii has been reported secondary to sinusitis. There are no reports of orbital abscess due to M. morganii following dacryocystitis till date.[3] We report a rare case of orbital abscess secondary to dacrocystitis caused by M. morganii and Klebsiella pneumoniae in an immunocompetent patient.
