title: Orbital abscess from dacryocystitis caused by Morganella morganii.
abstract: A 22-year-old female with multiple developmental abnormalities stemming from cardiofaciocutaneous syndrome presented with a recurrent orbital abscess 2 years after orbitotomy with drainage of an abscess of presumed hematogenous-origin. During careful intraoperative examination the abscess was seen to directly extend from the lacrimal sac. Cultures were taken and grew Morganella morganii, a Gram negative rod uncommon in ocular and periocular infections. To the author's knowledge, this microorganism has been reported in only one previous case of orbital abscess and underscores the need for organism identification and antibiotic sensitivity analysis in cases of orbital abscess, particularly those with extension from dacryocystitis.
