title: Listeria monocytogenes-induced endogenous endophthalmitis: bioultrasonic findings.
abstract: OBJECTIVE
  To report bioultrasonic findings in Listeria monocytogenes-induced endophthalmitis (LMIE) that have not been described previously.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  To rule out intraocular tumor, ultrasound biomicroscopy was performed in a patient referred for a 2-day history of uveitis with elevated intraocular pressure, dark hypopyon, and pigment dispersion in the anterior chamber.
  
  
  RESULTS
  Ultrasound biomicroscopy examination showed increased iris thickness with rarefaction of tissue and irregular echogenicity as well as iris pigment epithelial detachment. A small choroidal detachment was also detected. The anterior chamber and vitreous sample confirmed the LMIE diagnosis.
  
  
  CONCLUSIONS
  The detection of both pigment epithelial detachment and changes in the iris tissue could explain why black hypopyon frequently develops in LMIE with significant pigment dispersion in some cases.
