title: [An analysis of the cause of misdiagnosis with ocular opportunistic infection].
abstract: OBJECTIVE
  To evaluate the causes of misdiagnosis with ocular opportunistic infection.
  
  
  METHODS
  The causes of misdiagnosis on 4 cases (6 eyes) with ocular opportunistic infection were analyzed.
  
  
  RESULTS
  Acanthoamoeba keratitis was misdiagnosed as herpes simplex keratitis and fungal keratitis in 1 case (1 eye). Propionibacterium acne endophthalmitis was misdiagnosed as exogenous fungal keratitis in 1 case (1 eye). Endogenous fungal endophthalmitis was misdiagnosed as metastatic choroid cancer from lung in 1 case (2 eyes). Cytomegalovirus retinitis was misdiagnosed as endogenous fungal endophthalmitis in 1 case (2 eyes).
  
  
  CONCLUSIONS
  If common therapies are of no effect with some ocular infections and the causative organisms responsible for the infection could not be found out after repeated tests, the rare ocular opportunistic infection should be considered. Special examinations (such as acanthoamoeba culture, anaerobic culture, fungus blood culture, cytomegalovirus serological assays, etc.) should be made for a definite diagnosis.
