title: Multiple evanescent white dot syndrome after hepatitis B vaccine.
abstract: OBJECTIVE
  Hepatitis B vaccine has become an effective means of preventing complications of hepatitis B. However, it occasionally induces serious side effects. We report a case of multiple evanescent white dot syndrome (MEWDS) that occurred following hepatitis B vaccination.
  
  
  METHODS
  A 23-year-old woman with a one-week history of progressive loss of vision in the left eye and bilateral photopsia was referred for examination. Her symptoms appeared 24 hours after a booster intramuscular injection of hepatitis B vaccine.
  
  
  RESULTS
  Clinical examination, fluorescein angiography, and the course of events were typical of MEWDS.
  
  
  CONCLUSIONS
  This case demonstrates the occasional occurrence of MEWDS after hepatitis B vaccine and suggests that hepatitis B virus immunization may be a risk factor for this retinal condition.
