title: Mass photokeratitis following ultraviolet light exposure at a nightclub.
abstract: OBJECTIVE
  To report a mass presentation of photokeratitis arising from exposure to an unprotected ultraviolet-B (UV-B) light source.
  
  
  RESULTS
  A cluster of 22 patients presented within a 24-h period to a single eye casualty with symptoms of photokeratitis following recent intense UV-B exposure at a local nightclub. Patients were treated with a short course of chloramphenicol, steroid or lubricant eye drops. No patients re-attended.
  
  
  CONCLUSIONS
  This report highlights the hazards of ultraviolet lamps used in public places and the need for strict guidance and enforcement of UV radiation safety protocols to avoid the potential public health risk.
