title: Factors affecting the visual outcome in hyphema management in Guinness Eye Center Onitsha.
abstract: BACKGROUND
  This study aims of determining the complications, outcome of hyphema treatment and recommend ways of enhancing good visual outcome.
  
  
  METHODS
  The records of all cases of hyphema seen from 1st January 2001 to 31st December 2005 were reviewed retrospectively. The variables analyzed were the biodata of all the patients, the agents causing hyphema, associated injuries and complications. Visual acuity at presentation, discharge and last visit was analyzed.
  
  
  RESULTS
  Seventy four patients that had hyphema were reviewed. The male:female ratio was 3.5:1. Trauma was predominantly main cause of hyphema. The common agents of injury include whip (23.2%) and fist (18.8%). The common complications were secondary glaucoma (52.5%), corneal siderosis (30.0%) and rebleeding (10%). Visual outcome is related to time ofpresentation, complications and treatment. Significant improvement was achieved following treatment.
  
  
  CONCLUSIONS
  Hyphema is a common complication of eye injuries. It is commonly associated with other eye injuries like vitreous haemorrhage and cataract. Common complications include secondary glaucoma, corneal siderosis and rebleeding. Visual outcome is dependent on time of presentation, severity and nature of complications. Visual outcome can be improved by early presentation and detection of complications and appropriate treatment.
