title: Unilateral childhood blindness: a hospital-based study in Yaoundé, Cameroon.
abstract: BACKGROUND
  We performed an analytic and prospective study over a period of 12 months from January 2nd to December 31st, 2008, at the Gynaeco-Obstetric and Paediatric Hospital of Yaoundé, Cameroon. Our aim was to determine the prevalence and causes of unilateral blindness in school children aged 6 to 15 years.
  
  
  RESULTS
  Among the 1,266 children aged 6 to 15 years who were recruited, 60 presented with unilateral blindness (4.7%): 42 boys (6.96%) and 18 girls (2.71%). The mean age was 10.15 +/- 3.4 years. In patients with unilateral blindness, 65% was due to ocular trauma.
  
  
  CONCLUSIONS
  The hospital-based prevalence of unilateral blindness in children is relatively high and ocular trauma is the leading etiology.
  
  
  CONCLUSIONS
  Unilateral blindness in school children is avoidable and its incidence could be markedly reduced by emphasizing an information strategy and education based on prevention of ocular trauma. Early management of nontraumatic diseases such as infantile glaucoma and some tumors could improve outcome and avoid blindness.
