title: Prospective validation of the Ocular Trauma Score as a prognostic model to predict vision survival in injured adult patients from a developing country.
abstract: OBJECTIVE
  To assess the prognostic value of the Ocular Trauma Score (OTS) in patients with eye injury treated in a University Hospital in South America.
  
  
  METHODS
  One hundred and ninety subjects who were victims of eye trauma with different degrees of severity were evaluated and treated accordingly. Initial OTS categories were calculated for each patient and compared to the final visual result by transforming the achieved best-corrected visual acuity (BCVA) after treatment into OTS values.
  
  
  RESULTS
  OTS visual acuity showed good correlation with the final BCVA after treatment [Spearman's ρ = 0.857, 95 % confidence interval (CI) 0.813-0.891, P < 0.0001). No difference between the predicted BCVA and achieved BCVA was noticed (P < 0.0001, Chi-square test).
  
  
  CONCLUSIONS
  The OTS provided useful information on outcomes treatment after eye trauma and can be used as a prognostic model to predict vision survival in injured adult patients from a developing country.
