title: The ocular trauma score as a method for the prognostic assessment of visual acuity in patients with close eye injuries.
abstract: BACKGROUND
  Traumatic injuries of the eye are the most common cause of loss of visual function. In our study we performed Ocula Trauma Score (OTS). We compared with the values of visual acuity of injury and thus get an accurate model for determining the prognostic value of the final visual acuity before treatment of the patient. This model is a reliable test for both the ophthalmologist and the patient.
  
  
  OBJECTIVE
  The aim of this study was to show the socioepidemiological and demographic profile, as well as the most common mechanism in ophthalmic injuries, so to determine the final visual acuity and assessment and evaluation of sensitivity and specificity of ocular trauma score (OTS), and most importantly to determine the prognostic value final visual acuity after eye injuries.
  
  
  METHODS
  We conducted a clinical-epidemiological, retrospective-prospective study at the Department of Ophthalmology, Clinical Centre University in Sarajevo in the period 2009-2011. A sample of 124 patients with diagnosed closed of eye injuries were recruited. We applied Classifying Closed Globe Injury, performed Calculating the OTS and convert of total raw points into % chance of vision outcomes.
  
  
  RESULTS
  Comparison of age groups by gender shows that there is no statistically significant (x(2) = 5.155; p = 0.2718). Of the total number of closed eye injuries (N = 124) at the admission from groups D and E with the worst vision were 29 patients (23.38%), in group C had low visual acuity of 20 (16.12%), in group B the mean visual acuity 33 (26.61%), and in group A well-preserved visual acuity 42 (33.87%) patients. On the demission patients with well-preserved visual function was 84 (67.74%), with a medium of visual function 10 (80.64%), while the poorer visual function was 4 (3.225%) and 7 (5.645%) patients had a sense of light and projections and 1 (0.8%) patient had lost visual acuity-amaurosis. 18 (14:51%) patients did not take their eyesight due to a fresh post-operative recovery.
  
  
  CONCLUSIONS
  Data on each patient are based on the possibility of such characteristics of the mechanism of injuries presentation of vision at the beginning of disease, injury and zones relative afferent pupillary defect possibility assumptions what will be with the vision postoperatively.
