OBJECTIVE: To analyze the usefulness and applicability of the Ocular Trauma Score (OTS) for visual prognosis in patients with ocular trauma at the ophthalmology service of "Calixto García" clinical and surgical hospital. METHODS: A retrospective, cross-sectional and descriptive study including 171 patients diagnosed with severe ocular trauma and admitted to hospital from January 2005 to January 2008 was conducted. Each patient was evaluated by the OTS at the beginning, and the depending variable of the best corrected visual acuity (BCVA) after six-month follow-up was analyzed. This variable was analyzed to compare its initial value, ranked and stratified according the OTS and chi². The correlations between this variable and the others were determined. Accepted values of p £ 0.05 were considered as significant values. RESULTS: The average length of follow-up was 17.6 months. The mean age was 43.89 years and the male sex prevailed in 83.32 % of cases. The ocular injuries "Closed globe" were the most frequent (59.5 %), mainly contusions (47.5 %). The ocular injuries "Open globe" correlated with low initial visual acuity (r²= 0.78; p= 0.045) and low final visual acuity (r²= 0.86; p= 0.02). The values of real vs expected final visual acuity for each OTS category showed significant correlation (r²> 0.98; p< 0.002), without differences on chi² test in 25 of 29 prognostic visual probabilities. CONCLUSIONS: The Ocular Trauma Score is a system that provides an adequate and accurate prognosis of final visual acuity in patients with severe ocular trauma.
