ABSTRACT

Aim: To identify the proportion of eyes with ocular trauma that has features considered unfavorable outcome by the Ocular Trauma Score, during the initial evaluation. Methods: Observational, analytical, retrospective prospective, cross sectional, open label study in patients with ocular trauma from a general hospital (1995 2008); patients with preexisting disease that affected visual function, previous ocular surgery and closed globe types B or C trauma were excluded. OTS Categories and 6 month prognosis were identified. The study variable was the presence of features of unfavorable prognosis: rupture, perforation, retinal detachment, endophthalmitis, and afferent pupillary defect. The proportion and 95% confidence intervals (95% C. l.) of eyes with features of unfavorable were determined, and compared with that internationally reported. Results: 540 eyes; 19 had OTS category 1 (3.5%, 95% C.l. 1.95 to 5.05), 45 category 2 (8.3%, 95% C.l.5.97 to 10.63), 102 category 3 (18.9%, 95% C.l.15.6 to 22.2), 48 category 4 (8.9%, 95% C.l.6.5 to 11 .3) and 326 category 5 (60.4%, 95% C.l.56.27 to 64.53). Eighty one eyes had features of unfavorable prognosis (15%, 95% C.l. 11 .9 to18): a rupture was found in 44 (8.1 %), endophthalmit is in 2 (0.4%), perforation in 1 (0.2%), retinal detachment in 7 (1.3%) and afferent pupillary defect in 45 (8.3%). The proportion was lower than that reported in referral centers. Conclusion: A sixth of the patients with ocular trauma had features of unfavorable prognosis, according to the Ocular Trauma Score.
