Ocular Trauma Score comparison with open globe receiving early or late care1

Abstract

Abstract Background The Ocular Trauma Score (OTS) is a scale that estimates the prognosis of injured eyes after treatment, with results that are consistent with those of longitudinal studies. The time between injury presentation and initial care has been described as a prognostic factor for visual outcome, but the OTS variables of eyes receiving early or delayed care after trauma have not been compared. Material and methods A non-experimental, comparative, retrospective, cross sectional study including patients from either gender, aged 5-80 years, with open globe trauma, without previous diseases that reduced visual acuity or previous intraocular surgery. The distribution of the OTS variables was identified. The sample was divided into two groups group 1 (time between trauma occurrence and initial care ≤ 24 hours), and 2 (time > 24 hours). The frequency of OTS categories of unfavourable prognosis (1-3) was compared between groups (χ 2 ). Results A total of 138 eyes of 138 patients were studied. The mean age of the patients was 28.8 years, with 65.2% male. The waiting time ranged 2-480 hours (mean 39.9). Group 1 had 103 eyes assigned (74.6%), and 35 to assigned to group 2 (25.4%). The proportion of categories 1-3 in group 1 (82.5%, n = 85) did not differ from that in group 2 (80%, n = 28; p = 1.0). Conclusion The proportion of OTS categories with an unfavourable prognosis did not show significant differences between the eyes who received care before or after 24 hours that could be contributed to a different outcome, besides the delay in starting treatment.
