BUSTAMANTE, V.; SANHUEZA, J.; WERLINGER, F.; CAMILO, P.; AGUILERA, V. & CAMPOS, M. Ocular trauma score as a predictor of visual acuity in patients with severe ocular trauma. Visual prognosis in ophthalmological urgency. J. health med. sci., 6(1):57-63, 2020.

ABSTRACT: This work aimed to determine the relationship between the visual prognosis according to the Ocular Trauma Score (OTS) and visual acuity (AV) 6 months after the ocular trauma in patients treated at the Eye Trauma Unit from the Hospital del Salvador, in Santiago, Chile. A descriptive, longitudinal and retrospective study was performed. We accessed registers of clinical patients attended for severe eye trauma from 1 January 2014 to 15 March 2015. 145 patients constitute a sample of 153 eyes. A connection was established between the OTS obtained and the AV 6 months after the trauma via the Spearman correlation coefficient. From the eyes studied, the greatest group N=68 (44.4%) qualified for OTS 3 and the smallest N=16 (10.5%) for OTS 1. Five eye categories were presented, in the beginning, most of the cases presented visual acuity with bad projection – hand motion (n=89). After six months of distribution, it moved to the category 20/40 – 20/20 (n=68). A strong relation (r=0,711 p=0,000) was found between the estimated OTS and the AV after six months of tracking. The OTS proved to have great predictive valor and is an applicable tool in our area, the data obtained showed that there is a better visual prognosis than the obtained in other studies. It is worth noting that this is the first stage where the application of OTS is assessed in Chile.

KEY WORDS: emergencies, ophthalmology, visual acuity, health care quality, eye trauma.
