The application of two ocular trauma score standards in paediatric open globe injuries

Abstract

Objective To assess the application of ocular trauma score (OTS) and paediatric ocular trauma score (POTS) for paediatric open globe injuries. Methods Data of 125 cases with open globe injuries aged from 3 to 14 years who were treated between March 2010 and March 2013 were retrospectively analysed. The minimum follow-up period was 1 year. The variables of the modified OTS and POTS were analysed for their predictive values in terms of the best-corrected visual acuity. The Score category of modified OTS and POTS for their predictive values in terms of the best-corrected visual acuity was analysed. Results Of 125 patients, there were 97 (77.6%) boys and 28 (22.4%) girls. Their mean age was (9.3±4.1) years old. The follow-up time was 16 to 32 months. Initial visual acuities, younger age, retinal detachments, type of injury, wound locations and vitreous haemorrhages had significant impacts on visual outcome (P<0.05). Modified OTS had high correlation with visual acuity after the treatment and was easy to perform (r=0.67, P<0.001). The Score category of the POTS correlated with the actual final visual acuities (r=0.53, P<0.001), but several POTS variables had only limited impacts on visual outcome. Conclusion The modified OTS has a high predictive value for visual outcome after open globe injuries in children. Key words: Injuries, open globe, children; Visual acuity; Score, ocular trauma
