Predictive value and applicability of ocular trauma scores and pediatric ocular trauma scores in pediatric globe injuries

Abstract

AIM: To evaluate the predictive value and applicability of Ocular Trauma Score (OTS) and Pediatric Ocular Trauma Score (POTS) for closed and open globe injuries in the pediatric group. METHODS: A retrospective study of closed and open globe injuries in children age of 0-18-year-old between 2012-2019 was conducted. Medical records were collected, and injuries were classified using Birmingham Eye Trauma Terminology System (BETTS). The predictive value and applicability of both OTS and POTS to final visual acuity (VA) were analyzed. RESULTS: Of 84 patients, 59 (70.2%) presented with closed globe injuries (CGI) and 25 (29.8%) with open globe injuries (OGI). The mean of initial VA was 0.832±0.904 logMAR. OTS and POTS was calculated. Initial VA (P<0.001) and traumatic cataract (P<0.001) were significantly associated with visual outcome, followed by organic/unclean wound (P=0.001), delay of surgery (P=0.001), iris prolapse (P=0.003), and globe rupture (P=0.008). A strong correlation between OTS and POTS and final VA (r=-0.798, P<0.001; r=-0.612, P<0.001) was found. OTS was more applicable in all age group of pediatric and in contrast to POTS, it was designed for 0-15 years old. POTS requires eleven parameters and OTS six parameters. Even though initial VA was not available, we could still calculate into POTS equation. CONCLUSION: OTS and POTS are highly predictive prognostic tools for final VA in CGI and OGI’s in children.
