Prognostic Value of Ocular Trauma Scores in Patients With Combined Open Globe Injuries and Facial Fractures

Abstract

To assess the prognostic value of the Ocular Trauma Score in patients with combined open globe injuries and facial fractures. Retrospective cohort study. A comprehensive chart review was conducted on 25 patients (28 eyes) identified from the Elmhurst City Hospital Trauma Registry between January 1, 2000 and June 30, 2012. Elmhurst City Hospital is a level 1 trauma center located in Elmhurst, New York, USA. Average age was 52 (range 18-88) and patients were predominantly male (84%). The majority of patients had an Ocular Trauma Score of 1 (87.5%), and of these patients, 76% and 14% had final visual acuities of no light perception (NLP) and light perception/hand motion (LP/HM), respectively. These corresponded to 74% and 15% predicted by the original Ocular Trauma Score guidelines (100% sensitive and 100% specific). Ocular Trauma Score of 1 was associated with zone 3 eye wound location (P= .02). Independent of Ocular Trauma Score, initial visual acuity and frontal bone fractures were predictive of NLP (P= .006 and P= .047). Nonblindness was associated with nasal bone fractures (P= .047). This study validates the use of the Ocular Trauma Score in patients with combined facial fracture and open globe injury. The presence of facial fractures does not appear to influence visual prognosis for open globe injuries with an Ocular Trauma Score of 1. In the absence of data to calculate a full Ocular Trauma Score, initial visual acuity was the strongest predictor of final visual outcome.
