A Retrospective Study on Clinical Features and Visual Outcome of Patients Hospitalized for Ocular Trauma in Cangzhou, China

Purpose. To describe clinical features and to analyze visual outcome of ocular trauma in Cangzhou in 2012-2015, China. Methods. A retrospective study of ocular trauma cases admitted to Cangzhou Central Hospital from January 2012 till December 2015 was performed. Results. This study included a total of 507 eyes from 478 patients. Four hundred (83.7%) patients were male, with a male-to-female ratio of 5.1 : 1. Mean age was 43.6 ± 18.3 years (5-95 years). The largest age group was 45-59 years old, followed by 30-44 years old, presenting two peaks of the age distribution and accounting for 28.5% and 27.2%, respectively. The most frequent type of injuries was work-related (194, 40.6%) followed by home-related (123, 25.7%). Initial visual acuity (VA) correlated with final VA (Spearman's test, r = 0.703, p = 0.001). The Ocular Trauma Score also correlated with the final VA significantly (Spearman's test, r = 0.802, p = 0.001). Conclusions. Susceptible population of eye injuries were middle- and young-aged working groups, and the proportion of males was higher. The leading two types of ocular trauma were work-related and home-related. Initial VA was a significant predictor of the final VA and the OTS possibly had predictive value in the final VA.
